For the second week in a row, the state saw fewer reports of confirmed influenza cases, according to a Department of Health Services report released Thursday.
Across Arizona, there were 820 confirmed influenza cases during the week ending March 5. To date, there have been more than 8,200 confirmed cases for the 2010-11 season, which began in September. Two weeks ago, there were about 1,300 cases, the highest weekly total this season.
Influenza is a respiratory illness often marked by fever, coughing and congestion. The number of influenza cases may be much higher since few people go to the doctor or are tested, health officials say.
