What is the mode of transmission for pertussis?

• A. Airborne
• B. Droplet
• C. Vector-borne
• D. Contact

Answer: (B)

The mode of transmission for pertussis, commonly known as whooping cough, is primarily through droplet transmission. When an infected person coughs or sneezes, respiratory droplets containing the bacteria can be expelled into the air. These droplets can then be inhaled by individuals nearby, leading to the spread of the infection.

This mode of transmission emphasizes the importance of good respiratory hygiene practices, such as covering the mouth and nose while coughing, as well as ensuring that those who are infected stay away from others, especially vulnerable populations like infants and those with compromised immune systems. Vaccination is also a critical control measure in preventing the spread, highlighting the need for public health initiatives to educate and promote immunization against pertussis.
