Which age group is most seriously affected by West Nile Virus?

The age group most seriously affected by West Nile Virus is older adults, particularly those over 50 years. This demographic is more vulnerable to severe manifestations of the virus due to factors such as a generally weaker immune response, the presence of underlying health conditions, and increased risk of complications.

Research shows that as people age, the likelihood of experiencing more severe illness rises significantly, with rates of West Nile neurological disease being particularly high in older populations. This vulnerability can lead to severe conditions, such as encephalitis or meningitis, which are serious complications associated with the virus. Therefore, it is important to highlight public health messaging targeting this age group to promote preventive measures, especially during peak mosquito activity seasons.

Other age groups, such as those younger than 20 or young adults between 21 to 35, do experience cases of West Nile Virus, but they typically demonstrate milder symptoms and have lower hospitalization rates compared to older adults.
