February 2008 Epidemiology Highlights

Influenza

Influenza is a viral respiratory illness that tends to strike in the Winter months. The risk for complications and hospitalizations from influenza are higher among persons 65 years of age and older, young children, and persons of any age with certain underlying medical conditions. Influenza has been very active in Utah this season. The most activity this season occurred during the month of February, when the number of people across the state ill with influenza-like symptoms surpassed outbreak levels. Roughly 75% of all influenza-associated hospitalizations for the season were reported in the month of February. Click here for more information.

Haemophilus influenzae (invasive disease)

The number of cases of invasive Haemophilus influenza (H. flu) reported to public health was higher than expected for year-to-date. However, due to recent changes in surveillance efforts, it is unclear whether this increase is significant. The reported cases of H. flu are of varying serogroup, and do not appear to represent a cluster or outbreak. Click here for more information on Haemophilus influenzae.

Hepatitis A

Four suspected hepatitis A cases were reported in Utah during February for a total of ten year-to-date. Hepatitis A is a liver disease caused by the hepatitis A virus. Hepatitis A can affect anyone. In the United States, hepatitis A can occur in situations ranging from isolated cases of disease to widespread epidemics. Good personal hygiene and proper sanitation can help prevent hepatitis A. Vaccines are also available for long-term prevention of hepatitis A virus infection in persons 12 months of age and older. Immune globulin is available for short-term prevention of hepatitis A virus infection in individuals of all ages. Click here for more information on Hepatitis A.
