High-tech mosquitoes could combat Zika virus

(URBAN NEWS SERVICE) Genetically modified mosquitoes could mean curtains for the Zika virus. New U.S. cases of Zika virus infections are continually being discovered, as the Food and Drug Administration looks to these high-tech mosquitos as a possible solution.
Zika’s potential to spring from mosquito “nurseries” in the American South could hammer poor minority communities as summer heats up. Atlanta has the nation’s worst mosquito problem, according to Orkin, the pest control company. Mosquitoes only need standing water to spawn.
Scientists believe Zika spreads when a female mosquito feeds off of an infected person and later bites a new victim. Harmless male mosquitoes feed on flower nectar. Zika also can be transmitted through sexual intercourse with an infected partner. Symptoms, while rare, can last for a week and range from a mild fever to muscle and joint pain.
Concerns rocketed after last year’s discovery that Brazilian babies with unusually small skulls and brains were born to mothers who contracted the virus while pregnant. Brazil’s Zika woes continue as athletes, fans, journalists and others from around the globe prepare to converge on Rio de Janeiro for the 2016 Summer Olympics.
Fulton County, which includes Atlanta, is battling potential local Zika infections. The Aedes aegypti, which lives in the Deep South, is one of several mosquitoes that scientists believe spread the virus.
Specialists with Fulton County’s Department of Health and Wellness, according to the agency, are working with Georgia’s Department of Public Health and the Atlanta-based U.S. Centers for Disease Control and Prevention to monitor outbreaks and educate the community.
“The mosquitoes that spread Zika virus will bite four or five people before they are satisfied,” said Nancy Nydam, spokeswoman for Georgia’s health department.
She said people should use insect repellent, eliminate standing water around their homes and stay indoors during dawn and dusk, when mosquitos are most active.
An $85-million fund is available to states, cities and territories at risk of Zika outbreaks, the CDC announced on May 13, 2016. The money would finance Zika-prevention efforts only temporarily, said Dr. Stephen C. Redd, a director at the agency. More money from Congress is needed, he said.
The CDC reported that between January 1, 2015 and May 18, 2016, all of the 544 U.S. Zika cases are travel-associated, meaning the virus was originally contracted abroad. To date, 157 pregnant women in the U.S. have reported symptoms.
New York logged 114 travel-related cases, the highest number in America. Florida was second with 109, and California’s 44 cases put it in third. Texas was fourth, with 35 reported infections. These states all have high black and Hispanic populations, foreshadowing what this disease could do to these communities.
Among 836 Zika cases in U.S. territories, 832 were contracted locally. These include 803 infected people in Puerto Rico, 15 in the Virgin Islands, and 14 in American Samoa.
Oxitec, a British biotechnology company, is testing its genetically modified male Aedes aegypti mosquitoes in Key Haven, Florida. Oxitec’s male mosquitoes mate with wild female Aedes aegypti, producing offspring that “have a very high probability of dying before they reach adulthood,” according to its website.
