op het nieuws heb ik gezien over het zika virus, een virus dat zo dadelijk in hele usa zal groeien. dus de andere kant van de wereld blijkt een besmettingsgevaar voor ons of de hele wereld, zullen wij dan ook er aan geraken. maar waar komt die mug of vlieg vandaan ?
en in de andere landen wil ik het ook nader onderzoeken

Spread of disease and prevention
[edit][/size]
Aedes aegypti is a
vector for transmitting several tropical fevers. Only the female bites for blood, which she needs to mature her eggs. To find a host, these mosquitoes are attracted to chemical compounds emitted by mammals. These compounds include
ammonia,
carbon dioxide,
lactic acid, and
octenol. Scientists at the
Agricultural Research Service have studied the specific chemical structure of octenol to better understand why this chemical attracts the mosquito to its host.
%5B4%5D They found the mosquito has a preference for "right-handed" (
dextrorotatory) octenol molecules.
The yellow fever mosquito can also contribute to the spread of
reticulum cell
sarcoma among
Syrian hamsters.

The
CDC traveler's page on preventing dengue fever suggests using
mosquito repellents that contain
DEET (N, N-diethylmetatoluamide, 20% to 30% concentration, but not more). It also suggests:
- Although Aedes aegypti mosquitoes most commonly bite at dusk and dawn, indoors, in shady areas, or when the weather is cloudy, "they can bite and spread infection all year long and at any time of day."%5B6%5D%5B7%5D
- The mosquitoes prefer to breed in areas of stagnant water, such as flower vases, uncovered barrels, buckets, and discarded tires, but the most dangerous areas are wet shower floors and toilet tanks, as they allow the mosquitos to breed in the residence. Research has shown that certain chemicals emanating from bacteria in water containers stimulate the female mosquitoes to lay their eggs. They are particularly motivated to lay eggs in water containers that have the correct amounts of specific fatty acids associated with bacteria involved in the degradation of leaves and other organic matter in water. The chemicals associated with the microbial stew are far more stimulating to discerning female mosquitoes than plain or filtered water in which the bacteria once lived.%5B8%5D
- Wear long-sleeved clothing and long trousers when outdoors during the day and evening
- Spray permethrin or DEET repellents on clothing, as mosquitos may bite through thin clothing
- Use mosquito netting over the bed if the bedroom is not air conditioned or screened, and for additional protection, treat the mosquito netting with the insecticide permethrin
- Spray permethrin or a similar insecticide in the bedroom before retiring
Mosquito control is currently the best method for disease prevention. This primarily includes source reduction, pesticide spraying or "fogging", or the use of mosquito traps
