 Cases of dengue fever in the Americas are reaching records this year. Puerto Rico declaring a public health emergency with the bulk of U.S. cases, over 1,700 reported. But this year, dengue infections are also being reported much farther north. The CDC reports nearly 200 people have been infected with dengue in New York and New Jersey. Mosquitoes spread the virus. Symptoms include aches, pains, nausea, vomiting, and rash lasting two to seven days. Most people recover in about a week. Dave Packer, ABC News, New York.
