Brazil will develop test to detect Zika virus in blood for donation

Ministry of Health intends to include the Zika virus in the NAT test, DNA test currently used to detect HIV and hepatitis B virus and hepatitis C in blood bags donated in national blood centers. The development of the new NAT test will be done by the Biomanguinhos Laboratory of the Oswaldo Cruz Foundation (Fiocruz), in Rio de Janeiro, already the creators of the previous test.

The action will count on the support of the United States to give faster (ANVISA) with the FDA (US Food and Drug Administration, which regulates new drugs, tests and food).

The agreement was signed after the Meeting Bilateral Brazil-USA Strengthening Cooperation for Response to the Zika Virus Epidemic, which occurred last Friday (19). In addition to this collaboration, a committee will be formed to give continuity in the development of research for diagnosis, control, vaccine and treatment against the Zika virus.

Transmission by blood in the target of the scholars

For some time the Zika transmission cases viruses are being observed by Brazilian authorities. For the time being, two cases of blood transfusion transmission of the Zika virus were confirmed at the Hemocentro of the State University of Campinas (Unicamp), but none of the patients presented symptoms.

So much so that a project of the Pró-Sangue / Hemocentro Foundation Paulo, supported by the Foundation for Research Support of the State of São Paulo (FAPESP), has already been able to develop a method that detects the presence of Zika virus in the blood used in transfusions.

The idea is to use this method in screening blood that will be used in pregnant women or intrauterine transfusions (ie where the blood is transferred directly to the fetus). That equates to about 0.16% of the blood bank's stock. The technique has already begun to be used in the Hemocentro of São Paulo after the Carnival
