Question

recognizing methods of disease transmission
which situations put people at risk for disease transmission? check all that apply.
□ sneezing without covering their noses
□ disinfecting water from a local stream before drinking
□ cutting up vegetables on a dirty countertop
□ getting bitten from an infected mosquito
□ washing hands before handling food
□ having close physical contact with a person who is sick

Explanation:

• Sneezing without covering noses can spread respiratory droplets with pathogens, increasing transmission risk.
• Disinfecting water before drinking reduces risk, so this is not a risk situation.
• A dirty countertop may have pathogens that can contaminate vegetables, leading to disease transmission when consumed.
• Infected mosquitoes can transmit diseases (e.g., malaria, dengue) through their bites.
• Washing hands before handling food is a preventive measure, not a risk factor.
• Close physical contact with a sick person can transmit infectious agents (e.g., through droplets, direct contact).

Answer:

• sneezing without covering their noses
• cutting up vegetables on a dirty countertop
• getting bitten from an infected mosquito
• having close physical contact with a person who is sick
