The increased incidence of encephalitis in the summer months is due to
a. Maturation of the viruses.
b. Increased temperature.
c. The presence of adult mosquitoes.
d. An increased population of birds.
e. An increased population of horses.

검증된 단계별 안내

Understand that encephalitis is often caused by viruses transmitted by vectors, such as mosquitoes.

Recognize that the incidence of encephalitis increases in summer due to ecological and biological factors affecting the vector population.

Consider that adult mosquitoes, which are the primary vectors for many encephalitis-causing viruses, become more abundant in warmer months.

Evaluate the options: maturation of viruses and increased temperature alone do not directly explain the increased incidence; the presence of adult mosquitoes is a key factor because they transmit the virus to humans.

Conclude that the increased incidence of encephalitis in summer is mainly due to the increased population of adult mosquitoes, which facilitates virus transmission.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Vector-borne Transmission of Encephalitis

Encephalitis can be caused by viruses transmitted through vectors like mosquitoes. Understanding how mosquitoes act as carriers is crucial, as their population dynamics directly influence the incidence of encephalitis, especially during warmer months when mosquitoes are more active.

Seasonal Population Dynamics of Mosquitoes

Mosquito populations increase in summer due to favorable temperature and breeding conditions. Adult mosquitoes, which are capable of transmitting viruses, become more abundant, leading to a higher risk of vector-borne diseases like encephalitis during these months.

Role of Reservoir Hosts in Encephalitis Transmission

Birds often serve as reservoir hosts for encephalitis viruses, maintaining the virus in nature. While their population affects virus circulation, the direct cause of increased human cases is linked more to vector activity than to host population changes.
