Influenza can be serious 流感可不簡單
To many people, influenza may just be a minor ailment. Caused by the influenza virus, infected individuals may require hospitalization if the condition is severe. Elderly people are particularly susceptible to severe influenza because of weakened immunity. The map shows the distribution of influenza cases admitted to a district hospital between March and November 2010 in Hong Kong. The dots and circles represent the resident location of influenza patients requiring hospitalization. People at or above the age of 65 people accounted for a majority of the influenza patients, many of which were residents of elderly homes (house symbols). It is not uncommon to find multiple patients (circles) in the same elderly home, which may be a result of cross infection. Yearly vaccination is an important means of protecting old people from severe influenza diseases. Data used in this map were obtained from a study conducted at the Alice Ho Miu Ling Nethersole Hospital in Tai Po District in the North East of Hong Kong.
