An important step to understanding the dynamics of arbovirus transmission, such as dengue fever, zika and chikungunya, is to get to know mosquitoes’ ability to get infected and to transmit the viruses that cause these diseases. This characteristic is technically known as vectorial competence. A study by researchers of the Oswaldo Cruz Institute (IOC/Fiocruz) showed that the Aedes aegypti has low vectorial competence for the zika virus when...

The analysis of a historical series of 16 years (2004 to 2019) of the incidence of dengue fever in 20 countries of Central and South America has concluded that the dynamic of dengue fever occurrence in the region was changed after zika virus epidemics, possibly due to crossed immunity between the two virus, that belongs to the same family. In the study, researchers analyzed data of notified cases suspected of dengue fever, reported to the...

Researchers of Fiocruz and Visuri, reference institutions in research and development of technology for health, have developed a portable device, the OmniLAMP, for the molecular diagnosis of COVID-19 through the detection of SARS-CoV-2 genetic material. Using the RT-LAMP technique, which transforms RNA into DNA and amplifies it isothermically, the equipment makes it possible to run tests with safety levels similar to those of the PCR (polymerase...
