The US Center for Disease Control and Prevention (CDC) has warned that the coronavirus outbreak could cause “severe disruption” to the lives of ordinary Americans, and urged families and communities to start making preparations.

The extent of the spread of the virus in the US is uncertain, as the CDC stopped the distribution of coronavirus testing kits after they were found to be flawed. Working testing kits are now available in only a handful of states, and it is not clear when new kits will be ready.

Donald Trump told journalists in India on Tuesday that coronavirus is “very well under control in our country” and “is going to go away”.

The World Health Organization is recommending that people take simple precautions to reduce exposure to and transmission of the Wuhan coronavirus, for which there is no specific cure or vaccine.

The UN agency advises people to:

  • Frequently wash their hands with an alcohol-based hand rub or warm water and soap
  • Cover their mouth and nose with a flexed elbow or tissue when sneezing or coughing
  • Avoid close contact with anyone who has a fever or cough
  • Seek early medical help if they have a fever, cough and difficulty breathing, and share their travel history with healthcare providers
  • Avoid direct, unprotected contact with live animals and surfaces in contact with animals when visiting live markets in affected areas
  • Avoid eating raw or undercooked animal products and exercise care when handling raw meat, milk or animal organs to avoid cross-contamination with uncooked foods.

Despite a surge in sales of face masks in the aftermath of the outbreak of the coronavirus outbreak, experts are divided over whether they can prevent transmission and infection. There is some evidence to suggest that masks can help prevent hand-to-mouth transmissions, given the large number of times people touch their faces. The consensus appears to be that wearing a mask can limit – but not eliminate – the risks, provided they are used correctly.

The Foreign and Commonwealth Office has advised UK nationals to leave China where possible. It is also warning that travellers from Hong Kong, Japan, Macau, Malaysia, Republic of Korea, Singapore, Taiwan and Thailand who develop symptoms of cough or fever or shortness of breath within 14 days of returning the UK should contact the NHS by phone.

However, the head of immunization at the CDC, Nancy Messonnier, said that disruption to everyday life may be severe as the virus spreads among local communities.

“As more and more countries experience community spread, successful containment at our borders becomes harder and harder,” Messonnier said in a telephone press briefing.

“Ultimately, we expect we will see community spread in this country. It’s not so much a question of if this will happen any more, but rather more exactly when this will happen, and how many people in this country will have severe illness.”

In the absence of a vaccine or medicines, other methods would be needed to contain the spread of the disease, including possible school closures, and telecommuting where possible instead of travelling to workplaces.

“I understand this whole situation may seem overwhelming, and that disruption to everyday life may be severe. But these are things that people need to start thinking about now,” Messonier said. “I had a conversation with my family over breakfast this morning, and I told my children that – while I didn’t think they were at risk – right now, we as a family, need to be preparing for significant disruption of our lives.”

The CDC acknowledged that the test kits it began distributing to state authorities earlier this month have been found to be faulty. The agency said in a statement that “performance issues were identified related to a problem in the manufacturing of one of the reagents which led to laboratories not being able to verify the test performance”.

Messonier said that 12 “states and localities” had working test kits, but according to independent health experts, that overall number includes only five states.

“I am frustrated like I know many of you are that we have had issues with our kit, and I want to assure you that we are working to modify the kit and hope to hand out a new version to state or local jurisdictions soon,” she said, adding ,“We are working as fast as we can”.

So far, 14 coronavirus cases have been identified so far in the US, including 12 travellers returning from abroad, and two patients who had contact with those returning travellers.

In addition, 40 Americans who tested positive on the Diamond Princess cruise ship have been repatriated, and three repatriated from China.
