Question 11

Transmission modes of infectious disease include airborne & droplet.

Airborne and droplet are recognized modes of transmission for infectious diseases, indicating that pathogens can spread through the air via tiny particles or larger respiratory droplets.

A) airborne & isolation

While airborne transmission is indeed a valid mode, isolation is not a mode of transmission but rather a control measure used to prevent disease spread. Therefore, this option is incorrect as it conflates a mode of transmission with a preventive strategy.

B) droplet & disinfection

Droplet transmission is a correct mode; however, disinfection is a preventive measure aimed at reducing infection risk rather than a mode of transmission. Thus, this option incorrectly pairs a transmission method with a control measure.

C) contact & isolation

Contact transmission is a legitimate mode of disease spread, but isolation, similar to the previous options, is a control measure rather than a transmission mode. Hence, this option is also incorrect for the same reason.

D) airborne & droplet

This option correctly identifies two distinct modes of transmission for infectious diseases. Airborne transmission involves pathogens that remain suspended in the air over distances, while droplet transmission involves larger respiratory droplets expelled during coughing, sneezing, or talking. This makes it the correct choice.

Conclusion

The correct answer, airborne and droplet, accurately describes recognized transmission modes for infectious diseases. Other options mistakenly combine transmission methods with control measures or incorrectly identify modes, leading to their inaccuracy. Understanding these transmission modes is crucial for effective disease prevention and control strategies.
