The successes in response to COVID-19 threats have come not just from scientific cognition of disease characteristics (SARS-CoV-2) strain biological characteristics, disease prognosis, etc., but also from broad approaches that play a complementary role to fight against COVID-19, including constant surveillance of SARS-CoV-2 strain, clinical and public health efforts, and efficient translation of new findings into disease-control application and implementation.
The comprehensive strategies and measures are formulated based on four elements : (1) SARS-CoV-2 strain characteristics include infectivity, pathogenicity, and mutations. (2) Social and economic development situation, including demographic characteristics, medical resource, material supply, etc. (3) Culture, scientific and technological level. (4) Government will, prevention and control concept, social system and social mobilization capacity.
