What environmental condition may exacerbate impetigo?

1. High humidity

2. Cold temperatures

3. Windy weather

4. Low UV exposure

The correct answer is: High humidity

High humidity is a condition that can exacerbate impetigo. This skin infection, commonly caused by bacteria such as Staphylococcus aureus and Streptococcus pyogenes, thrives in warm, moist environments. High humidity can create the ideal conditions for bacteria to grow and spread, especially when combined with skin that may be injured or compromised. Moisture allows for the bacteria to live longer on the skin and makes it easier for them to infect open wounds or sores. This environment can lead to the rapid spread of impetigo, particularly in areas like schools or crowded places where children may come into contact with one another. In contrast, cold temperatures and windy weather do not provide the conducive environment for the growth of the bacteria that cause impetigo. Low UV exposure also does not directly correlate with exacerbating the condition as sun exposure can have some dermatological benefits, such as helping in the healing of certain skin issues, although it's important to balance exposure to avoid other skin issues. Thus, high humidity stands out as the primary environmental factor that can worsen impetigo cases.
