there is so little understanding about viruses when it comes to the general public. We are exposed everyday to viruses that if they some how over whelmed are body defenses would kill. they dont becouse we encounter them in such low amounts they are unable to do anything against the immune system. generally when we catch something it becouse we encounter a viral lode that over whelms the defenses of the body....telling some one to hide indoors away from the sun just makes a smaller exposure more dangerous.....this is my uneducated assessment and I admit that I might be one of the uneducated with this assessment.
