Mpox Outbreak in Africa Triggers Global Health Emergency: What You Need to Know
As the world grapples with various health challenges, another significant threat has emerged—an outbreak of mpox, a viral disease that has prompted the World Health Organization (WHO) to declare a global health emergency. This alarming situation stems from a severe and highly contagious strain of mpox spreading across central Africa, particularly in the Democratic Republic of Congo and surrounding nations. The virus has now been detected in at least 13 African countries, leading to over 17,000 infections and more than 500 deaths just this year.
What is Mpox?
Mpox, formerly known as monkeypox, is a viral infection belonging to the same family of viruses that cause smallpox. Despite the similarity in names, mpox is not related to chickenpox. The virus was first discovered in 1958 in monkeys, hence its original name, but it has since been renamed to mpox to avoid stigma. Mpox is zoonotic, meaning it can be transmitted from animals to humans, but it also spreads from person to person, particularly through physical contact.
There are two primary strains of the mpox virus—Clade I and Clade II. Clade I is endemic to central Africa, while Clade II is found in West Africa. The current outbreak is linked to a more virulent and easily transmissible variant of Clade I, known as Ib. This strain is proving more deadly and has already resulted in a concerning number of fatalities.
Symptoms and Transmission
The symptoms of mpox can resemble those of the flu, including fever, headache, body aches, and exhaustion, but one of its most distinguishing features is a rash that typically appears within one to three days after fever onset. This rash starts on the face and spreads to other parts of the body, including the hands, feet, chest, and even the genitals. Over time, the rash turns into pus-filled blisters that eventually dry out and fall off. The incubation period for mpox— the time between infection and the appearance of symptoms—ranges from 5 to 21 days.

Mpox is primarily transmitted through direct contact with bodily fluids, respiratory droplets, or contaminated objects, such as bedding. While it can also spread through respiratory droplets, this usually requires prolonged close contact, making the virus less contagious than diseases like COVID-19.
Global Response and the Risk to the U.S.
The WHO's declaration of mpox as a public health emergency of international concern is a call to action for global and regional health authorities. This status enables a more coordinated international response, prioritizing vaccine distribution and other critical resources to curb the spread of the virus.
Although the new strain has not yet reached the United States, health officials are on high alert. The U.S. Centers for Disease Control and Prevention (CDC) has already issued health alerts and travel notices, urging healthcare providers to monitor for symptoms and inquire about recent travel to affected regions. While the risk in the U.S. remains low at the moment, the situation is being closely monitored.
Treatment and Vaccination
Vaccines are available and highly recommended for individuals in high-risk groups. The JYNNEOS vaccine, administered in a two-dose series, has proven effective against both Clade I and Clade II strains of mpox. Despite this, a significant challenge remains in ensuring that people return for their second dose, which is crucial for full protection.
The situation is particularly dire in Africa, where an estimated 10 million vaccine doses are needed to control the outbreak. The U.S. has pledged to donate 50,000 doses to Congo, but experts agree that a much larger international effort is required to stem the spread of this dangerous virus.
As the world faces yet another health crisis, it is imperative to remain vigilant and informed. The mpox outbreak in Africa is a stark reminder of the interconnectedness of global health. While there is no need for panic, the situation demands careful monitoring and swift action to prevent a wider spread. Public health officials around the globe are working tirelessly to contain the outbreak, and it is crucial that we all stay informed and prepared for any developments.
