Thus the people who are at most risk for swine flu include children younger than five years of age, elderly people over 65 years of age, pregnant women, adults or children who suffers from various medical conditions like asthma, metabolic disorders like diabetes, pulmonary problems, hematological, neurologic and neuromuscular and immunosuppression. Children and adolescents who are less than 18 years of age and have been receiving long term therapy for aspirin may also be at risk for having the Reye syndrome after the virus infection. Moreover residents of chronic care facilities and nursing home also have high risk of getting infected with swine flu as they are surrounded by people having the infection.
