       The CDC issued a health alert last month warning health care providers of an increased risk of dengue virus infection this year. Globally, new cases of dengue have been the highest on record, according to the CDC.

       Dengue viruses spread through mosquito bites. The most common symptom is a fever with aches and pains, nausea, vomiting and rash. Symptoms usually begin within two weeks after being bitten by an infected mosquito and last 2-7 days. Most people recover after about a week.

       The best way to prevent dengue is to avoid mosquito bites, according to the CDC.
