Is there anything I should not do?

The following measures ARE NOT effective against COVID-2019 and can be harmful:

• Smoking
• 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.
