Infectious diseases are a diverse group of illnesses caused by pathogenic microorganisms, such as bacteria, viruses, fungi, and parasites. These microorganisms can spread from one person to another through various routes, including:
- Direct contact: This can occur through skin-to-skin contact, sexual contact, or contact with respiratory secretions (e.g., coughing, sneezing).
- Indirect contact: This can occur through contact with contaminated surfaces or objects, or by ingesting contaminated food or water.
- Vectors: This can occur through the bites of insects or other animals that carry the infectious agent.
Common examples of infectious diseases include:
