CDC Director Warns More Coronavirus Cases Expected in US

The US Centres for Disease Control and Prevention (CDC) on Monday announced a second case of transmission of the new coronavirus within the United States and provided more detailed plans on how it will handle travellers returning from China as the country works to limit the outbreak.

All except one patient have travel history to Wuhan, China, the outbreak's epicenter, Nancy Messonnier, the USA health body's respiratory disease director, told reporters on a conference call.

The US Department of Health and Human Services (HHS) is making almost US$250 million in emergency funds available to cover the cost of the response, an agency spokesman said on Monday.

Since late December, 361 people have died and another 17,200 people have become sick from novel coronavirus in China, the World Health Organization reported Monday.

So far, the CDC has confirmed 11 cases of coronavirus within the United States, and 167 under investigation have tested negative, with tests for 82 people pending. "This is a major public health issue and we basically just need the best public health people we have in the world working on this". He transmitted the illness to his wife, also 57, following his return to the U.S.

Foreign nationals who visited mainland China in the prior 14 days, excluding immediate family of USA citizens and legal permanent residents. They will be subject to medical quarantine for up to two weeks.

US personnel could aid China in answering critical public health questions about how the virus spreads, its incubation period, and if it can be spread by those not yet showing symptoms, CDC Director Robert Redfield said.

USA citizens who traveled to the rest of mainland China within that time frame will be required to undergo additional screening and submit to "14 days of monitored self-quarantine to ensure they've not contracted the virus and do not pose a public health risk", Health and Human Services Secretary Alex Azar announced last Friday.

These measures are going into effect after the US placed 195 USA citizens under federal quarantine on March Air Force Base in Southern California last week. All people had been airlifted from Wuhan, China, and are now under a 14-day period where medical staff regularly check their temperature for fever and monitor their symptoms for cough and lower respiratory infection.

Japan, South Korea, U.S., Australia, Pakistan, India, France, Germany, Indonesia, and Turkey evacuated their citizens from Wuhan, the epicenter of the deadly virus.

"Strong measures now may blunt the impact of this virus on the United States", she said.

Cover mouth and nose with a tissue or your sleeve (not hands) when coughing or sneezing. While Messonnier did not provide additional details, a Sunday news release from the San Benito County Health and Human Services Agency said the husband, 57, had recently traveled to Wuhan, the epicenter of the outbreak.
