Corona virus and kids

I know this corona virus has been pretty scary to hear about on the news recently. Having a child who constantly puts their finger in their mouth to suck their thumb/finger makes things a bit more difficult at keeping them healthy. The corona virus spreads easily and officials have said that washing your hands often or using alcohol-based hand sanitizer will help avoid infection. At first, I heard children could be immune to the corona virus, but upon further research I found that it is possible for kids to get the virus, but it is relatively uncommon. I’m still being cautious but this news has really put me at ease knowing I don’t have to be as scared for my kids to get this virus.
