Mpox: What You Need to Know About This Emerging Disease

Mpox, also known as monkeypox, is a rare but potentially serious viral disease that is causing increasing concern worldwide. Although it was first identified in monkeys in the 1950s, the disease has gained significant attention in recent years, with several outbreaks reported in various countries.

What is Mpox?

Mpox is caused by the monkeypox virus, an orthopoxvirus closely related to the smallpox virus. While smallpox was eradicated thanks to a global vaccination campaign, Mpox continues to circulate, primarily in Central and Western Africa, where it is endemic. However, cases have been reported outside these regions, raising concerns about its global spread.

Symptoms and Disease Progression

Mpox presents with symptoms similar to those of smallpox, although they are generally less severe. Early signs include fever, headache, muscle aches, and a general feeling of fatigue. Subsequently, a characteristic rash appears, often on the face, before spreading to other parts of the body. The skin lesions go through several phases, progressing from macules to vesicles, pustules, and finally scabs.

The majority of Mpox cases resolve spontaneously within two to four weeks, but complications can occur, particularly in immunocompromised individuals or young children.

Diagnosing Mpox

The diagnosis of Mpox is primarily based on a clinical examination of symptoms and travel history or exposure to high-risk areas. However, due to the similarity of symptoms with other infections, such as chickenpox, a definitive diagnosis requires laboratory tests.

Samples are generally taken from skin lesions, specifically fluid from vesicles or scabs. These samples are then submitted for polymerase chain reaction (PCR) analysis, which detects the DNA of the Mpox virus. This method is considered the most reliable for confirming the presence of the virus.

In some cases, serological tests may also be performed to detect the presence of specific antibodies, which can indicate a past or current infection.

Transmission and Prevention

Mpox is transmitted primarily through direct contact with body fluids or skin lesions of an infected person, or via respiratory droplets during close contact. The virus can also be transmitted through contaminated surfaces or by consuming meat from infected animals.

To prevent the spread of Mpox, it is essential to follow rigorous hygiene measures, such as washing hands frequently, avoiding direct contact with sick individuals, and wearing a mask if an infection is suspected. Additionally, certain vaccines, originally developed for smallpox, can offer some protection against Mpox.

The Current Situation in Quebec

In Quebec, the situation is under control, but health authorities are closely monitoring the evolution of the disease. Healthcare professionals, like myself, are trained to recognize the signs of Mpox and to manage suspected cases appropriately. Individuals presenting symptoms compatible with Mpox should promptly consult a doctor to receive an accurate diagnosis and appropriate care.

Conclusion

Although Mpox remains a relatively rare disease, its re-emergence on the global stage reminds us of the importance of public health vigilance. Prevention, early screening, and rapid case management are essential to limit the spread of this disease.
