A local lawmaker is urging residents to protect themselves from the flu.  Danbury State Senator Mike McLachlan is urging residents who have not been vaccinated to get a flu shot.  This comes in response to a report from the state Department of Public Health about a high number of influenza cases, particularly in Fairfield County.  While the flu may not be serious for most people, for the elderly, young children, and those with compromised immune systems, the flu can be deadly.  McLachlan says Connecticut has already reported four flu-related deaths this winter.
