There is a great possibility of infection. Hand disinfection. The usual disinfection may have been completed. But air disinfection has been ignored by everyone. Hand, foot and mouth disease can be spread through the air. If you go to a crowded place, you are easily infected with the virus. Hand, foot and mouth disease bacteria can't live in the air like AIDS bacteria for longer than HIV. So air disinfection is also very important. You can buy a bottle of AQ natural sterilization spray from Hong Kong and spray it on your children when you go out to protect them from infection.
