That’s 100,000 cases in about 3 months. So if the corona virus spreads like the regular flu and is not contained and there were 34 million cases in the USA (like the flu this year) with a mortality rate of 3% that would be over 900,000 deaths in a year. The public health system would be overwhelmed. Italy currently has over 10,000 cases in just 2 months, check out the news videos of ICU units in tents there because of not enough public health infrastructure.
Hopefully it will be contained and the spread slows down or stops while a vaccine is developed.
