What is a Virus Infection?

A viral infection is caused by microscopic organisms called viruses. They survive and multiply by invading healthy cells, which they often damage or destroy in the process.

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?

Bacteria are single-celled microorganisms that can be found almost anywhere, including the human body. The harmful ones, known as pathogenic bacteria, are responsible for causing infections.

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

Your Guide to Infection Treatment

Viral Infections:

Unfortunately, most viral infections don’t have a direct cure. Instead, treatments aim to manage symptoms while the virus resolves on its own.

Bacterial Infections:

Bacterial infections are treated with antibiotics, which work by preventing bacteria from growing. Completing your full prescription is crucial to avoid antibiotic resistance and ensure the infection is fully cleared.

Home Treatments to Ease Symptoms:

Whether you’re dealing with a bacterial or viral infection, some at-home remedies can ease your symptoms:

  • Stay hydrated by drinking plenty of fluids.
  • Gargle with warm salt water for throat relief.
  • Prioritize rest to help your body heal.
  • Use a humidifier to reduce congestion.
  • Take over-the-counter medicines for pain or fever.
