The Secretary of State for Public Health (SESPA) in Pará state, Brazil, is reporting eight confirmed Mayaro virus cases last year.
In Pará, the period of greatest transmission of these diseases occurs during the winter. Mayaro virus is transmitted by mosquitoes, through the bites of Haemagogus janthinomys, which also transmits yellow fever.
Of the eight cases of Mayaro fever confirmed last year, two of them were registered in Benevides and six in Igarapé Miri.
Mayaro virus — which can cause fever, joint aches, muscle pains, headache, eye pain, rash, nausea, vomiting and diarrhea — first was isolated from the blood of five symptomatic workers in Mayaro County, Trinidad, in 1954. Since then, it has caused sporadic outbreaks and small epidemics in several South and Central American countries.
Because the symptoms of Mayaro infection are similar to those caused by other arboviruses such as dengue and chikungunya, its prevalence in areas where these other viruses circulate may be higher than reported.
