Zika virus: WHO expects about 4 million infections and convenes emergency committee

The session aimed to inform countries of more details of the epidemic that struck Brazil and 22 other countries, with cases already confirmed. WHO Director-General Margaret Chan was present and stressed that WHO is deeply concerned about the rapid evolution of the situation for four main reasons:

The possible association of zika infection with birth of malformed infants and syndromes neurological diseases, such as microcephaly - noting that the WHO still does not accept this causal relationship due to a lack of medical evidence, of proof

  • Possible international dissemination of the virus due to the huge geographic distribution of the mosquito
  • With this, Chan called an emergency committee for next Monday, February 1, to discuss the epidemic, the relationship with neurological syndromes and what can be done internationally to minimize the problem. The director general stated that at this time the level of concern of WHO with the Zika virus is as great as the number of uncertainties we have at the moment, and that we all need quick responses. She also said that the focus should be on these. women who are pregnant or have had their babies born with some malformation, which may be related to Zika. He also pointed out that even if the person does not travel to endemic areas, he is at risk of contracting the disease, since it is transmitted by the Aedes aegypti mosquito (which also transmits dengue and chikungunya fever), which has a very large population in the The main recommendation is to control the mosquito
  • Marcos Espinal, current director of the Department of Communicable Diseases and Health Analysis of the Pan American Health Organization (PAHO), one of the experts on the subject who was heard, pointed out that the Zika virus is not the Ebola, meaning that it needs a vehicle to spread - which in this case is the Aedes Aegypti mosquito.

He stressed that it is not necessary to panic but to control the mosquito so aggressive, since local populations have never been exposed to the virus it carries and do not have immunity to fight it.

Experts also pointed out that they expect an increase in cases of Zika vir reported, and even more unreported ones, since the symptoms are usually mild and may be mistaken for some virus. Not to mention that the virus can only be detected in the tests available today in the five days following the manifestation of symptoms, which is a very small window for detection. They also asked the doctors' attention for the symptoms, since they are similar to those of dengue - which has more complications and can lead to death.

Type of bacteria present in the vagina may interfere with the possibility of HIV infection

Type of bacteria present in the vagina may interfere with the possibility of HIV infection

A study published in mBio magazine, the online journal of the American Society of Microbiology, showed that HIV particles were retained in the cervicovaginal mucus of women who have a specific type of bacteria in the vaginal region - which they compared to a kind of "biological condom." This bacterium, lactobacillus crispatus, could lead to ways to reduce transmission of the HIV virus and other sexually transmitted diseases (STDs) through vaginal sex.
