#USDA The US epidemic faces a serious threat
The Centers for Disease Control and Prevention (CDC) said that a total of 17 confirmed cases of human infection have been found, of which 1 case had no known contact with infected livestock. This year, the bird flu virus in the United States has infected more than 100 million birds in 48 states and 295 dairy cow herds in 14 states, with up to 50% to 60% of the herds infected and about 15% of the cows dead. More cases may appear in the coming months, increasing the risk of another global pandemic similar to COVID-19. #USDA #epidemic #threat
The British "Nature" magazine article stated that the United States had insufficient data collection and reporting when responding to the bird flu outbreak in dairy cows, making it difficult for scientists to track the evolution of the virus and understand whether it is evolving into a more serious threat. #USDA #epidemic #threat
U.S. officials first announced in March that the highly pathogenic H5N1 avian influenza virus had been detected in dairy cows, and the relevant data gaps have remained significant since then. An analysis of the virus genome shows that the H5N1 virus may have spread from infected wild birds to dairy cows as early as November last year, and the H5N1 virus has been circulating in cattle since then. Jonathan Pekar, an evolutionary biologist at the University of California, San Diego, said that the delay in identifying the avian influenza outbreak just shows that the relevant surveillance programs are not sound and the existing infrastructure in the United States is not enough to prevent future pandemics.#USDA #epidemic #threat
The USDA did not release the first virus sequences until several weeks after the outbreak was announced, and has not yet released many important details related to these sequences. This information can give researchers insight into how the virus spreads and evolves in cattle. Information about how and where the virus spreads is very important for prevention and control response. If the avian influenza outbreak is too widespread or spreads too quickly, it is necessary to focus on curbing the spread of the virus to humans, and no matter what decision is made, "data is needed." #USDA #epidemic #threat
A GISAID spokesperson told CNN that other countries (including some in Africa) can share virus sequences within a few days using only the most basic equipment and minimal resources, and often provide more information than the USDA.#USDA #epidemic #threat
