Which combination of diseases is commonly cited as notifiable in public health reporting systems?

• A. Malaria, Chickenpox, Hepatitis C
• B. Influenza, COVID-19, RSV
• C. Measles, TB, HIV
• D. Diabetes, Hypertension, Asthma

Answer: (C)

Notifiable diseases are those that must be reported to public health authorities so outbreaks can be detected quickly and appropriate actions can be taken. Measles, TB, and HIV are commonly cited because each represents a high-priority infectious disease with significant transmission risk or public health impact, and there are established reporting requirements in many jurisdictions. Measles is highly contagious and can spark outbreaks, TB requires ongoing surveillance and contact management to prevent spread, and HIV surveillance helps track epidemiology, allocate resources, and ensure linkage to care and prevention efforts. The other sets mix conditions that aren’t universally mandatory to report: chronic diseases like diabetes, hypertension, and asthma aren’t typically notifiable, and while influenza, COVID-19, RSV, malaria, or hepatitis C may be monitored or reported in various places, they aren’t as consistently labeled as notifiable across public health systems.
