Alert for the dispersion of a rare virus in Latin America

The reappearance of Mayaro virus, transmitted by mosquitoes, ignites the alarms of doctors and calls to take precautions.

¿Qwhat is the Mayaro virus?

It was discovered in the 1950s. It is located in the tropical regions of South America and Central America and It is transmitted by mosquito bite.

The cycle of people infected with this virus is similar to yellow fever. It is characterized by elevated body temperature and symptoms very similar to dengue. In addition, it causes joint pains that can last for months.

The reappearance of this virus has ignited alerts from Health specialists in Argentina. "Now it is known that Aedes aegypti also transmits it, an insect of wide distribution in Argentina and other countries, which raises the risk that this pathogen continues to expand its endemic zone and even affect regions where it has not yet circulated ", Dr. Antonio Montero, scientific director of the Center for Tropical Medicine and Emerging Infectious Diseases of the Faculty of Medical Sciences of the National University of Rosario (UNR),

"It is a pathogen that we take into account and that is included in the differential diagnosis of undifferentiated or nonspecific febrile syndrome, " he claimed Dr. Tomás Orduna, Tropical Infectologist physician and Head of the Service of Regional Pathologies and Tropical Medicine of the Infectious Hospital Francisco J. Muñiz, of Buenos Aires. He also pointed out that this virus is under surveillance in Argentina.

Measures to take

Orduna affirmed the need to increase in the region the surveillance measures for both Mayaro virus and other arboviruses, which are those transmitted by arthropods, mostly insects.

Orduna also stated that in the Amazon zone and in other tropical and subtropical regions, there are dozens of little-known arboviruses that usually circulate among mosquitoes, monkeys and other animals and that must be controlled, such as the Oropouche virus.

Additionally, Orduna recommended control urban vectors, reduce their contact with people, better train medical personnel, to have laboratories in the region with refined techniques of molecular biology to identify viruses in blood samples. The most important thing is "to make an early consultation when you have a fever, especially when you have been in endemic areas."
