Economic Burden of Public Health Care Was Higher than that of Hospitalization and Treatment Associated with COVID-19 In China (preprint)

Background: During the coronavirus disease 2019 (COVID-19) pandemic, it is essential to evaluate the socioeconomic burden imposed on the Chinese health care system.Methods: We prospectively collected information from the Center for Disease Control and Prevention and the designated hospitals to determine the cost of public health care and hospitalization due to COVID-19. We estimated the resource use and direct medical costs per confirmed case and the costs associated with public health care per thousand people at the national level.Findings: The average costs per case for specimen collection and nucleic acid testing (NAT) were $29.49 and $53.44, respectively, while the average cost of NAT for high-risk populations was $297.94 per capita. The average costs per thousand people for epidemiological surveys, disinfectant, health education and centralized isolation were $49.54, $247.01, $90.22 and $543.72, respectively. A single hospitalization for COVID-19 in China cost an average of $3,792.69 ($2,754.82-$5,393.76) in direct medical costs incurred only during hospitalization, while the total costs associated with hospitalization were estimated to have reached nearly $31,229.39 million in China as of 20 May 2020. The cost of public health care ($6.81 billion) was 20 times that of hospitalization. Interpretation: This study highlights the magnitude of resources needed to control the COVID-19 pandemic and treat COVID-19 cases. Public health measures implemented by the Chinese government have been valuable with regard to reducing the infection rate and may be cost-effective ways to control emerging infectious diseases.

Relationship between the ABO Blood Group and the COVID-19 Susceptibility (preprint)

The novel coronavirus disease-2019 (COVID-19) has been spreading around the world rapidly and declared as a pandemic by WHO. Here, we compared the ABO blood group distribution in 2,173 patients with COVID-19 confirmed by SARS-CoV-2 test from three hospitals in Wuhan and Shenzhen, China with that in normal people from the corresponding regions. The results showed that blood group A was associated with a higher risk for acquiring COVID-19 compared with non-A blood groups, whereas blood group O was associated with a lower risk for the infection compared with non-O blood groups. This is the first observation of an association between the ABO blood type and COVID-19. It should be emphasized, however, that this is an early study with limitations. It would be premature to use this study to guide clinical practice at this time, but it should encourage further investigation of the relationship between the ABO blood group and the COVID-19 susceptibility.
