I have seen it as well. The virus has mutated more than once, so there are different varieties. Also, at this time, IF you have any immunity, they believe it will only last for about 2 months. It will be interesting to see when vaccines come out if they will actually be more like the Influenza Vaccine where it needs to be given annually and changed every year.
