People with type O blood are less likely to become infected or develop serious illnesses caused by COVID-19, says one study. Research published in the journal Annals of Internal Medicine analyzed more than 225,000 people who were tested for COVID-19 between January 15 and June 30, 2020. Scientists found that people with type O negative blood had a 2.1% chance of positive testing for coronavirus – the lowest probability among all blood groups. The highest probability was in the positive blood group B, 4.2%. Keep reading – and to ensure your health and the health of others, don’t miss these sure signs that you’ve had the coronavirus.
Blood type resulted in “slightly lower risk” of infection
The researchers found that people with blood type O had a lower chance of severe COVID disease or death compared to people with other blood types.
In addition, people with Rh negative blood were found to be less likely to have infection and serious COVID-19 disease than people with Rh positive blood.
“Blood groups O and Rh- may be associated with a slightly lower risk of SARS-CoV-2 infection and severe COVID-19 disease, “concluded the researchers.

What this means?
The results are not entirely surprising. Other peer-reviewed studies have come to the same conclusion about COVID.
And scientists have previously found that certain blood types appear to be more protective against certain diseases than others. For example, people with type O blood tend to get more cholera sick than people with other blood types.
It may be due to antigens, proteins that cover the surface of red blood cells and determine their blood type. When a virus or bacteria enters the body, these antigens activate the immune system to fight the invader. Some blood types appear to be more effective sentinels than others.
Specific to COVID-19, people with type O blood have a lower tendency to form clots in general. One of the most serious – and poorly understood – complications of COVID-19 is that, in some people, the virus causes clots to form throughout the body, which can cause heart attacks, strokes and pulmonary embolisms, some of which can be fatal.
For now, these are theories that are undergoing further study. But now, some things are clear: people with type O blood are not immune to the coronavirus. Regardless of your blood type, you must follow all public health recommendations to avoid contracting or spreading COVID-19.

How to survive this pandemic
As for you, do everything you can to avoid getting – and spreading – COVID-19 in the first place: Wear a face mask, get tested if you think you have coronavirus, avoid crowds (and bars and parties at home), practice social detachment, just perform essential tasks, wash your hands regularly, disinfect frequently touched surfaces and to overcome this pandemic in the healthiest way do not miss these 35 places you’re most likely to reach COVID.
COVID symptoms usually appear in this order, the study concludes.
You have heard of the main signs of coronavirus – dry cough, fever and more. But did you know that they usually appear in a certain order? Then says one study, published in the magazine Frontiers in Public Healthand led by experts from the Convergent Science Institute in Cancer at the USC Michelson Center. Continue reading to see the order not to miss the first signs and to overcome this pandemic in the healthiest way, do not miss these Clear signs that you have had the coronavirus.
1. Fever
Fever is a way for your body to fight disease. It is also the first sign of coronavirus. “Although a fever is technically any body temperature above the normal 98.6 F (37 C), in practice a person is generally not considered to have a significant fever until the temperature is above 100.4 F (38 C) ”, Reports MedicineNet.
2. Cough
You will probably experience this next. What does a COVID-19 cough feel and sound like? “Considering that COVID-19 irritates the 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 becomes full of fluid and you may experience even more shortness of breath as your body struggles to get enough oxygen.”
3. Muscle pain
This is likely to happen after fever and cough. “Muscle pain – often caused by muscle inflammation (myositis) – is not an uncommon symptom for a viral infection,” according to Health. “In general, coronavirus, like other viruses, can cause inflammation of muscle tissue”, Amir Barzin, DO, MS, commander of the incident for the Respiratory Diagnostic Center at the UNC Medical Center in Chapel Hill, said Leah Groth.
4. Nausea and / or vomiting
After the first three symptoms, you may experience motion sickness. “The upper gastrointestinal tract (ie, nausea / vomiting) appears to be affected before the lower gastrointestinal tract (ie, diarrhea) in COVID-19, which is the opposite of MERS and SARS,” wrote the scientists.
5. Diarrhea
This is the fifth symptom for many, say the researchers. “Diarrhea usually occurs in people with COVID-19”, reports Healthline. “A study published in the American Journal of Gastroenterology examined 206 patients with a mild case of COVID-19. They found that 48 people had only digestive symptoms and 69 others had digestive and respiratory symptoms. “RELATED:This is the number one way for you to get COVID, according to doctors
6. Why the order is important to you
“This order is especially important to know when we have overlapping cycles of illnesses like the flu that coincide with COVID-19 infections,” said scientist Peter Kuhn, who worked alongside scientist James Hicks and doctoral candidate Joseph Larsen. “Doctors can determine what steps to take to care for the patient and can prevent the patient’s condition from getting worse.”“The order of symptoms is important,” added Larsen. “Knowing that each disease progresses differently means that doctors can identify earlier if someone is likely to have COVID-19 or another disease, which can help them make better treatment decisions.” As for you, to overcome this pandemic in the healthiest way, do not miss these 35 places you’re most likely to reach COVID.
