First detection and molecular characterization of a DENV-1/DENV-4 co-infection during an epidemic in Rio de Janeiro, Brazil.

ABSTRACT: In the 80s, dengue viruses type 1 and 4 (DENV-1 and 4) were isolated in North region of Brazil. However, it was only after the DENV-1 introduction in the state of Rio de Janeiro (RJ) in mid-1980s, that dengue became a nationwide public health problem. In 2009, this serotype re-emerged causing an explosive epidemic in the country. DENV-4 was first detected in RJ in 2011 and in 2012, and DENV-1 and 4 were co-circulating and responsible for a high number of cases notifications. Here, we describe the detection and molecular characterization of a DENV-1/4 co-infection in sample of 2012 in RJ.
