Is there anything I should not do?
The following measures ARE NOT effective against COVID-2019 and can be harmful:
Wearing multiple masks
Taking antibiotics (See question 10 “Are there any medicines of therapies that can prevent or cure COVID-19?”)
In any case, if you have fever, cough and difficulty breathing seek medical care early to reduce the risk of developing a more severe infection and be sure to share your recent travel history with your health care provider.
