GENEVA (AP) — The World Health Organization has an unwelcome but potentially life-saving message for the holiday season: Don't hug.
To stop the spread of the coronavirus, WHO's emergencies chief said Monday that the “shocking” rate of COVID-19 cases and deaths, particularly in the U.S., means that people shouldn't get too close to their loved ones this year.
Brazil’s health ministry is studying 58 suspected cases of Covid-19 re-infection after confirming the first case of a person getting re-infected with coronavirus, a ministry spokeswoman said.
The first case was a health worker in the northern city of Natal, a 37-year-old woman, who tested positive in June and again 116 days later in October, the ministry said on Thursday.
The re-infection was confirmed by the FioCruz biomedical research center in Rio de Janeiro, it said in a statement.
So far 58 suspected cases of re-infection have been reported and are being studied, the spokeswoman said.
The cases involve people who tested positive and their re-infection must be confirmed as a separate infection and not the re-appearance of the same infection, she said.
The FioCruz researcher who did the genetic sequencing of the infection of the case in Natal, Paola Resende, said it looked like the woman did not generate enough anti-bodies to avoid getting infected again more than 90 days later.
Resende told Reuters that the woman was infected by a separate strain of coronavirus the second time.
"The pathogen of the sample collected in June belonged to the B.1.1.33 strain and the October sample was from the B.1.1.28 strain. Both had already been detected in Brazil,” she said.
Scientists have linked the most severe form of COVID-19 with five genes that affect lung inflammation and the body’s ability to fight off viruses.
Their findings, from a study of 2,700 COVID-19 patients in intensive care units across Britain, point to several existing drugs that could be repurposed to treat people who risk becoming critically ill.
The genes - called IFNAR2, TYK2, OAS1, DPP9 and CCR2 - partially explain why some people become desperately sick with COVID-19, while others are not affected, said Kenneth Baillie of Edinburgh University, coauthor of the study published on Friday in Nature. The new information should help scientists design clinical trials of medicines that target specific antiviral and anti-inflammatory pathways. Among those with the most potential, Baillie said, should be a class of anti-inflammatory drugs called JAK inhibitors, including Eli Lilly’s arthritis drug baricitinib, which has been found to help hospitalized pneumonia patients in combination with Gilead’s remdesivir.
