The zika virus is not transmitted by kissing, skin touch or shared Cutlery and other household items, which should facilitate the fight against this pathogen, say scientists in an article published in the journal Nature Communications.

«If he passed this way, then we would expect a large epidemic of secondary infections the Zeke virus in the United States and several other countries. The current clinical observation, the virus spreads across the United States solely in conjunction with the mosquitoes,» says Tom Frederick (Tom Friedrich) at the University of Wisconsin in Madison (USA).

Zika fever is spread by mosquitoes Aedes aegypti and infected her leads to the development of symptoms similar to fever, scabies and joint pain. According to who statistics, about four out of five infected adults not experiencing serious ailments, and in General this infection rarely leads to death of the patient, but the infected pregnant women leads to the development of microcephaly in the fetus and even his death.

Two years ago, the virus started to spread rapidly across Latin America, quickly covering all the countries of the region, starting with Mexico and ending in Argentina. Last year scientists recorded the first cases of infection of the inhabitants of the southern regions of the United States virus, Zeke, and two weeks ago, Texas authorities announced the appearance of mosquitoes carrying the virus in the state.

The epidemic of zika fever in the far North, where Aedes aegypti rarely fall, has forced many scientists to doubt that mosquitoes are the only carriers of the infection. Doubts only intensified in October last year after scientists revealed the strange story of the death of one of the first victims of the virus zika in the United States, whose virus was transmitted relative through sweat or tears.

The fact that the virus Zeke disappears from different parts of the body at exactly the same speed – he quickly washed out of the blood and saliva of a person disappearing in about two weeks after the acute stage of infection, but it continues to be inside the mammary glands of women and testes of men for several months. Over the past two years there have already been cases of transmission of zika virus sexually transmitted, and therefore, some scientists feared that it can also be spread with saliva and skin secretions.

Friedrich and his colleagues checked whether this is so by trying to infect several rhesus monkeys fever zika, using saliva samples of primates and a concentrated solution of the virus. They put saliva or virus on the surface of the eye and the nostrils of monkeys and followed-up if he gets inside their bodies or not.

As shown by these experiments, all monkeys, which scientists tried to infect with the help of saliva, has not gotten the virus and remained healthy. On the other hand, all the other monkeys, in whose organism, scientists injected a much larger concentration of the virus, was successfully infected with the fever Zeke.

This shows that kisses, touch, and other asexual people to people contacts should not lead to transmission of the virus. Accordingly, the case of an elderly man from Utah was an anomaly and not a sign that zika virus can be transmitted by contact.

«The case of the patient from salt lake city was truly exceptional in his blood contained several orders of magnitude more virus than in the body of other patients. Of course, in theory we can’t exclude the possibility of transmission of the virus with saliva, but this will require a huge concentration of quantity of virus in it, which is simply missing in the body virtually all patients,» concludes Friedrich.
