Which disease is included on the standard list of reportable diseases?

• A. Varicella
• B. Osteoporosis
• C. Acne
• D. Migraine

Answer: (A)

The key idea is that certain infectious diseases must be reported to public health authorities to monitor outbreaks and guide control efforts. Varicella is a contagious viral illness that public health agencies routinely track, so it commonly appears on the standard list of reportable diseases. Reporting varicella helps identify clusters, assess vaccination coverage, and trigger measures to prevent further spread. The other conditions—osteoporosis, acne, and migraine—are not contagious and are not typically required to be reported to public health for surveillance, so they don’t belong on that list. Remember that exact requirements can vary by jurisdiction, but the principle remains that reportable diseases are those that affect community health and require surveillance.
