New tests can detect Zika virus in semen
Some Brazilian laboratories have started to make tests that can detect Zika virus in man's semen. There were already tests that could find the virus in the blood, urine, saliva and amniotic fluid. The tests use PCR technology, which locates parts of the virus in the liquid.
Such a measurement is important as it is not yet known whether the virus in the semen can pass the disease to partners. So far, all cases in which sexual transmission of the Zika virus is suspected are in women who have had relationship with men who were with the disease or were in places of active circulation of the Zika virus.
"It is not yet known what can happen if a baby is fertilized in a relationship where the man's semen is infected with the Zika virus, "explains geneticist Ciro Martinhago of the Chromosome Genomic Medicine laboratory, one of the first to offer this test. However, Anvisa has demanded that couples who want to undergo fertilization procedures take the Zika virus before, even egg and sperm donors.
Since people can have the Zika virus without presenting symptoms, it is important that all husbands of women who are pregnant or want to get pregnant take the test, says the specialist. There is also a recommendation for condom use by couples in whom the woman is pregnant to ensure that there is no virus infection during pregnancy.
According to Chan, the Brazilian government is doing his part in combating the Zika virus and the Aedes aegypti mosquito. But she stressed that the population should mobilize. "Every family, every member of society, has a role to play in combating the mosquito." The WHO Director-General stressed that another important part of the government is working with WHO is the research and development area so that means of diagnosis, treatment and control of the vector can be obtained.
Cases of superbugs have become increasingly common. But when the over-resistant bacterium transmits a disease that is already our old name? This is the case of gonorrhea: the World Health Organization has already issued a warning about the appearance of a type of antibiotic-resistant gonorrhea. However, last week (29th) the UK Health Service (NHS) announced the "most serious" case ever detected in the world of this supergonorrhea.
