COVID-19, risks and risk factors for COVID-19 infection, transmission of COVID-19


At present, the situation of COVID-19 has led to the increasing number of infected patients dramatically every day. One of the reasons of the continual outbreak of COVID-19 around the world is still do not have enough information about the risks, risk factors for infection and transmission of COVID-19. Therefore, this study has the objectives to review and consolidate researches on the risks and risk factors for infection and transmission of COVID-19 in order to obtain adequate information about prevention, infection control and transmission of COVID-19 more effectively. The study was conducted by data from two medical databases, namely PubMed and Google Scholar, during 1 October 2019 - 31 March 2021. The findings indicate that the risk factors for COVID-19 infection included personal factors and external factors. The risk factors could be divided into 2 groups including risk factors of acquire infection and risk factors of becoming severe case. The risk factors of acquire infection were pregnant women, age, obesity, congenital diseases, those with alcohol drinking disorder, some genes race, occupations, daily behavior, presence of suspicious COVID-19 symptoms, air pollution and some drugs. The risk factors of becoming severe case were the elderly, obesity, congenital diseases and air pollution.
