A secondary infection is an infection that occurs during or after treatment of another, already existing infection. It may result from the treatment itself or from alterations in the immune system.
For example, a vaginal yeast infection that occurs after antibiotic treatment of a bacterial infection is a secondary infection. The development of bacterial pneumonia following a viral upper respiratory infection is another example.

yes, yeast infections.
Secondary strep infections invade tissue already weakened by injury or illness. They frequently affect the bones, ears, eyes, joints, or intestines.
Penicillin is effective against secondary infections of cancer. It is no cure for cancer.
To prevent secondary bacterial or viral infections, such as pneumonia.
These include protein deficiency, celiac disease, and some intestinal infections.
No, unless there are complications due to secondary bacterial infections due to torn skin from itching.
Yes, it causes a respiratory infection and can lead to deadly secondary respiratory infections.
Sometimes doctors will prescribe them to either prevent or treat a secondary infection. Some examples are lung or ear infections that may develop as a result of an initial viral infection.
They do not have an effect on swine flu, but can be helpful if a secondary bacterial infection occurs with the flu or after the flu. Antibiotics have no effect on viruses. The flu is caused by viruses. Antibiotics are for treating infections by bacteria, not for treating infections by viruses.
The immune system can have difficulty dealing with more than one type of germ at a time, so when it is busy fighting the flu, other microbes like bacteria can get a foothold. The problems a patient with the flu can have clearing phlegm from their lungs also allows opportunity for microbes (germs) to grow in the moist lung bases. Secondary pneumonia, either viral or bacterial, is the most common secondary infection in the flu.
Nosocomial infections are infections that are acquired in a health-care setting or as a result of receiving medical care. They may be the result of medical care (see iatrogenic infections, below), or they may simply be due to contact with pathogens from another patient in a hospital or clinic. Iatrogenic infections are infections that are the result of receiving medical care. Iatrogenic infections are nosocomial infections. Examples include infections as a result of surgery or catheterization, or secondary infections that are a result of antibiotic treatment killing of normal microbiota. Community-acquired infections are those that are picked up outside of a health-care setting. For example, CA-MRSA is the name given to MRSA infections that are transmitted in people's everyday lives.
Bee stings don't usually cause infections. There is no bee disease, viral or bacterial, that affects humans. Any infection at the sting site will almost certainly be a secondary infection caused by bacteria entering after the sting.
