Mpox, previously known as monkeypox, is a viral disease that can cause a distinctive rash, fever, and swollen glands, with most people recovering fully within a few weeks, though certain groups face higher risks of serious complications.

Understanding the Prognosis of Mpox

When someone receives a diagnosis of mpox, one of the first questions that comes to mind is: what does this mean for my future? The good news is that for most people, mpox is a manageable illness with a favorable outlook. Understanding what to expect can help reduce anxiety and allow patients to focus on recovery^[1].

The vast majority of individuals who contract mpox recover completely without any lasting effects. Most people experience symptoms for two to four weeks before the illness runs its course. During this time, the body’s immune system works to fight off the infection, and with proper supportive care, healing occurs naturally. The rash goes through its stages—from flat spots to blisters to scabs—and eventually all lesions heal, leaving behind fresh skin^[3].

However, the prognosis can vary depending on which type of mpox virus is involved. There are two main groups, called clades. Clade I, which is found primarily in Central Africa, tends to cause more serious illness than Clade II. Recent outbreaks of Clade I have shown less deadly patterns than in the past, but it still carries more risk. Clade II, which has been spreading globally since 2022, is generally milder. During the global outbreak of Clade IIb that began in 2022, less than 0.1% of infected people died from the disease^[2].

The outlook also depends heavily on individual health factors. People who are generally healthy and have strong immune systems typically experience the illness as a temporary inconvenience rather than a serious threat. Most will feel quite unwell during the first week or so, especially during the fever stage, but these symptoms gradually improve. Pain and discomfort from the rash can be managed with medication, and most patients can care for themselves at home with guidance from healthcare providers^[10].

Certain groups of people face a more guarded prognosis and need closer medical attention. Young children, particularly those under eight years of age, are at higher risk for severe disease. Pregnant women also face increased risks, not only for their own health but also for their unborn babies. People with weakened immune systems—such as those with advanced HIV infection, cancer patients undergoing chemotherapy, or individuals taking medications that suppress immunity—may experience more prolonged illness and more widespread viral spread. People with certain skin conditions, especially eczema or atopic dermatitis, are also at elevated risk because the virus can spread more easily across damaged skin^[17].

Statistics from African cases, where mpox has been present for many years, show mortality rates ranging from 0.1% to 10%, depending on the clade and the health status of affected populations. Most deaths have occurred in people who already had other health problems or who developed serious secondary infections. The 2003 outbreak in the United States, which affected 47 people, resulted in no deaths at all. In the global outbreak that began in 2022, fatalities have been rare, though they have occurred primarily among people with severe immune suppression^[8].

It’s important to understand that while mpox can sound frightening, especially when compared to its relative smallpox, it is significantly less severe. The name and the images of rashes can create fear, but the actual experience for most patients is one of temporary discomfort followed by complete recovery. Healthcare providers emphasize that early recognition, appropriate care, and avoiding spread to others are the keys to the best possible outcome^[14].

How Mpox Progresses Without Treatment

Understanding the natural course of mpox helps patients and families know what to expect if they choose not to pursue specific antiviral treatments—which is appropriate for most cases. Mpox is generally a self-limited disease, meaning it runs its course and resolves on its own without specific medications targeting the virus^[15].

The disease begins after an incubation period of three to 21 days following exposure to the virus. During this time, a person feels completely normal and is not contagious. Then symptoms begin, usually starting with a period called the prodromal phase. This phase marks the beginning of contagiousness. People typically experience fever, which can be quite high, along with headache, muscle aches, back pain, profound tiredness, and notably, swollen lymph nodes. The swollen glands, which may be felt in the neck, armpits, or groin, are a distinguishing feature that helps differentiate mpox from similar illnesses^[1].

About one to four days after these flu-like symptoms appear, the characteristic rash develops. In some people during recent outbreaks, the rash has appeared first, before any other symptoms, or even without other symptoms at all. The rash often begins on the face, hands, or feet and then spreads to other parts of the body. In recent cases, many people have noticed the rash starting in the genital area, mouth, or throat, particularly when transmission occurred through intimate contact^[4].

The rash itself goes through a predictable series of changes over approximately two to four weeks. It starts as flat, red spots on the skin called macules. Within a day or two, these spots become raised bumps called papules. The papules then develop into fluid-filled blisters called vesicles, which look similar to chickenpox but are typically firmer and more deeply set in the skin. These vesicles then fill with thick, yellowish fluid, becoming pustules. Eventually, the pustules crust over, forming scabs. Finally, the scabs fall off, revealing healed skin underneath. A person remains infectious until all scabs have completely fallen off and fresh skin has formed^[11].

The number of lesions varies dramatically from person to person. Some individuals develop hundreds or even thousands of spots, while others may have only a few—or even just one solitary lesion. The rash can be intensely uncomfortable, causing pain, itching, or both. When lesions develop in certain locations, they can cause specific problems. Mouth sores can make eating and drinking difficult. Lesions in the genital area or around the anus can cause significant pain, especially during urination or bowel movements. Some people develop proctitis, which is inflammation inside the rectum that causes severe pain and sometimes bleeding^[17].

Throughout the illness, without specific treatment, the body’s immune system gradually gains control over the virus. Fever typically breaks within the first week. Energy levels slowly improve, though fatigue may persist for some time. The rash continues its progression through the stages regardless of treatment, though supportive care can make the process more comfortable. Pain management, hydration, good nutrition, and careful skin care are the mainstays of helping the body heal naturally^[1].

For most healthy individuals, this natural progression leads to complete recovery without any permanent effects. The immune system develops antibodies against the virus, which may provide some protection against future infections, though the duration of this immunity is still being studied. Once all scabs have fallen off, people can return to their normal activities without risk of spreading the virus to others^[21].

Possible Complications That May Arise

While most people with mpox recover without problems, it’s crucial to be aware of possible complications that can develop. These complications can affect various parts of the body and may require additional medical intervention beyond basic supportive care^[10].

One of the most common complications is secondary bacterial infection of the skin lesions. When the rash lesions break open or when people scratch them, bacteria can enter the wounds. These bacterial infections can cause increased redness, warmth, swelling, and pus formation beyond what the mpox virus itself causes. In severe cases, bacterial infections can enter the bloodstream, causing sepsis, a life-threatening condition where the body’s response to infection damages its own tissues. Sepsis requires emergency treatment with intravenous antibiotics^[17].

Eye involvement is a particularly concerning complication. When mpox lesions develop on or around the eyes, or when the virus is inadvertently transferred to the eyes by touching them with contaminated hands, it can cause serious problems. Eye infections from mpox can lead to pain, redness, discharge, and sensitivity to light. If not treated promptly, infection of the eye can result in scarring of the cornea and permanent vision loss. This is why healthcare providers strongly advise people with mpox to avoid wearing contact lenses and to be extremely careful not to touch their eyes^[10].

Respiratory complications can occur when the virus affects the lungs. Pneumonia, or lung infection, can develop either from the mpox virus itself or from secondary bacterial infections. People with pneumonia may experience difficulty breathing, chest pain, and persistent cough. This complication is more common in people with weakened immune systems but can occasionally affect otherwise healthy individuals. Some cases require hospitalization and oxygen support^[17].

Neurological complications, though rare, can be severe. Encephalitis, or inflammation of the brain, can cause confusion, seizures, severe headache, and changes in consciousness. This serious complication requires immediate medical attention and hospitalization. Some people may also experience myocarditis, which is inflammation of the heart muscle, causing chest pain, irregular heartbeat, and shortness of breath^[10].

For people with extensive rash involvement, especially in the mouth, throat, genital areas, or rectum, complications can arise from difficulty eating, drinking, urinating, or having bowel movements. Severe pain in these areas can lead to dehydration if people avoid drinking fluids. Difficulty eating can result in inadequate nutrition at a time when the body needs extra energy to fight the infection. Some people require hospitalization for intravenous fluids and pain management^[16].

Pregnant women face additional risks. The virus can pass from mother to fetus through the placenta, potentially causing serious outcomes including miscarriage, stillbirth, or preterm delivery. Limited data suggest that pregnancy complications related to mpox can be serious. During labor and immediately after birth, there is also risk of transmission from mother to newborn through direct contact. These risks are why pregnant women with mpox require close monitoring and specialized care^[6].

People with severe immune suppression face the highest risk of complications. In these individuals, the virus may spread uncontrollably throughout the body, causing widespread lesions on internal organs as well as skin. This uncontrolled viral spread can be life-threatening and may require treatment with antiviral medications, even though these treatments are still being studied for effectiveness in mpox^[10].

Long-term complications are less well understood because mpox has only recently become widespread outside of Africa. Some people report persistent pain in areas where they had lesions, even after healing. Scarring can occur, particularly if lesions become infected or are in areas subject to friction. The psychological impact of having a stigmatized illness and dealing with visible rashes can also have lasting effects on mental health and well-being^[21].

Impact on Daily Life and Activities

Living with mpox affects much more than just physical health. The illness can significantly disrupt daily routines, work, relationships, and emotional well-being. Understanding these impacts helps patients and families prepare for the challenges ahead during the isolation period^[20].

The most immediate impact is the need for isolation. People with mpox must stay away from others to prevent spreading the virus. This means missing work or school for several weeks—potentially the entire period from when symptoms start until all scabs have fallen off and fresh skin has formed. For many people, this extended absence creates financial stress, especially if they don’t have paid sick leave. Students may fall behind in their studies, requiring arrangements with teachers for make-up work^[16].

Physical activities become limited not just because of the need to isolate, but because the illness itself causes significant fatigue and discomfort. During the acute phase, many people feel too tired to do much beyond rest. The fever and body aches can make even simple tasks feel exhausting. Later, even as energy returns, the rash can make movement painful, especially if lesions are in areas that experience friction, such as the feet, hands, or genital region. Exercise, sports, and other physical hobbies must be suspended until recovery is complete^[23].

Social isolation takes an emotional toll. Humans are social creatures, and being cut off from friends, family, and normal social interactions for weeks can lead to feelings of loneliness, sadness, and anxiety. Video calls and messaging can help maintain connections, but they don’t fully replace in-person contact. The visible nature of the rash, especially if it affects the face, can make people self-conscious even during virtual interactions. Some people report feeling like they’re being judged or avoided, even by those trying to be supportive^[19].

Intimate relationships face particular challenges. Sexual activity must completely stop during illness and for some time after, as this is a major route of transmission. This can strain romantic relationships, requiring open communication and patience from both partners. The rash often affects genital areas, which can be embarrassing to discuss even with a partner. Fear of having spread the virus to a partner before symptoms appeared can cause guilt and anxiety^[22].

Living situations can become complicated. People who live with others—whether family members, roommates, or in shared housing—must try to isolate within their home. Ideally, this means staying in a separate room and using a separate bathroom. When separate bathrooms aren’t available, extensive cleaning after each use is necessary. Shared spaces like kitchens become challenging to navigate. Some people find they need to move temporarily to another location if isolation at home isn’t feasible, which creates additional stress and expense^[20].

Caring for oneself during illness presents practical challenges. The lesions require careful management—covering them with bandages, avoiding scratching, keeping them clean. This routine takes time and attention. Pain can make simple self-care tasks difficult. Washing hands frequently, which is essential for preventing spread, can be painful if there are lesions on the hands. Eating and drinking may be difficult if there are mouth sores. Even getting dressed can be uncomfortable when clothing rubs against lesions^[16].

Pet owners face an additional concern. The virus can spread to animals, so people with mpox should avoid contact with pets. This means arranging for someone else to care for pets during illness, or at minimum, taking precautions like wearing gloves and masks when necessary contact is unavoidable. For people who live alone with pets they love dearly, this separation adds another layer of stress^[20].

The stigma associated with mpox can be one of the most challenging aspects. Despite being a disease anyone can contract through various types of close contact, mpox has sometimes been incorrectly portrayed as only affecting certain communities. This has led to discrimination, blame, and social stigma. People may feel ashamed to disclose their diagnosis or worry about judgment from others. This stigma can prevent people from seeking care promptly or being honest with contacts who need to be notified^[19].

Financial impacts extend beyond missed work. Medical appointments, testing, medications for symptom management, and supplies for wound care all have costs. Even with insurance, copays and deductibles can add up. People may need to arrange for food and supply delivery, which often costs more than shopping in person. Transportation to medical appointments, especially if public transit isn’t safe to use, can be expensive^[23].

Recovery brings relief but doesn’t mean all effects immediately disappear. Some people experience lingering fatigue for weeks after acute symptoms resolve. Skin where lesions were may be sensitive or discolored for months. Returning to normal activities requires gradual adjustment. Some people find they’re anxious about intimacy or social contact even after they’re no longer infectious. Rebuilding confidence and routines takes time and patience^[21].

Supporting Family Members Through the Illness

When someone in a family is diagnosed with mpox, everyone is affected. Family members play a crucial role in supporting the ill person while also protecting themselves and managing their own emotions during this challenging time^[20].

The first step for families is understanding how the virus spreads and what precautions are necessary. Mpox spreads primarily through direct skin-to-skin contact with the rash or body fluids, and through contaminated materials like bedding and clothing. Less commonly, it can spread through respiratory droplets during prolonged face-to-face contact. Armed with this knowledge, families can take appropriate precautions without excessive fear. The person with mpox should ideally stay in a separate room, use a separate bathroom if possible, and minimize contact with others until all scabs have healed^[20].

Practical caregiving involves multiple tasks. Family members may need to help with grocery shopping, preparing meals, and delivering them to the isolated person. They might assist with cleaning tasks, always wearing gloves and avoiding direct contact with contaminated items. Laundry needs special attention—items used by the ill person should be placed in plastic bags before transport to the washing machine and washed separately with hot water. Household members should avoid touching these items directly^[20].

Monitoring the ill person’s condition is an important family role. Family members can watch for signs of complications that require medical attention, such as difficulty breathing, severe pain, confusion, or signs of dehydration. They can help the ill person keep track of symptoms, medications, and appointments. Having someone to report concerns to healthcare providers can be valuable, especially when the ill person is too tired or uncomfortable to communicate effectively^[23].

Emotional support may be the most important contribution family members make. Being isolated and sick is lonely and frightening. Regular check-ins, even if just through a closed door or video calls, help the ill person feel less alone. Reassurance that the family is there and that recovery will come can be comforting. Listening to fears and concerns without judgment creates a safe space for honest communication^[19].

Children in the household need special consideration. If a parent has mpox, explaining the situation in age-appropriate terms helps reduce fear. Children need reassurance that the sick person will get better and that the separation is temporary. Depending on ages, children may be frightened by a parent’s appearance, angry about disrupted routines, or worried they caused the illness somehow. Maintaining as much routine as possible and giving children ways to show care—like drawing pictures or making cards—helps them cope^[12].

Family members who have had close contact with the ill person before diagnosis should monitor themselves for symptoms for three weeks. They should know what symptoms to watch for and have a plan for what to do if symptoms develop. Some may be eligible for vaccination after exposure, which can prevent or reduce illness. The local health department can provide guidance on whether post-exposure vaccination is recommended^[1].

Managing household pets requires attention. Pets should be kept away from the ill person if at all possible. If the ill person was the primary caregiver for pets, other family members need to take over all pet care duties. If pets had close contact with the ill person during the time they were contagious, the health department should be notified so pets can be monitored for signs of infection^[20].

Families should be prepared for the isolation period to last several weeks. This requires planning for the long term rather than assuming it will be over quickly. Stocking up on supplies, arranging flexible work schedules, and setting up systems for meal preparation and delivery help make the extended period more manageable. Regular family meetings, even if virtual, help everyone stay informed and feel included in decisions^[20].

Communication with extended family and friends requires balancing privacy with honesty. The ill person may or may not want others to know about their diagnosis. Stigma makes this decision complex. Families should respect the ill person’s wishes while also recognizing that close contacts may need to be informed. Finding ways to ask for help—whether practical assistance or emotional support—without necessarily disclosing the specific diagnosis can be a middle ground^[19].

Healthcare providers should be partners in the family’s caregiving efforts. Families shouldn’t hesitate to call with questions or concerns. Understanding what symptoms are expected versus which require immediate attention helps families feel more confident in their caregiving. Healthcare providers can also connect families with resources like food assistance, financial support, or mental health services if needed^[16].

After recovery, families may need time to readjust. Routines need to be reestablished, relationships reconnected, and living spaces fully cleaned and disinfected. Some family members may be anxious about the illness recurring or being transmitted, even after the ill person is fully recovered. Open conversation about these feelings and patience as everyone adjusts back to normal helps the entire family heal together^[23].

What Families Should Know About Clinical Trials for Mpox

Clinical trials are research studies that test new treatments or gather information about diseases. For mpox, several clinical trials have been conducted or are ongoing to better understand treatments and gather data about the illness. Families might wonder whether participating in clinical trials could benefit their loved one^[10].

Currently, there are no treatments specifically approved for mpox. The disease is generally self-limited, and most people recover with supportive care alone—rest, fluids, pain management, and careful wound care. However, researchers have been studying whether certain antiviral medications might help, particularly for people with severe disease or at high risk for complications^[10].

One medication that has been studied in clinical trials is tecovirimat, also known by the brand name TPOXX. This antiviral drug was originally developed and approved for treating smallpox, a related virus. During the global mpox outbreak that began in 2022, tecovirimat was made available to certain patients through a special program called expanded access or compassionate use. This allowed doctors to prescribe the medication while also collecting information about its effects^[10].

Two major clinical trials, called PALM007 and STOMP, were launched to formally test whether tecovirimat helps people with mpox recover faster. These studies included some participants who received tecovirimat and others who received placebo (inactive treatment), and researchers compared how quickly the rash healed in each group. Results released in 2024 showed that while tecovirimat was safe and didn’t cause serious side effects, it did not significantly reduce the time it took for mpox lesions to heal compared to placebo. This was disappointing news, as many had hoped this medication would prove helpful^[10].

Despite these results, tecovirimat remains available for certain high-risk patients through the expanded access program. Healthcare providers may still consider offering it to people who have severe disease, are severely immunocompromised, or have complications affecting the eyes or other vital areas. The decision to use tecovirimat involves weighing potential benefits against the fact that clear evidence of effectiveness is lacking^[10].

Other medications have also been studied or considered for mpox treatment. Cidofovir and brincidofovir are antivirals that have shown activity against pox viruses in laboratory studies and animal models. However, data on their effectiveness in human mpox cases is limited. Cidofovir has significant side effects, particularly kidney toxicity, which limits its use. Brincidofovir was designed to have fewer side effects than cidofovir, and it has been approved for smallpox treatment, but studies in mpox patients are still needed^[15].

Another product being studied is vaccinia immune globulin (VIG), which contains antibodies that might help fight orthopoxviruses like mpox. However, there is limited data on whether VIG actually helps patients with mpox recover, and it is only available through special programs^[15].

Families should understand that clinical trials serve two purposes: they may potentially help the participant, but they also gather valuable information that will benefit future patients. Participating in a trial means agreeing to follow specific protocols, which might include extra testing, more frequent medical visits, and detailed tracking of symptoms. Participants might receive an active treatment or a placebo, though in many studies, all participants receive standard supportive care regardless of which study group they’re in^[10].

If a family member is interested in clinical trials, they should discuss this with their healthcare provider. Not everyone will be eligible for trials—there are usually specific criteria about age, severity of illness, other health conditions, and timing of enrollment. Healthcare providers can explain what trials might be available and whether the potential benefits and risks make sense for that individual’s situation^[10].

Families should also know that declining to participate in a clinical trial will not affect the quality of care their loved one receives. Standard supportive care is effective for most people with mpox, and the decision about clinical trials should be based on individual circumstances, preferences, and values. Some people value contributing to scientific knowledge even if they personally may not benefit, while others prefer to focus simply on getting through the illness with standard care^[10].
