Prior to discovery of evidence of person-to-person transmission of the Chapare virus in Bolivia, MS received a warning from the mysterious virus that has symptoms similar to dengue and Ebola. This virus causes a hemorrhagic fever and, last year, five cases were confirmed near La Paz and three of them were fatal.
Those infected with the Chapare virus had symptoms such as fever, headache, body pain, nausea and bleeding gums, according to virologist María Morales-Betoulle, of the United States Center for Disease Control and Prevention. He said that in South America in general, when people see cases with these symptoms, they immediately think of dengue and do not necessarily think of a rare virus like Chapare.
According to national media, when the team in Bolivia realized that the disease was not caused by dengue, they sent patient samples to a CDC laboratory in the US with advanced genome sequencing capabilities. It was there that, to the surprise of the researchers, the virus was identified as Chapare. The virus in question is much more difficult to transmit than the coronavirus. Although the coronavirus is easily transmitted through the respiratory tract, Chapare is transmitted through direct contact with bodily fluids at the peak of the disease.
People who are at risk of contracting the Chapare virus are those who have close contact with patients, such as health professionals and family members who care for people at home. Furthermore, the Chapare virus is very geographically specific. The report provided some evidence that the small-eared pygmy rice mouse may carry the virus, and these mice are only found in certain parts of South America.
Monitoring Center in MS
The SES (State Department of Health) reported that it has a center where monitoring is carried out, in case of manifestation of the disease. The center informed the city of Corumbá to be on the lookout for possible suspected cases. The secretariat points out that this year there were no cases of the disease, so there are no risks of transmission in the municipalities that border the neighboring country.
The secretariat explains that it received a statement from the Ministry of Health informing about the study in which scientists discovered the Chapare virus, which can be transmitted between humans, after records in Bolivia last year. The SES reinforces that only five cases were registered last year and there was no registration of the disease in Brazil.
The announcement of the study was made to the CIEVS (Center for Strategic Information and Response in Health Surveillance), which detects, evaluates and monitors information on the practice of health surveillance. That is, the center monitors, creating means of identification and early intervention in public health emergencies of state and national relevance, estimating the risk of expansion of these events.
“This Center is available 24 hours a day, every day of the year, becoming the gateway for immediate mandatory notifications from the State Department of Health and, consequently, the bridge between the State and the Ministry of Health” , SES reported. .
The secretariat explains that the Statement from the Ministry of Health on the virus it was standard procedure. The CIEVS sent this statement to the Corumbá Municipality Surveillance so that the Health Network is aware of possible suspected cases that meet the definition, as well as there is already a list of diseases under monitoring. SES highlights that there are no recently registered cases of the disease.
