Besides vaccines, there are also drug studies going on to fight COVID-19. One such medicine is called Kaletra, commonly used for HIV patients. Many other drug trials (including the antimalarial drug cholroquin) are going on.
The incubation period (the time from infection to symptoms) was also studied in Wuhan and forms the basis of the quarantine period of 14 days. The average incubation period is five days but may be up to 12 days. To be on the safe side a two-week quarantine is recommended, after which it is unlikely that the symptoms will manifest.
Unlike some western countries, China, Singapore, Taiwan, and South Korea practiced widespread contact tracing to control the disease. If someone was diagnosed with COVID-19, the health professionals took a detailed history of who their contacts (including family and friends) were, and followed up to see if they developed symptoms. Contact tracing helped stem the spread of the disease in these countries.
