A Vista resident was hospitalized with a rare local case of dengue fever, and County Vector Control responded with mosquito eradication efforts.

A Vista resident was hospitalized with a case of dengue, the second case of the mosquito-transmitted illness in San Diego County, health officials said today. The first case, which occurred earlier this month in Escondido, is not related to the second case, according to a statement from the San Diego County Health Department.

San Diego County health officials are investigating a second case of locally acquired dengue fever from this month. In a release Friday morning, a spokesperson for the county confirmed the case is not believed to be related to the other case of the disease acquired in Escondido earlier this month.

The first such local case of the mosquito-transmitted illness in San Diego County took place in Escondido earlier in October and is unrelated to the latest diagnosis
