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 This unpublished evidence was obtained by the Laboratory of Molecular Biology of Flavivirus of Fiocruz and creates the need for an investigation of these pathways of contagion.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.
