![]() The head of China's National Health Commission, Ma Xiaowei, confidentially provided a "grim" situation assessment to key Chinese health officials. The WHO also tweeted that "preliminary investigations conducted by the Chinese authorities have found no clear evidence of human-to-human transmission of the novel #coronavirus (2019-nCoV)". The WHO recommended countries to take precautions due to the human-to-human transmission during earlier SARS and MERS outbreaks. ![]() On January 14, the WHO held a press briefing stating that their information suggested a possibility of limited, but not sustained, human-to-human transmission. On January 11, the CDC updated the January 6 Level 1 travel health notice for Wuhan, China. By this date, the WHO warned of the risk of human-to-human transmission. On January 10, the WHO issued a comprehensive package of guidance to countries on how to test for potential cases. On January 9, the WHO issued a statement naming the disease as a new coronavirus in Wuhan. On January 8, the CDC issued its first public alert about the coronavirus. On January 7, the CDC established a coronavirus incident management system to better share and respond to information about the virus. Fauci, Director of the National Institute of Allergy and Infectious Diseases. ĭuring the week of January 6, officials of the Department of Health and Human Services (HHS) convened an intra-agency task force including Redfield (CDC), Azar (HHS), and Anthony S. China did release genetic data on the new coronavirus on January 9. access to the virus, important for developing diagnostic tests and a vaccine. ![]() China did not accept the offer for several weeks, which delayed the U.S. On January 6, the CDC issued a travel notice for the city of Wuhan in Hubei province, China, and CDC Director Redfield offered in a letter to Chinese officials to send a team of CDC scientists to assist China. The WHO advised against travel or trade restrictions at the time. On January 5, the World Health Organization (WHO) reported a "pneumonia of unknown cause" in Wuhan. On January 3, Redfield emailed and spoke to George Gao, director of the Chinese CDC, and the following day, January 4, emailed an offer of technical assistance. According to The Washington Post, warnings about the virus were included in the President's Daily Brief in early January, an indicator of the emphasis placed on the virus by the intelligence community. All lineages currently circulating are classified as part of the Omicron variant.On January 3, CDC Director Robert Redfield was notified by a counterpart in China that a "mysterious respiratory illness was spreading in Wuhan " he notified HHS Secretary Alex Azar, who shared the report with the National Security Council (NSC). SARS-CoV-2 lineages with similar characteristics may affect how fast the virus spreads, the severity of illness it causes, or the effectiveness of treatments against it some of these may be classified by the World Health Organization (WHO) or the U.S. All lineages have names to help scientists talk about them. ![]() The SARS-CoV-2 virus can be mapped out similar to a family tree. As genetic changes happen over time, the virus that causes COVID-19 begins to form genetic lineages. What You Need to Know About Variants | View Transcript Īs a virus spreads, it has a chance to change. Those variants must be monitored more carefully. Some variations allow the virus to spread more easily or make it resistant to treatments or vaccines. These small differences, or variants, have been studied and identified since the beginning of the pandemic. By comparing the branches, scientists can label them according to the differences. If you think about a virus like a tree growing and branching out, each branch on the tree is slightly different than the others. ![]()
