Emerging hemorrhagic fever in Bolivia of human transmission


A presentation at the annual meeting of the American Society of Tropical Medicine and Hygiene (ASTMH) has announced that a deadly virus in Bolivia can pass from human to human. Chaper virus, which causes hemorrhagic fever, was previously seen only in small groups of patients, But a recent outbreak saw many emergency service workers infected after coming in contact with a patient with the disease. In 2019, at least three people were infected near La Paz, the capital of Bolivia, of which two died of the disease.

“A young medical resident, an ambulance drug and a gastroenterologist contracted the virus after encounters with infected patients, and two of these health workers later died,” Katlin Kossaboom, an epidiologist with the Centers for Disease Control and Prevention he said. (CDC), in conference. “We now believe that many bodily fluids can possibly carry the virus.”

All health workers have searched to deal with suspected cases of the Chaser virus to avoid exposure to potential contaminants including blood, urine, saliva, and semen. The exact mechanism through which the disease passes from one person to another is not yet known, but it is suspected that saliva may play a role.

An ambulance drug that remains is captured from an infected medical resident to the chaper whom he resurrected on his way to the hospital. The same medical resident, who died of the disease, is believed to have contracted it after extracting saliva from an infected patient. There was also evidence of viral RNA in a semen sample 168 days after infection with the virus, indicating that sexual transmission is another way in which the virus can spread.

The chaper is an arenavirus, a group of pathogens that includes the Lassa virus and Machupo virus, both causing fatal outbreaks in West Africa and Bolivia, respectively. These arenaviruses cause hemorrhagic fever, which results in patients suffering from multiple organ complications and bleeding. This condition is also found in Ebola patients and is a complex for the management of health care teams.

The source of the 2019 outbreak of the chaper in Bolivia remains to be confirmed, but viral RNA was found in rodents closer to the previously identified patient’s home. Having sufficient sources of viral RNA by itself is not enough evidence to eradicate rodents, but provides important insights that could help future investigations to reduce the cause. The rodents included were Peggy Rice rats and small-ear Pygmy Rice mice, both found in Bolivia and some of its neighboring countries.

“While much is still unknown about the chaper virus, it is commendable how quickly this team develops a clinical trial, verifies human-to-human transmission, and uncovers early evidence of the virus in rodents Was able to do, ”said ASTMH Joel Breiman. During the conference. “It is a valuable lesson that international scientific teams are equipped with the latest equipment and freely sharing their insights, which are our best front-line defense against the disruptive threats of deadly infectious diseases.”
