Monkeypox: Asymptomatic spread of virus raises concern, study says


Recent study findings suggest some cases of monkeypox go undiagnosed due to the absence of symptoms. In such cases, testing and isolating individuals may not be sufficient to control lethal spread.

Another study conducted in France adds that the practice of “post-exposure ringing” vaccination around people with symptoms, with probable or confirmed symptoms of monkeypox infection, may again not be enough to contain the spread.

In the circular post-exposure period strategy, all people who remained in close contact with a person positive for monkeypox are vaccinated. This usually includes friends and family.

Such findings, according to experts, call for the need for high preparedness, surveillance and other strategies to measure risk and take preventive measures to contain the outbreak.

So far, 10 cases have been reported in India.

According to media reports, the global scale of the outbreak in 2022 is several countries monkeypox virus has exceeded the spread of any previous outbreak.

It is still not clear what is causing the epidemic – asymptomatic people, or other undiagnosed infections.

What is monkeypox virus?

Monkeypox is, as the name suggests, a viral zoonosis. It is a virus that is transmitted from animals to humans. Her symptoms are somewhat similar to those found in past smallpox patients. But smallpox was eradicated in 1980 and later their vaccination stopped. But the recent outbreak of monkeypox has become the most important orthopoxvirus for public health.

At first, monkey goats were widespread in countries such as central and western Africa, in countries that were close to tropical rainforests. But now we can clearly see that it is increasing in urban areas. A variety of rodents and non-human primates have animal hosts.

Symptoms of monkeypox

Anyone who contracts monkeypox is likely to develop a rash that may appear on or near the genitals (penis, testicles, labia, or vagina) or anus (butt). There is also a possibility in other areas such as hands, feet, chest, face or mouth.

The rash worsens and goes through further stages, including scabbing, before it heals.

At first, the rash may look like a pimple or blister and may be painful or itchy.

Other symptoms

* Fever
* Fever
* Swollen lymph nodes
* Fatigue
* Muscle or back pain
* Headache
* Breathing problems such as sore throat, stuffy nose or cough

One may have all or only some of the symptoms. Some people may experience flu-related symptoms before the rash appears.

While some develop a rash first, followed by other symptoms.

Many others may develop a rash.

How long do the symptoms of monkeypox last?

Symptoms of monkeypox usually begin to appear after 3 weeks of exposure to the virus. A person with flu-like symptoms will usually develop a rash 1 to 4 days later.

Symptoms of monkeypox remain active or spreading from the time symptoms appear until the rash has completely healed and all the scabs have disappeared to form a fresh layer of skin. Monkeypox illness usually lasts 2-4 weeks.
