Type 1 or type 2 diabetes can increase your risk of serious COVID-19 symptoms. Having a higher body mass index that's considered overweight, obese or severely obese also increases this risk. Diabetes and obesity both reduce how well a person's immune system works. Diabetes increases the risk of infections in general.
Like adults, children with obesity, diabetes, asthma or chronic lung disease, sickle cell disease, or who are immunocompromised can also be at increased risk for getting very sick from COVID-19. Check out COVID-19 Vaccines for Children and Teens for more information on vaccination information for children.
People with chronic health conditions or weakened immune systems are at greater risk of more serious illness if they get COVID-19. It's important to do everything you can to protect yourself and others from COVID-19.
COVID-19 is often more severe in people 60+yrs or with health conditions like lung or heart disease, diabetes or conditions that affect their immune system. Do your part to protect those who are at most risk.
Research expands. Such findings have spurred the study of people who appear to have stayed free of COVID-19 despite high risks, such as repeated exposures and weak immune systems.
Why Some People Evade Colds And Others Don't People who have built up immunity to common viruses are less likely to get sick. But researchers say it's also possible some people are genetically less susceptible to catching a common cold.
Some people are simply more susceptible to getting sick than others. Lifestyle choices, environment, genetics, and age play key roles in determining immunity. Even if you cannot entirely control your immune system, fostering healthy habits might help protect you against infections.
According to the CDC, anyone who has a severe allergy (e.g., anaphylaxis) to any of the mRNA vaccine ingredients should not receive this vaccine. The CDC says people with allergies to certain foods, insects, latex and other common allergens can safely receive the COVID-19 vaccine.
By the 10th day after COVID symptoms begin, most people will no longer be contagious, as long as their symptoms have continued to improve and their fever has resolved. People who test positive for the virus but never develop symptoms over the following 10 days after testing are also probably no longer contagious.
A susceptible person is someone who is not vaccinated or otherwise immune, or a person with a weakened immune system who has a way for the germs to enter the body. For an infection to occur, germs must enter a susceptible person's body and invade tissues, multiply, and cause a reaction.
Your infectiousness is highest 1 day before the start of your symptoms and begins to wane about a week later for most people. The Omicron variant has a shorter incubation period, compared to other variants. For the Omicron variant, the incubation period is 1 to 4 days.
Coronavirus and respiratory syncytial virus (RSV) are two kinds of respiratory illnesses that have some similar symptoms. So far, the new coronavirus appears to be more dangerous for adults, especially older ones.
You may be considered immunocompromised if you:
A bone marrow transplant, also called a stem cell or Hematopoietic cell transplant, within the last 2 years, or longer than 2 years if you are taking medicines to suppress the immune system.
You can also spread COVID-19 in the 48 hours before your symptoms start. If you never have symptoms, consider yourself most infectious in the 5 days after you test positive.
Coronavirus questions answered
"There are going to be people who are less susceptible to viral infection because they have differences in their genes, such as genes that are important for viral entry into your cells." He said the notion of genetic resistance to infectious diseases was not without precedent.
You may need to get tested even if you do not have symptoms. You can have COVID-19 and spread it to others even if you do not have symptoms. Your COVID-19 test can be negative even if you are infected. Most people do not test positive for the virus until days after exposure.
If you are significantly immunosuppressed, you are more likely to be infectious for longer than 7 days and may still be able to spread the virus. Follow these measures until day 14 following your positive test result to further reduce any remaining risk of spreading the virus.
People with moderate or severe COVID-19 should isolate through at least day 10. Those with severe COVID-19 may remain infectious beyond 10 days and may need to extend isolation for up to 20 days.
Once you have had COVID-19, your immune system responds in several ways. This immune response can protect you against another infection for several months, but this protection decreases over time.
If you are allergic to polyethylene glycol (PEG), you should not get Pfizer-BioNTech or Moderna COVID-19 vaccine.
Protection against getting infected does appear to wane over time. Protection against death and severe disease also drops over time, but more slowly. You can increase your protection by getting a booster from 6 months after your primary course.
Pfizer: Is There a “Best” mRNA Vaccine? Both of the mRNA vaccines available in the US are highly effective against severe COVID-19, but recent studies suggest that Moderna's elicits a stronger immune response and might be better at preventing breakthrough infections.
