Coronavirus Outbreak: Worst Still to Come in US

The coronavirus has already infected over 1,000 people and been found in about 40 US states, according to reports. At least 31 people have died from the illness in the US. 

When asked by a member of the committee if the virus is expected to spread even further, Fauci replied: "Yes, it is."  

Authorities at state and local levels have taken steps to stop the spread of the virus, including cancellations of large gatherings. Democratic presidential candidates former Vice President Joe Biden and Senator Bernie Sanders both canceled rallies in Cleveland. Washington Governor Jay Inslee on Wednesday banned gatherings of more than 250 people and said he may soon close schools to slow the spread of coronavirus. 

But community spread of the virus has outpaced these efforts, Fauci warned.

"How much worse we'll get will depend on our ability to do two things: to contain the influx of people who are infected coming from the outside, and the ability to contain and mitigate within our own country", he said. 

The US is facing a lack of testing kits for the virus, among other challenges. Centers for Disease Control and Prevention Director Dr. Robert Redfield said during the hearing that the US public health system could test about 75,000 people.  

The government will start to ban some gatherings of events and tourist restrictions.
