Is it possible to catch the influenza twice?
Yes, because the virus can mutate (change). If you become infected with the swine flu virus, your body produces antibodies against it, which will recognize and fight off the virus if the body ever meets it again.
Can you get the same strain of flu twice in a season?
Generally, the answer is: no, you can’t. But the bad news is that there are so many viruses and germs flying around (particularly during the winter months), you’ve got a high chance of catching another one instead.
Are you immune to the flu after having it?
Flu viruses continually change over time. This constant changing enables the virus to evade the immune system, so that people are susceptible to the flu throughout life.
Can flu come back after a few days?
If your symptoms go away and then come back a few days later, you may have a secondary infection. See a doctor if you suspect a secondary infection. If left untreated, pneumonia can be life threatening.
Why does my flu keep coming back?
If your symptoms persist more than 10 days or keep coming back, then something else may be going on, such as allergies, sinusitis, or a secondary infection.
Why do I keep getting the flu over and over?
It is possible to get sick regularly when the immune system is not functioning correctly. The reason for this is that the body is unable to fight off germs, such as bacteria, properly. If an infection occurs, it can take longer than usual to recover.
What’s the difference between flu A and flu B?
Unlike type A flu viruses, type B flu is found only in humans. Type B flu may cause a less severe reaction than type A flu virus, but occasionally, type B flu can still be extremely harmful. Influenza type B viruses are not classified by subtype and do not cause pandemics.
Can you pass the flu back and forth?
Fortunately for you and others dealing with multiple infections in the same household, the answer to all of your questions is no. Since you and your family members are almost certainly infected with the same strain of the virus, you won’t pass it around again.
Can you get sick 2 times in a row?
Yes, you can catch the same cold twice, depending on the strength of your immune response. Most of what we know about immunity to cold viruses is based on studies performed in the late 1950s and early ’60s.
Does getting the flu make your immune system stronger?
Getting the flu itself can provide much stronger immunity than any flu shot does.
Does the flu weaken your immune system?
His results demonstrated that the influenza virus triggers a bodily response that causes a rise in serum glucocorticoid levels, leading to systemic immunosuppression. Such effects render the body vulnerable to bacterial infections that would otherwise be innocuous.
