About 30% of COVID-19 deaths are due to blood clotting, but the main reason for deaths due to the virus is respiratory failure.
However, multiple studies have found that a COVID-19 infected person has severe difficulty in breathing, resulting in most of the deaths. Older adults and those with underlying medical conditions are more susceptible to death due to respiratory failure. The death rate due to COVID-19 is between 2 and 7 percent among the infected, with most cases requiring respiratory aid before they succumb to the viral infection. Therefore, it indicates that respiratory failure has caused the majority of deaths during the pandemic.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
