Flu and Zika Update

March 6th, 2016

State health officials announce that since October, 19 Indiana residents have died of influenza-associated illnesses, including two children. According to the CDC, Indiana is experiencing widespread flu activity. H1N1 continues to dominate circulating strains.

Many of Indiana’s influenza-associated deaths this season have occurred among unvaccinated individuals, especially people who are at high risk of flu-related complications due to age or underlying medical conditions. The Indiana State Department of Health (ISDH) has also seen an increase in flu activity, including severe illnesses, in schools, long-term care facilities and correctional facilities in recent weeks.

The Centers for Disease Control and Prevention (CDC) reports that this year’s seasonal influenza vaccine is about 59 percent effective, which is among the highest rates documented by studies of the vaccine’s effectiveness. Flu season typically continues until May, and healthcare providers are encouraged to continue offering the vaccine to unvaccinated patients throughout the remainder of the season.

Thus far we have had 153 travel-associated Zika virus disease cases reported and zero locally acquired vector-borne cases reported.

Zika Transmission

Although spread is primarily by Aedes species mosquitoes, states have reported six confirmed and probable cases of sexual transmission of Zika virus from male travelers to female nontravelers. This suggests that sexual transmission of Zika virus might be more common than previously report.
