A nurse noted that of 18 children in a day care center room, 5 became ill. Which of the following best describes a host factor that may be associated with this illness and who became ill?A. Some of the children were from very low socioeconomic families.B. Some of the children slept during rest time while others only rested.C. The bacterial cause of the illness was easily removed by hand washing.D. The day care center room was much warmer on three sides in comparison to the side with the floor to ceiling windows.
The correct answer is D
D. The day care center room was much warmer on three sides in comparison to the side with the floor to ceiling windows.
Explanation: Host factors refer to individual characteristics or factors that may increase a person’s susceptibility to getting sick. In this case, the room temperature can be considered as a host factor. Heat can create an ideal environment for bacteria and viruses to thrive and multiply. If the day care center room was warmer on three sides, it could lead to an imbalance in temperature and potentially create a conducive environment for the growth and transmission of pathogens. This could increase the likelihood of children becoming ill. Additionally, warmer temperatures can also weaken the immune system, making individuals more susceptible to infections. Therefore, the difference in room temperature could be a host factor associated with the illness in the children.
