Most Americans say they are concerned that there will be a major outbreak of the coronavirus in the U.S. (55%) and that it will negatively affect the U.S. economy (57%), says the latest KFF tracking poll. A substantial share (43%) also say they are concerned that they or a family member will contract the virus.

The poll finds most Americans (83%) have read or heard at least some about the coronavirus outbreak that started in December in Wuhan province in China and has since spread to other countries, with dozens of confirmed cases so far in the U.S. A similar majority (87%) are aware there have been cases diagnosed in the U.S.

So far, nearly seven in 10 Americans (69%) say that U.S. government officials are “doing enough” to prevent the spread of coronavirus. This includes majorities of Republicans (80%), independents (70%) and Democrats (60%).

“The public largely seems comfortable with the government’s response so far, but those perceptions could change if we see more U.S. cases and deaths,” said KFF Senior Vice President Jen Kates.
