CDC expands bug repellent roster to fight West Nile

first_img While they still affirm the safety of DEET, officials acknowledged that some people just don’t like the product. Alternatives have existed—picaridin was approved by the Environmental Protection Agency (EPA) for US use years ago, a CDC official said—but there was little commercial interest. With the advent of WNV, mosquito repellents are getting more attention. In two recent studies, oil of lemon eucalyptus provided about the same protection as low concentrations of DEET against mosquitoes found in the United States, according to the CDC. The substance, also known as PMD, is available in several products in the United States. The product has not been tested against mosquitoes that spread malaria and some other diseases that occur internationally, the agency says. CDC WNV pageshttp://www.cdc.gov/ncidod/dvbid/westnile/index.htm “These additional repellents will help prepare people to prevent mosquito bites this summer,” Petersen said. Apr 28 CDC news releasehttp://www.cdc.gov/media/pressrel/r050428.htm CDC’s “Updated information regarding insect repellents”http://www.cdc.gov/ncidod/dvbid/westnile/RepellentUpdates.htm Most people who contract WNV experience no symptoms, but about 20 percent can have symptoms such as fever, headache, nausea, and vomiting. About 1 in 150 people can suffer a severe illness, which may involve high fever, stupor, coma, tremors, convulsions, vision loss, and paralysis, the CDC said. In 2004, 2,470 Americans fell ill with WNV and 88 of them died. However, milder cases are believed to be underreported, Petersen said. Centers for Disease Control and Prevention (CDC) officials held a teleconference to announce they have endorsed the repellents picaridin and oil of lemon eucalyptus as effective tools for fending off mosquitoes that can carry WNV and other pathogens. “There are a great many people who are unprotected against mosquito bites,” she said. “West Nile Virus can be a terrible disease. It’s worthwhile to take those few seconds to reduce your risk of becoming infected.” Dec 29, 2004, CIDRAP News report on WNV activity in 2004http://www.cidrap.umn.edu/cidrap/content/other/wnv/news/dec2904wnv.html Zielinski-Gutierrez said only about 40% of people reported using mosquito repellent when surveyed late last year. Use in the Pacific Northwest and among Latinos is particularly low, she added. Both picaridin and the plant-based oil of lemon eucalyptus are EPA-approved for use as directed, said Dr. Emily Zielinski-Gutierrez, a behavioral scientist with the CDC’s VID division. Picaridin, also known as KBR 3023, will be sold as “Cutter Advanced.” The substance provides protection that is “often comparable with DEET products of similar concentration,” a CDC news release says. See also: Both chemicals have been used successfully in other countries, said Dr. Lyle Petersen, director of CDC’s division of Vectorborne Infectious Diseases (VID). They are comparable to varying levels of DEET, the chief repellent that has been used in the United States. And both have been approved by the Environmental Protection Agency. A CDC fact sheet on insect repellents says DEET and picaridin have shown a higher level of efficacy in peer-reviewed studies than other repellents the EPA has approved for safety and efficacy. CDC’s new advice reflects a concern that more people need to take precautions against WNV, a mosquito-borne disease that has spread to 47 of the 48 contiguous states since first appearing on US soil in New York City in 1999. Washington state is the holdout, but Petersen said he wouldn’t be surprised to see WNV appear there this year. April 28, 2005 (CIDRAP News) – Just in time for mosquito season, federal health officials today heralded the addition of new defensive weapons against West Nile Virus (WNV): two non-DEET mosquito repellents. Today’s recommendation marks a policy shift for CDC, which has long recommended DEET-containing products to repel mosquitoes. In fact, the CDC’s WNV page still contained a graphic of DEET this afternoon with the words, “Remember to use repellent with DEET when spending time outdoors.” Petersen said localized outbreaks of WNV are hard to predict and may depend on weather and other factors. That’s one reason personal vigilance is the key to good protection. The CDC recommends that people use insect repellent anytime they go outside during mosquito season, especially at night, when mosquitoes are most active.last_img read more

Lucas: SAS partnership getting better

first_img However, Lucas believes that is only the beginning of something special. “The link between Luis and Daniel is only getting better,” he said. “Last year they didn’t have a chance to play many games (Sturridge arrived in January but injuries and suspension had an impact on their partnership) so this season we can see they are scoring goals. “When you have two strikers in the good form they are we always have to make sure we defend well because we will create chances and score goals.” Suarez claimed all the headlines with his treble, which began with an individual run and nutmeg on Jonas Olsson and was followed by a powerful 17-yard header before nodding in a Steven Gerrard free-kick, but Lucas felt Sturridge’s strike surpassed them all. “I think Daniel scored the best goal to be honest,” added the Brazil midfielder. “Luis’s header was a great header and the first goal was typical Luis – the ‘meg’ and the good finish but I think overall it was four fantastic goals. “It’s just great to see them linking well and we hope this will continue during the season.” Press Association Liverpool were coasting at 3-0 before James Morrison’s 66th-minute penalty gave the visitors hope and they enjoyed a good 10-minute spell before Sturridge finished them off in style. “We are disappointed we conceded a goal – I’ve seen it again and I don’t think it was a penalty,” said Lucas. “But I think we got back and Daniel killed the game very well. For 75 minutes we were very consistent, pressing and playing good football. “I think it was a great performance overall, especially when you play at home and get an early goal.” While the forwards rightly received most of the praise manager Brendan Rodgers felt Lucas also deserved some credit. The 26-year-old missed last week’s draw at Newcastle after the birth of his second child, daughter Valentina, but slotted straight back in. His role as defensive linchpin often goes unrewarded but Rodgers knows having the Brazilian in a holding role gives his more creative players much more freedom. “When you play that system you are looking for someone to have that controlling role because that allows the two advanced (midfield) players to go forward more,” said the Reds boss. “Lucas came in and filled that really well. I thought he was excellent – as was Jordan Henderson and Steven Gerrard. “They were always available for the ball, it was very good. “It was the best 90 minutes of the season. I thought we looked a very good team. “The confidence was good, how we pressed the ball was good and the front two are as good as it gets and the support behind that is very good – and we have players like (Philippe) Coutinho to come back next weekend.” Liverpool midfielder Lucas Leiva believes the partnership of Luis Suarez and Daniel Sturridge is improving with each match – and points to the quality of the goals they score as proof. Suarez grabbed his first Anfield hat-trick, and his fourth in total for the club, in the 4-1 win over West Brom although there was an argument for Sturridge netting the best effort with a delightful delicate chip to put the result beyond doubt. The pair already have 14 league goals between them this season – and Suarez was suspended for the first five games of the campaign. last_img read more
