Experts: Monkeypox deaths outside Africa still low

4 confirmed cases outside the African continent in recent daysmonkeypoxcases of death, for the first timeBrazil, 2 cases in Spain, India also confirmed 1 death today. Still, Brazilian experts say the death rate from monkeypox is very low.

Symptoms of monkeypox persist for 2 to 4 weeks and more than 99% of infected patients recover. But some, such as children under the age of 8, people with compromised immune systems, people with a history of inflammatory skin conditions, and pregnant and breast-feeding women are at higher risk for more serious complications.

According to the World Health Organization (WHO), from January to July 22 this year, there were 5 monkeypox deaths worldwide, all in the African continent, including 3 in Nigeria and 2 in the Central African Republic.

The Brazilian Ministry of Health confirmed the first death from monkeypox in Brazil on 29 July. The deceased was a 41-year-old man with a weakened immune system and lymphoma, which quickly deteriorated to death.

Deaths from monkeypox are still rare. Mirian Dal Ben, an infection control specialist at the Syrian Lebanese Hospital in So Paulo, toldEpidemicMortality rate, which is less than 1%.

According to Our World In Data, there are more than 21,000 confirmed cases of monkeypox worldwide, with 8 deaths so far, the mortality rate is only 0.0003%, or 1 in 2,600 people who test positive, 1 person dies. Went.

These figures are well below the previous WHO estimate that in the past few outbreaks in African countries, the mortality rate for monkeypox has been between 3% and 6%.

The low mortality rate observed till date is related to 2 main factors. First, there has been a lack of accurate and detailed information about monkeypox, which has been endemic for decades in many African countries.

Alexandre Naim Barbosa, vice president of the Brazilian Society for Infectious Diseases, pointed out that perhaps cases of monkeypox in Africa are already mild, but because they are poor countries and monkeypox is a neglected disease, it may only be seen in severe cases. Officers’ attention. But now that monkeypox is spreading in rich countries with better notification and surveillance systems, even mild cases can provide detailed information about the disease and its symptoms.

The second factor is related to the type of virus that spreads more strongly outside Africa. As far as is known, there are at least 2 strains of monkeypox, namely the Central African (Congo Basin) and West African strains.

Dorbin said the death rate is high in the Congo Basin, reaching 6 percent of cases, but that most infections outside Africa are from the West African strain, with a mortality rate of less than 1 percent. So far, these deaths have been rare, and the deceased are usually infected with non-viral strains.

Barbosa explains that any lesion that begins as edema or small red spots and develops into plaques with fluid, forming sores and scabs, is potentially monkeypox. If the test confirms monkeypox, it is recommended to avoid close contact with others and isolate until the wound has completely healed, to slow the spread of the virus and prevent new transmission chains in the community.

Currently, only a few countries in Europe and North America have introduced monkeypox vaccination. The Brazilian Ministry of Health continues to negotiate with the Pan American Health Organization (PAHO), but there is no definite news about receiving a monkeypox vaccine. Not there.
