Fiocruz detects presence of Zika virus in saliva and urine
Study of the Oswaldo Cruz Foundation (Fiocruz) found the presence of active Zika virus (ie that can cause infection) in samples of saliva and urine. This unpublished evidence was obtained by the Laboratory of Molecular Biology of Flavivirus of Fiocruz and creates the need for an investigation of these pathways of contagion.
To reach this conclusion, samples of two patients were analyzed. Fluid collection was done on days when they had symptoms compatible with the Zika virus. They then placed the samples in contact with Vero cells, normally used in studies with flaviviruses (such as zika, dengue fever, chikungunya fever and yellow fever). The cells were destroyed or damaged, which shows viral activity. In addition, PCR confirmed the presence of genetic material from the Zika virus. The Discriminatory NAT Kit for Dengue, Zika and Chikungunya (also developed by Fiocruz) was also used and discarded the infection by the other two diseases.
"This is the first time we have demonstrated that the virus is active, ie with This leads to an important question, but the understanding of the epidemiological relevance of these potential pathways of infection demands further studies, "says Myrna Bonaldo, chief of the Laboratory and coordinator of the study.

Often, when we think of diseases in a region, we forget the role of each individual when it comes to fighting them. If the issue is a public health problem in our community, every correct attitude is worth a lot. " " A good deal of disease can be avoided or at least be at risk of being reduced by individual measures, "says the Rodrigo Lima, director of the Brazilian Society of Family and Community Medicine The epidemiologist Eduardo Hage, director of the Department of Surveillance of Transmissible Diseases (DEVIT) of the Ministry of Health, citizen participation is essential.
On a pre-carnival Saturday, a young man stands in line at the market's cashier and begins to read a package of condoms that was on the next gondola.
