Mr Hanks said: "To play things right, as is needed in the world right now, we were tested for the Coronavirus, and were found to be positive.
"We Hanks’ will be tested, observed, and isolated for as long as public health and safety requires.
"Not much more to it than a one-day-at-a-time approach, no?"
He added that he would keep people posted about the situation.
Coronavirus outbreak
The actor's announcement came as Donald Trump banned flights from most of Europe from entering the US for 30 days due to the coronavirus.
However, Ireland was not included in a list of affected countries released by the Trump administration.
In the Republic, 43 cases of COVID-19 have now been confirmed - after nine more were confirmed yesterday evening.
The first death in Ireland from the virus was also confirmed yesterday.
The woman died in a hospital in the east of the country. She was elderly and was suffering from an underlying medical condition.
Elsewhere, Trinity College yesterday told students that a second case had been detected in the college community.
