Latest News Updates of Coronavirus Outbreak
Recent studies with respect to Coronavirus are bringing new highlights and developments. The scientists of China have claimed that People with blood type A may be more susceptible to infection by the new coronavirus, while those with blood group type O seems more resistant. Though there is no case study reported on it, but on the basis of speculation of the preliminary study of patients in China infected with Coronavirus the disease known as Covid-19.
In China medical researchers had taken blood group patterns of more than 2,000 patients infected with the virus in Wuhan and Shenzhen and compared them to local healthy populations. They found that blood “type A” patients showed a higher rate of infection and they had a tendency to develop more severe symptoms.
The researchers still have conveyed that the study is very preliminary and more work is needed to be done, they requested governments and medical facilities to consider blood type differences when planning mitigation measures or treating patients with the virus, known as Sars-CoV-2.

The researchers of Wang Xinghuan with the Centre for Evidence-Based and Translational Medicine at Zhongnan Hospital of Wuhan University revealed that people of blood group A might need to take extra care and also strengthen their personal protection to reduce the chances of infection.
Just opposite is with people having blood group O, who had a significantly lower risk for the infectious disease compared with other blood groups, this is revealed according to a paper published on Medrxiv.org on March 11, 2020.
In Wuhan, 206 patients who had died from Covid-19, 85 had ‘type A’ blood, which was 63 per cent more than with type O. This pattern existed across different age and gender groups.
Further, it is said that, with such type of statistics, it might be helpful to introduce ABO blood, in both patients and medical personnel as a routine part of the management of Sars-CoV-2 and other coronavirus infections, to help in the management and assess risk exposure levels of people.
Health Tips on Coronavirus 2 Limitations of the Study in the Coronavirus Crisis
The blood group comparison study was conducted by scientists and doctors from cities across China including Beijing, Wuhan, Shanghai and Shenzhen. A researcher Gao Yingdai, with the State Key Laboratory of Experimental Haematology in Tianjin said it could be improved with a larger sample size. Though, 2,000 infected patients were not small, but if compared with the total number of patients infected by the coronavirus, at nearly 180,000 globally it gets dwarfed.
Gao said there was another limitation of the study, it did not provide a clear explanation about the phenomenon, such as the molecular interaction between the virus and different types of red blood cells.
The blood types are determined by a so-called antigen, a material on the surface of red blood cells that can trigger an immune response. Karl Landsteiner, Austrian biologist discovered the main blood groups in 1901, naming them type A, B, AB and O. This discovery helped a lot for safe blood transfusions by harmonizing blood types in patients.
Blood types vary in a population. In the United States, about 44 per cent of the population is type O, while about 41 per cent is type A. In Wuhan, which has a population of about 11 million, type O is 32 per cent, while A is 34 per cent among healthy people. Among Covid-19 patients, it was about 38 and 25 per cent.

Though, scientists are not very sure with respect to response on different blood groups, but one theory is that they are a genetic memory of plagues. Other scientists also argue that environmental factors such as altitude, temperature or humidity might be playing a great role to favour the increase of certain blood type populations.
Blood group difference has been observed in other infectious diseases also, like- Norwalk virus, hepatitis B and severe acute respiratory syndrome (SARS), revealed in previous studies.
The approach to new study might be helpful to medical professionals said by Gao at the Tianjin lab. But ordinary citizens should not take the statistics too seriously. It doesn’t mean if one is with type A will lose hope, there is no need to be panic about. It does not mean one will be infected 100 per cent. If one is with type O, it does not mean they are absolutely safe, either.
One still needs to wash their hands and follow the guidelines issued by authorities.
