Communicable diseases, also known as infectious or transmissible diseases, are illnesses caused by microorganisms such as bacteria, viruses, fungi, and parasites. These diseases spread from person to person through various modes of transmission, including direct contact, airborne droplets, contaminated surfaces, and vectors like mosquitoes. Examples include influenza, tuberculosis, HIV/AIDS, malaria, and COVID-19. Globally, communicable diseases are a leading cause of morbidity and mortality, disproportionately affecting low- and middle-income countries. They impose significant economic and social burdens, often straining healthcare systems, disrupting economies, and perpetuating poverty. Outbreaks such as the COVID-19 pandemic highlight the need for robust global health security measures and coordinated international responses. Prevention and control strategies play a critical role in mitigating the spread of these diseases. Vaccination, hygiene practices, safe food and water, vector control, early diagnosis, and appropriate treatment are essential measures. Public health education and disease surveillance are equally crucial in fostering awareness and enabling early intervention. Technological advancements, such as mRNA vaccines and artificial intelligence, have enhanced our ability to respond effectively to emerging and re-emerging diseases.
