In recent years, there has been a rise in cases of monkeypox, a virus that has gained international attention due to its reemergence outside of endemic regions in Africa. This article explores what monkeypox is, how it is transmitted, what tests are used to diagnose it, and how it differs from other viral diseases like COVID-19.
Monkeypox is a zoonotic viral disease, meaning it is transmitted from animals to humans. It is caused by the monkeypox virus, an orthopoxvirus that belongs to the same genus as the smallpox virus. Although monkeypox symptoms are generally less severe than those of smallpox, it is still a concerning public health issue, especially due to its potential to spread between humans.
The symptoms of monkeypox typically include fever, severe headache, muscle pain, fatigue, and a characteristic rash that begins on the face and spreads to other parts of the body. The rash evolves from spots to fluid-filled pustules and eventually forms scabs.
The virus is primarily transmitted through direct contact with body fluids, skin lesions, or mucous membranes of an infected person. It can also spread via contaminated objects and respiratory droplets in cases of prolonged close contact.
To confirm a case of monkeypox, polymerase chain reaction (PCR) tests are primarily used. These tests focus on detecting the genetic material of the virus in samples taken from skin lesions, such as pustules or scabs, and are highly accurate. Other tests may include viral cultures and serological studies, although these are less commonly used than PCR.

COVID-19 diagnosis is also primarily conducted through PCR tests, which detect the genetic material of the SARS-CoV-2 virus in samples taken from the nose or throat. Rapid antigen tests, which look for viral proteins, are another option and provide results within minutes, though with less accuracy. Additionally, antibody tests can indicate past infection but are not used to diagnose active infections.
Monkeypox and COVID-19 are viral diseases with distinct transmission modes and symptoms, though both require specific diagnostic tests for confirmation. It is crucial to be informed about the differences and appropriate diagnostic methods to make informed health decisions.
The PCR test performed on skin lesion samples is the most accurate for diagnosing monkeypox.
If you exhibit symptoms consistent with monkeypox, such as a characteristic rash and fever, you should seek medical attention immediately for testing and treatment.
Yes, although rare, it is possible to be infected with both viruses simultaneously, underscoring the importance of testing and medical consultation.
Stay informed and take precautions to protect yourself from both monkeypox and COVID-19. Diagnostic tests play a crucial role in identifying and managing these viral diseases.
