Dr. Siobhán Kennelly:

We did not have information on what asymptomatic transmission looked like in Covid-19 until well into later March. One of the things that is important to highlight in terms of some of the response is that we were also beginning to learn that presentations of Covid-19 in older people were quite atypical. They did not fit the case definition that would have been put out in terms of cough, fever and shortness of breath-----
