Darville highlighted the possibility of bacterial infection in viral otitis media, and McCullers said human metapneumovirus, rhinovirus, respiratory syncytial virus and parainfluenza all can lead to secondary bacterial infections.

The symptoms of a bacterial infection and a virus are often very similar—fever, muscle aches, cough, and sore throat—but they require different treatments.

Interestingly, normal microbiota can be key players helping the body fight off infection. Resistance to and recovery from viral infections depends on the interactions that occur between the virus and its host. The host has a variety of defenses that it uses to prevent infection.

Treatment is the biggest difference between bacterial and viral pneumonia. Bacterial pneumonia is treated with antibiotic therapy, while viral pneumonia will usually get better on its own. In some cases, viral pneumonia can lead to a secondary bacterial pneumonia.

Viral infections that may be minor in normal, healthy individuals can be quite severe for people who have a weakened immune system. Almost any virus can lead to sepsis. Sometimes called blood poisoning, sepsis is the body's often deadly response to infection.

2﻿ Once you have gotten rid of such an infection, you're less likely to be reinfected with the same strain of the virus. Still, reinfection is possible. It's also possible to be infected with a different strain of HPV or hepatitis.

White blood cell count A mono infection typically causes your body to produce more white blood cells as it tries to defend itself. A high white blood cell count can't confirm an infection with EBV, but the result suggests that it's a strong possibility.

For example, a bacterial infection may be treated with antibiotics, while a viral infection often goes away on its own. If cancer is suspected, a biopsy may be done to confirm the diagnosis. Any swollen lymph nodes that don't go away or return to normal size within about a month should be checked by your doctor.

Bacterial gastroenteritis happens when bacteria causes an infection in your gut. This causes inflammation in your stomach and intestines. You may also experience symptoms like vomiting, severe abdominal cramps, and diarrhea. While viruses cause many gastrointestinal infections, bacterial infections are also common.

So once your body overpowers the virus, usually by the fourth day, then the fever goes down. If it doesn't go down, then, yes, it's a good idea to make sure your child doesn't have some bacterial like an infection, a urinary tract infection, or something else that would require antibiotics to treat.

What's the difference between a viral and bacterial throat infection? A viral infection is the most common cause of a sore throat according to the NHS. If your sore throat is caused by a virus, antibiotics are unlikely to help.

Viruses are smaller than bacteria and can't survive without a living host. A virus attaches itself to cells and usually reprograms them to reproduce itself. Also, unlike bacteria, most viruses do cause disease. Some virus-caused diseases include the common cold, AIDS, herpes, and chickenpox.

If your acute or chronic sinus infection is caused by a virus or fungi, it is possible to spread these pathogens to another person. Symptoms can potentially look like a common cold, which can later develop into a reoccurring sinus infection. Infection of the sinus caused by bacteria is not contagious.

Knowing the difference can save you time and money during cold and flu season. The symptoms of a bacterial infection and a virus are often very similar—fever, muscle aches, cough, and sore throat—but they require different treatments.

Mono flare-up EBV, which usually is what causes a mono infection, remains in your body for the rest of your life. It's usually in a dormant state, but the virus can be reactivated.

Illnesses like influenza, or “the flu,” and upper respiratory infections (URIs) fall under the category of viral infections, while illnesses such as pneumonia, sinusitis and ear infections are considered bacterial infections.

As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.
