PM Shinzo Abe says the Tokyo Games will go ahead (of course this could still change but it appears the virus has shifted from Asia to Europe now):

IndyCar races have been suspended until the end of April (with Long Beach having been cancelled earlier already).
Of course month of May is the peak of IndyCar with Indianapolis 500 scheduled on the last Sunday of the month. Even the Spanish flu in 1918-19 didn't force Indy 500 to be held outside of May!
Paulina Fialkova finished 77th today. It's not like she would be starting in the pursuit anyway The rest of the Slovakian team, well, they have nothing to compete for anymore either.
This makes sense. If there's a visible decline in China/Korea come the end of April we could establish the outbreak will be in decline elsewhere too. Things could be back to normal in Japan come July.
