The reports published by the CDC and the NIH of the United States confirm the claim.
According to a summary report by CDC, the immediate(short-term) health risk from coronavirus(COVID-19) is considered low in most of the American public as of 3 March 2020. The long-term, the spread of COVID-19 in parts of the United States raises the level of concern about the immediate threat of COVID-19 for those in communities.
The possibility of the public health threat posed by COVID-19 is very high in both the United States and globally because the risk assessment would change day by day.
Further, the National Institute of Health (NIH) has published a situation summary of the COVID 19, detailing the risks of a possible spread in the U.S. and the measures to be taken to control the virus. The report warns about possible overloading of the healthcare system with elevated rates of hospitalizations and deaths. It further raises concerns about the hospitals being overburdened and the negative effects that may occur to the emergency medical services countrywide.
The Washington Post in its article showcasing the concerns of the U.S, healthcare workers have highlighted concerns like the shortage of critical personnel in the healthcare system and the potential virus threat to the workers. This implies that there exists a necessity to gear the policies towards the healthcare system in the event of any clustered cases.
