People with blood type O have a lower chance of becoming infected with COVID-19 or developing serious diseases, says a study. Research published in the journal Annals of Internal Medicine looked at more than 225,000 people tested for COVID-19 between January 15 and June 30, 2020. Scientists have found that people with blood group O-negative have a 2.1% chance of testing positive for coronavirus – the lowest probability among all blood groups. The highest probability was 4.2% in the blood group B-positive. Read on – and to ensure your health and the health of others, do not miss this Sure Sign you already had.
The blood type led to a slightly lower risk of infection
The researchers found that people with blood group O had a lower chance of severe COVID disease or death compared to people with other blood groups.
In addition, people with Rh-negative blood were found to have a lower probability of both infections and severe COVID-19 diseases than people with Rh-positive blood.
“The O and Rh blood groups may be associated with a slightly lower risk of SARS-CoV-2 infection and severe COVID-19 disease, ‘the researchers concluded.

What does it mean?
The results are not entirely surprising. Other peer-reviewed studies have reached the same conclusion about COVID.
And scientists have previously found that certain blood groups appear more protective against certain diseases than others. For example, people with type O blood are more likely to get cholera than people with other blood types.
This may be due to antigens, proteins that cover the surface of red blood cells and determine your blood type. When a virus or bacterium enters the body, those antigens cause the immune system to fight the invader. Some blood types seem more effective than others.
Specifically for COVID-19, people with type O blood have a lower tendency to form blood clots. One of the most serious – and poorly understood – complications of COVID-19 is that in some people the virus causes it to clot in the body. It can cause heart attacks, strokes and pulmonary embolisms, some of which can be fatal.
For now, these are theories that are being studied further. But at the moment, a few things are clear: people with type O blood are not immune to the coronavirus. No matter what your blood type, you should follow all public health recommendations to avoid contracting or spreading COVID-19.

How to survive this pandemic
As for yourself, do everything you can to prevent and spread COVID-19 in the first place: Wear a face mask, is tested if you think you have a coronavirus, avoid crowds (and pubs and house parties), do social distances, perform only essential tasks, wash your hands regularly, disinfect surfaces, and get through this pandemic in your healthiest place , do not miss this 35 places you are likely to catch COVID.
COVID symptoms usually appear in this order
You have heard of the most important signs of coronavirus – dry cough, fever and more. But did you know that it usually appears in a certain order? So say a study, published in the journal Boundaries in public health, and led by experts from the USC Michelson Center’s Convergent Science Institute in Cancer. Read on to see the sequence so you do not miss the first signs, and to get through this pandemic in your healthiest way, do not miss it Sure signs that you already have Coronavirus.
1. Fever
Fever is one way your body can fight disease. It is also the first sign of coronavirus. “Although fever is technically any body temperature higher than the normal temperature of 37 ° C, in practice a person is not usually considered a significant fever if the temperature is above 38 ° C,” MedicineNet reports.
2. Cough
You will probably experience this next. How does a COVID-19 cough feel and sound? “As COVID-19 irritates lung tissue, the cough is dry and persistent. It is accompanied by shortness of breath and muscle pain,” reports ScienceAlert. “As the disease progresses, the lung tissue fills with fluid and you may still feel short of breath if your body struggles to get enough oxygen.”
Muscle aches
It will probably occur after the fever and the cough. “Muscle pain – often caused by myositis – is not an uncommon symptom of a viral infection,” he said. Health. “In general, coronavirus, like other viruses, can cause inflammation in muscle tissue.” Amir Barzin, DO, MS, said the incident leader for the Respiratory Diagnostic Center at the UNC Medical Center in Chapel Hill, Leah Groth said.
4. Nausea and / or vomiting
After the first three symptoms, your stomach may feel full. “It seems that the upper GIT (ie nausea / vomiting) is affected before the lower GIT (diarrhea) in COVID-19, which is the opposite of MERS and SARS,” the scientists wrote.
5. Diarrhea
This is the fifth symptom for many, the researchers say. “Diarrhea usually occurs in people with COVID-19,” reports Health line. “One study published in the American Journal of Gastroenterology 206 patients examined with a mild case of COVID-19. They found that 48 people had only digestive symptoms and another 69 had digestive and respiratory symptoms. ‘RELATED:According to doctors, this is the best way to get COVID
6. Why the order matters to you
“This sequence is especially important to know when we have overlapping cycles of diseases such as influenza that coincide with COVID-19 infections,” said scientist Peter Kuhn, who worked with scientist James Hicks and doctoral student Joseph Larsen. “Physicians can determine what steps to take to care for the patient, and it can prevent the patient’s condition from deteriorating.”“The order of the symptoms is important,” Larsen added. “Knowing that each disease is different means that doctors can more quickly determine if someone is likely to have COVID-19, or another disease, which can help them make better treatment decisions.” As for yourself, do not miss this to get through this pandemic in your healthiest way 35 places you are likely to catch COVID.
