What is a Virus Infection?

A virus infection stems, as the name implies, from viruses. Viruses are a type of tiny microorganism that feeds off of healthy cells in the body. This parasitic behavior means that they sometimes kill their host cells as they multiply.

Some common viral infections are:

  • Salmonella
  • Escherichia coli (E. coli)
  • Tuberculosis
  • Methicillin-resistant Staphylococcus aureus (MRSA)
  • Clostridium difficile (C. diff)
  • Bacterial pneumonia
  • Bacterial vaginosis
  • Vibrio vulnificus
  • Heliobacter pylori (H. pylori)
  • Bacterial meningitis

What is a Bacterial Infection?

Bacterial infections stem from bacteria, which are single-celled microorganisms. Bacteria may be within or on the human body, and while not all bacteria are harmful, “pathogenic bacteria” refer to the ones that can make a person sick.

Some common bacterial infections are:

  • Common cold
  • Flu
  • Encephalitis (inflammation of the brain)
  • Measles
  • Mumps

How Does It Spread?

Many bacterial and viral infections are contagious and can be spread by:

  • Coming into close contact with others with an infection
  • Coming in contact with infected body fluids
  • Getting bitten by an infected insect
  • Coming in contact with contaminated surfaces
  • Consuming contaminated food or water

How Do I Treat My Infection?

Viral Infection:

Viral infections generally can’t be cured directly, so the best course of action is to focus on alleviating symptoms while your body fights off the virus naturally.

Bacterial Infection:

Antibiotics fight bacterial infections by stopping bacteria from reproducing. Taking the full course as prescribed is essential to prevent the infection from lingering or becoming resistant to treatment.

Easy Ways to Feel Better at Home:

Support your recovery at home with these simple tips:

  • Drink plenty of fluids to maintain hydration.
  • Gargle with warm salt water to soothe your throat.
  • Take time to rest so your body can heal efficiently.
  • Ease nasal congestion with a humidifier or vaporizer.
  • Manage fever and aches with over-the-counter remedies.
