COMMUNICABLE DISEASES (MALARIA, DENGUE, SWINE FLUE)

Communicable diseases are infections caused by pathogens such as bacteria, viruses, fungi, or parasites that spread from one person to another through direct contact, airborne droplets, bodily fluids, or contaminated surfaces. Examples include influenza, tuberculosis, COVID-19, measles, and hepatitis.

These diseases can also be transmitted through vectors like mosquitoes (e.g., malaria, dengue). Prevention strategies include vaccination, proper hygiene, safe food handling, and using protective measures like masks and handwashing. Early diagnosis and treatment with antibiotics, antivirals, or other medications help control their spread. Public health measures play a crucial role in managing outbreaks and reducing transmission within communities.
