A study published on Tuesday in PLoS Medicine suggests that boosting vitamin D levels with supplements would not help. Researchers studied more than 1.2 million people of European ancestry from 11 countries, some of whom had genetic variants that result in naturally higher levels of vitamin D. People with these variants did not have a lower risk for coronavirus infection, hospitalization, or severe COVID-19, the researchers reported. Infection risk was highest for spouses, followed by non-spouse family members and other relatives, which were all higher than other contacts, the researchers found. Overall, they estimated the household secondary attack rate was 16.6%. A new NIH study found that only 0.001% of blood samples from donors to recipients contained trace coronavirus DNA (file image)An estimated 6.8 million Americans give blood every year, according to the American Red Cross, with someone in the U.S. needing blood or platelets every two seconds.
The average American would have 128.16 ml of blood.
