What is mpox, and why should you care? Mpox is an infectious viral disease that can strike fear into the hearts of many. It’s like a sneaky thief, lurking in the shadows of our world, waiting to make its presence known through a rash with blisters, fever, swollen lymph nodes, and more. But what exactly does this mean for you and me? Let’s dive deeper.
Understanding mpox: A Viral Intruder
Mpox is caused by the monkeypox virus, which can spread like wildfire through direct contact with infected skin or body fluids. It’s not just a one-time encounter; it can even spread through sexual contact. Imagine if every touch could potentially be a handshake with danger – that’s how risky this disease can be.
Endemic Areas and Global Outbreaks
Mpox is endemic in Central and Western Africa, where the virus has been quietly spreading for decades. But it’s not just a local issue; since 1970, we’ve seen global outbreaks that have caused concern worldwide. The most recent one, declared a public health emergency of international concern by the WHO, was a stark reminder of how quickly this disease can spread.
How Does It Spread?
The virus spreads through various means: bites, scratches, hunting, skinning, cooking, broken skin, or mucosal surfaces. Small mammals act as reservoirs for the virus in these regions, making it even harder to contain. Think of them as tiny carriers, spreading the disease without knowing.
Signs and Symptoms
People with mpox usually become symptomatic about a week after infection, but not everyone will exhibit the complete range of symptoms. The rash comprises numerous small lesions that appear on various parts of the body, typically lasting around ten days. Some people may manifest only a single sore or hundreds of sores. An individual can be infected without showing symptoms.
Complications and Risk Groups
Complications include secondary infections, pneumonia, sepsis, encephalitis, and loss of vision following corneal infection. Persons with weakened immune systems are more likely to develop severe cases. If infection occurs during pregnancy, it may lead to stillbirth or other complications.
Diagnosis and Prevention
Diagnosis involves clinical differential diagnosis and polymerase chain reaction (PCR) testing of skin lesions. A new diagnostic test approved by the WHO enables detection in under two hours. Prevention measures include vaccination with various vaccines developed for smallpox, including MVA-BN, LC16, OrthopoxVac, and ACAM2000.
Vaccination and Treatment
Vaccination is recommended for high-risk individuals, those investigating outbreaks, caregivers, and close contacts of infected individuals or animals. The CDC has made detailed recommendations for infection control, including standard precautions and additional measures. Healthcare providers wear protective gear when treating patients with mpox.
Treatment for mild mpox cases involves supportive care, such as pain or fever control, and isolation at home. Those at high risk from the disease include children, pregnant women, elderly, and immunocompromized individuals. Hospital admission is recommended for these groups.
Global Impact
The World Health Organization has called on manufacturers to submit their diagnostic tests for emergency review due to a recent outbreak in the DRC. The WHO has declared mpox a global public health emergency. Evidence suggests the virus is evolving to be more transmissible among humans and can infect various host species, leading to concerns about new natural reservoirs or future pandemics.
Outbreaks and Cases
Without a major vaccination campaign, mpox outbreaks in humans will continue indefinitely in endemic areas with ongoing risk of global epidemics. Frequent outbreaks have occurred in endemic countries in tropical Africa, often with poor healthcare infrastructure. In the US, several cases of mpox were reported, including a 2003 outbreak and an August 2022 clade I outbreak in refugee camps.
Conclusion
Mpox remains present outside Africa at low levels, with increasing cases reported in 2023, including sexual transmission in the Democratic Republic of Congo. The WHO added monkeypox virus to its list of “priority pathogens” that could cause a pandemic in 2024. Frequent outbreaks have occurred in endemic countries, often with poor healthcare infrastructure.
As we navigate through this complex landscape, it’s crucial to stay informed and take necessary precautions. After all, knowledge is the first step towards prevention.
