Defining Infectious Diseases: What Are They and How Do They Spread?
Infectious diseases are caused by pathogenic microorganisms such as bacteria, viruses, fungi, and parasites, which can spread from person to person through various routes of transmission. Common modes of transmission include:
Direct Contact: Transmission occurs through direct contact with an infected individual or their bodily fluids, such as saliva, blood, or respiratory droplets.
Indirect Contact: Transmission occurs through contact with contaminated objects or surfaces, known as fomites, which harbor infectious agents.
Airborne Transmission: Microorganisms can spread through the air via respiratory droplets or aerosols, particularly in crowded or poorly ventilated settings.
Vector-borne Transmission: Some infectious diseases are transmitted by vectors such as mosquitoes, ticks, or fleas, which serve as carriers for pathogens.
The Impact of Infectious Diseases on Public Health: From Outbreaks to Pandemics
Infectious diseases have a significant impact on public health, causing illness, disability, and death on a global scale. Outbreaks of infectious diseases can occur sporadically or in epidemic or pandemic proportions, posing serious challenges to healthcare systems and economies worldwide. Examples of infectious diseases that have shaped human history and continue to threaten public health include:
