For a Fun and Safe Tropical Getaway, Plan Ahead

Posted 17 Feb 2017 by Drugs.com

FRIDAY, Feb. 17, 2017 – If you're planning a tropical getaway, be sure to pack old standbys like bug spray and sunscreen – and maybe a lot more, a doctor advises. "In places like the Caribbean and South and Central America, where it is already summertime, people can potentially be exposed to health risks that they may not have at home," said infectious disease specialist Dr. Christopher Ohl. He is head of the International Travel Clinic at Wake Forest Baptist Medical Center in Winston-Salem, N.C. In the Caribbean and Central America, you can get sunburned in as little as 10 minutes. Wear sunscreen and a T-shirt or cover-up during the middle of the day when the sun is strongest, Ohl advised in a center news release. Be especially careful on the beach or at poolside where the water reflects sunlight. Also, be careful about what you eat and drink to reduce the risk of diarrhea. Safest ... Read more

Scientists Create Mosquitoes Resistant to Dengue Virus

Posted 12 Jan 2017 by Drugs.com

THURSDAY, Jan. 12, 2017 – Scientists say they have created mosquitoes resistant to the dengue virus, which might eventually help control the spread of the disease in humans. The team at Johns Hopkins Bloomberg School of Public Health in Baltimore genetically modified Aedes aegypti mosquitoes to boost their natural ability to fight infection by the virus. Mosquitoes get infected when they feed on someone who has the disease. Then they pass dengue to healthy people by biting them. Each year, dengue sickens about 96 million people worldwide. The virus kills more than 20,000 people, mostly children, the researchers said. "If you can replace a natural population of dengue-transmitting mosquitoes with genetically modified ones that are resistant to virus, you can stop disease transmission. This is a first step toward that goal," said study leader George Dimopoulos, a professor of molecular ... Read more

Why Major Zika Outbreak Is Unlikely in U.S.

Posted 3 Jan 2017 by Drugs.com

TUESDAY, Jan. 3, 2017 – The United States' comfortable standard of living makes a large-scale outbreak of Zika virus unlikely, a new scientific paper suggests. Exposure to mosquitoes in the United States is limited by widespread access to clean water, air conditioning, screened doors and windows, and other household amenities that most Americans take for granted, said lead author Max Moreno-Madrinan. He's an assistant professor with Indiana University-Purdue University Fairbanks School of Public Health in Indianapolis. Thus, the mosquito-borne Zika virus is not likely to gain a foothold in the United States as it did in Brazil and a host of other Latin American countries, according to Moreno-Madrinan. More than 80,000 people in 69 countries have been infected during an ongoing Zika outbreak that originated in Brazil in 2015. The prevalence of mosquito-transmitted diseases like Zika in ...

Mosquitoes Can Deliver Zika/Chikungunya Double Whammy

Posted 15 Nov 2016 by Drugs.com

MONDAY, Nov. 14, 2016 – Mosquitoes can infect people with Zika and chikungunya viruses at the same time, new research suggests. And another study found that in addition to Zika virus, two other mosquito-borne viruses – chikungunya and dengue – can also cause severe neurological problems. In the first study, Colorado State University researchers discovered that Aedes aegypti mosquitoes can carry Zika and chikungunya viruses at the same time, and can secrete high enough levels of both viruses in their saliva to potentially infect people with both in a single bite. It's the first time this has been confirmed, the researchers said. In the second study, researchers in northeastern Brazil identified severe neurological problems in patients treated during a rare and unprecedented simultaneous outbreak of Zika, chikungunya and dengue in 2015. It was already known that Zika can cause ... Read more
