High-yield overview: Dengue is an acute mosquito-borne viral disease transmitted mainly by the day-biting female Aedes aegypti. Since this mosquito breeds in clean water stored in and around homes, dengue prevention is chiefly based on weekly source reduction, community participation, surveillance, and rapid outbreak action. There is no routine antiviral treatment, so early recognition of warning signs, referral, appropriate fluid management, and avoidance of unnecessary NSAIDs/aspirin reduce deaths.
For PSM exams, concentrate on the epidemiological triad, Aedes indices, vector-control measures, surveillance, outbreak-control steps, and national programme.
Which section should I expand into detailed exam notes first?A complete PSM dengue note spans epidemiology, entomology, surveillance, prevention and outbreak response. I can build it section by section so it stays exam-oriented rather than becoming an unfocused long dump.Please choose one section for detailed PSM notes:
- Epidemiology and epidemiological triad
- Aedes mosquito: life cycle, breeding habits and indices
- Prevention and integrated vector control
- Surveillance, case definitions and outbreak investigation
- National programme in India
