New findings: Your blood group controls if you get the winter sickness
The winter sickness strikes some people, while others seem to be more or less immune. Now research shows that the blood group controls who gets sick or not.
Everyone who has suffered from the winter sickness knows that it is a near-death experience that you would rather not experience again. But unfortunately, it is not easy to protect against the fearful and highly contagious norovirus. It is unusually long-lived, and it is also difficult to kill. Only a minimal amount of virus particles, about ten pieces, is needed to infect anyone, and a handgun only has a limited effect on the virus. New findings also indicate that the virus can survive in tiny droplets in the air for many hours.
These two blood groups do best
Although the norovirus is so contagious, some people seem to be more resistant to it than others. Studies have shown that about 20 percent seem to be able to cope entirely with vomiting. They have hereditary protection against the disease thanks to a gene that prevents certain forms of norovirus from getting attached to the small intestine. But who gets sick also depends on what blood group you have, research shows :
People with blood group B more often have protection against winter malaise than people with blood group 0 and A.
The most easily infected are people with blood group 0.
Even those with blood group AB have better resistance than blood group 0.
But even though those with the blood groups B and AB can manage without getting stomach symptoms, they can still carry the virus and infect others. It is called to be asymptomatic. Also, no one has a full 100 percent protection against winter malaise. Norovirus is present in many variants and subgroups, and it can also mutate. Genetic protection applies to only 80 percent of all noroviruses. So you can get stomach upset if you come across a virus that has mutated.
How to protect yourself against norovirus
The best way to avoid getting sick is to wash your hands properly with soap and water. Wash your hands whenever you come home, been to the toilet and before handling food.
Make sure you dry your hands so that they dry properly afterward. Otherwise, the moisture can dissolve the bacteria on, for example, a handle so that you get them on your newly washed hands.
Use paper towels. Fabric towels can be full of viruses.
