The WHO said its new interim recommendations for preventing the sexual spread of Zika virus reflect the latest scientific evidence.
Kamran Khan, MD, MPH from St. Michael’s Hospital’s Li Ka Shing Knowledge Institute in Toronto, said, “It’s a sobering number that highlights the potential magnitude of Zika virus”. There was a first documented case of a man catching the virus through anal sex in February 2016 and a suspicion of Zika transmission through oral sex in April.
But because of the risk of microcephaly, World Health Organization says men and women returning from areas where Zika infections are ongoing are “advised to wait at least six months before trying to conceive to ensure that possible virus infection has cleared”.
Even if further studies find that Zika can not be transmitted through human tears, it may be possible to test tears for Zika genetic material or antibodies to offer a less painful way to diagnose recent Zika infection than the current method of taking blood samples, the researchers said. He said the CDC will update its guidance when the review is complete.
Iloilo City – The 45-year-old married woman who tested positive with the Zika virus has fully recuperated, the Department of Health reported yesterday.
The first case of the Zika virus was found in Knox County, Tenn., in July when a person recently returned from a Zika-infected country, according to the Knox County Health Department.
This study has also helped explain why around a third of all babies born with Zika have eye diseases.
“Even though we didn’t find live virus in mouse tears, that doesn’t mean that it couldn’t be infectious in humans”, said study lead author Dr. Jonathan Miner, an instructor in medicine. One possibility is that it crosses “the blood-retina barrier that separates the eye from the bloodstream, traveling along the optic nerve that connects the brain and the eye”, researchers said in a statement. The researchers are planning similar research in people who have been infected with Zika.
Culex is 20 times more common than the Aedes aegypti mosquito, which is the main spreader of Zika.
The important question of whether Zika found in the human eye is infectious, through tears or any other medium, needs to be determined through further study.
Sexual transmission had initially been thought to be relatively rare. This news story is related to Latest/148444-Zika-virus-found-in-tears-of-mice-US-study/ – breaking news, latest news, pakistan ne.
The majority of cases, 106, are associated with travel to the Caribbean, according to the figures from Public Health England.
Ubial said the woman has no record of traveling overseas recently to any affected countries. An additional four cases were reported, where the victims of the virus were foreigners. The other six cases have no known links to any existing cluster.
Florida officials said Tuesday they have diagnosed seven more home-grown Zika cases in Florida, six of them linked to an outbreak in Miami Beach.
Singapore last month narrowed its economic growth forecast to 1-2 percent from a 1-3 percent growth range previously expected, citing concerns over Brexit and weakening global demand. The researchers noted that follow-up will determine if the lesions have any impact on neurodevelopment. Health officials said they are increasing mosquito control efforts and are asking people to take precautions, such as emptying mosquito breeding sites.

Sexual transmission of Zika had been reported in 11 countries by August 26, mainly through vaginal intercourse.
