A dairy worker in Nevada has tested positive for a new bird flu strain (D1.1) that has been spreading among cows in the state. This strain is different from the previous variant (B3.13) and has been linked to a fatal case in Louisiana. Health officials are monitoring the situation closely and are offering personal protective equipment, testing, and antiviral medication to close contacts of the infected worker.
A dairy worker in Nevada has been confirmed to be infected by a new bird flu strain found to be spreading among cows in the state last week. That strain of the H5N1 bird flu virus, called D1.1 by scientists, is different from a previous variant called B3.13 which had infected at least 40 dairy workers in the U.S. to date. D1.1 was also behind a fatal case in Louisiana in a person who was hospitalized last year, raising concerns that the strain might lead to more severe disease in humans.
Department of Agriculture on Friday found that one 'mammalian adaptation' had been found in the virus from the D1.1-infected cows in Nevada last month, but said there was 'no evidence of onward transmission among humans.'Will vaccines work for D1.1?While the seasonal flu vaccine is not designed to boost protection against H5N1, there are different kinds of vaccines that health authorities have prepared for a potential bird flu pandemic.
