What infection control measures are standard for suspected respiratory infections in a public health setting?

• A. Only wearing gloves and no isolation.
• B. Vaccination of all staff regardless.
• C. Isolation of the ill person, droplet precautions, appropriate PPE, hand hygiene, and vaccination of contacts as indicated.
• D. No PPE, no isolation, and no hand hygiene.

Answer: (C)

Infection control for suspected respiratory infections in a public health setting relies on a layered approach to prevent transmission. The standard practice is to isolate the person who is ill, apply droplet precautions, use the appropriate PPE, maintain strict hand hygiene, and vaccinate contacts as indicated to reduce onward spread.

Why this is the best approach: Isolation removes the source of infection from others, while droplet precautions and suitable PPE limit exposure to respiratory droplets that can carry pathogens. Hand hygiene stops transmission via contaminated hands, and vaccinating contacts as indicated lowers the chance that exposed individuals become infected and pass it on.

Other options don’t provide comprehensive protection: wearing gloves alone without isolation doesn’t stop the main transmission route; vaccinating all staff regardless of exposure isn’t targeted or necessarily needed for immediate control; and having no PPE, isolation, or hand hygiene would allow rapid spread.
