The spread of the new coronavirus has been compared to influenza, which also causes a respiratory illness. But, as the panelists pointed out, there are no drugs or vaccines yet for treating or preventing the virus, known as SARS-CoV-2, as there are for flu. In addition, we are exposed to different flu strains throughout our lives, which help us build immunity. No one had immunity to this new virus.
“We have an entirely susceptible population,” Mina said. “The potential for this to burn through a population very quickly is very high without extraordinary measures.”
As researchers race to study the virus, they are finding that it does not seem to be infecting great numbers of children, or at least making them very sick. (Experts around the globe are still trying to figure out just how broadly the infection has spread, given that many mild cases are likely to be missed.) But it is causing serious harm to older people and those with underlying diseases or weakened immune systems.
“This virus, on the one hand, there’s a saving grace that it doesn’t seem to be impacting our young, and that is amazing,” Mina said. “But the mortality rate among people who are getting infected above 80 years old is 15-plus%.”
If you plan for the disruptions that the response to the pandemic could require, it will seem less unexpected when schools are canceled or you’re told to work from home, advised panelist Juliette Kayyem, the faculty chair of the Kennedy School’s homeland security program and a former homeland security official at the state and federal level.
