Many individuals are often unaware that dengue mosquitoes may bite at night. Although the odds of getting bitten by dengue and chikungunya-carrying mosquitos are higher during the day, they can also bite a person at night and infect them.
Mosquitoes spread disease through their saliva which includes drugs to kill bacteria, viruses, and parasites. They inject this poison into you when you get a mosquito bite. Some diseases transmitted by mosquitoes include dengue, yellow fever, malaria, and filariasis. Dengue is spread by four types of mosquito: Aedes aegypti, Aedes albopictus, Ae. Quadrannulatus, and Culex pipiens. Nighttime bites from any of these mosquitoes can lead to a dengue infection.
People usually think of mosquitoes as being nocturnal, but they will bite during the day too. If you are out in the sun during the daytime, use sunscreen with an SPF of at least 15. This will help prevent you from being bitten. You should also try to avoid areas with high insect populations such as vacant lots, garbage bins, and pig farms.
The dengue-carrying mosquito is a day-biting mosquito that is most active two hours after sunrise and several hours before sunset, although it also bites at night in well-lit places. Dengue virus can live for several days outside of its host, so it is possible to get infected by a mosquito that has bitten an infected person during the previous day or night.
Dengue fever is not dangerous but it can be serious if you are already sick with another disease. There is no treatment for dengue other than time. Get medical help if you have any symptoms such as high fever, severe headache, nausea, vomiting, diarrhea, muscle pain, or rash. In some cases, patients need to receive blood transfusions or intravenous fluids.
It is important to know that there are three types of dengue viruses: DV1, DV2, and DV3. Only type 2 viruses have been found in the Americas. So if you have dengue symptoms and they do not seem to be related to infection with DV1 or DV3 viruses, then you should be tested for type 2 viruses using laboratory tests. There is no vaccine available for any type of dengue virus yet.
Experts say that if the light rain and associated drop in temperature seen overnight persist, the Aedes mosquito responsible for dengue and chikungunya might die naturally. "A little rain wouldn't hurt. A daytime temperature of 16 degrees Celsius is required. If it gets any lower, the mosquitoes will die," explains Dr Richard Besser, director of the Centers for Disease Control and Prevention's division of vector-borne diseases.
But a continuous fall in temperature could lead to more outbreaks of these diseases. "Our results show that without intervention, there would be another outbreak of disease around this time of year. If it rains and the temperature drops enough, more mosquitoes would survive and another outbreak is likely to occur," says study co-author Andrey Rodionov.
The study also showed that if control measures such as draining pools of water where the mosquitoes breed or using insecticides are used, there would be fewer cases of dengue and chikungunya. "These findings have important implications for the future management of these diseases," concludes Rodionov.
Dengue fever develops after being infected with one of four different types of dengue virus.
Mosquito bites really itch more at night, and you're not seeing things. "Most individuals itch more at night because our cortisol levels (our bodies' natural anti-inflammatory chemicals) are greater in the morning, and we are also less distracted as we wind down and try to go asleep," explains Dr. Kassouf. That means when you get bit by a mosquito, it's actually making your skin tougher so that another bite doesn't cause as much pain.
If you're waking up in the middle of the night with itchy arms, there is a good chance you were bitten by a mosquito. Mosquitoes feed during daylight hours but they need your blood to reproduce. So even though they don't feel like it, they're actually trying to hurt you by scratching that itchy mark on your skin.
There are two types of mosquitoes: Old World and New World. Old World mosquitoes include such species as Aegypti, Anopheles, Culex, and Maalox. These mosquitoes live in tropical climates around the world and they like it warm enough for them to breed, which is why most countries in the tropics have problems with these pests. New World mosquitoes include Aedes, Argiope, Coquillettidia, and Uranotaenia. They live in temperate climates and they can survive outside of water for some time; this is how they spread diseases such as dengue and yellow fever.
The only way to tell the difference between a dengue mosquito bite and a regular mosquito bite is that a dengue mosquito bite is more redder and itchier. Otherwise, they look exactly the same.
Dengue fever is not dangerous to adults, but it can be serious for children because their immune systems are still developing. There are four different types of viruses that can cause dengue fever and research has shown that some people may develop a severe form of the disease if they are infected with more than one type of virus.
The symptoms of dengue fever include headache, pain behind the eyes, feeling tired, and a rash. The symptoms usually appear 6-14 days after being bitten by a mosquito and can last for several days. Some people may also have fluid leaking from their nose, mouth, or ears. This is usually clear fluid but it could be pink or yellow in color depending on the person.
People who are diagnosed with dengue fever should take care of themselves while they are sick. That means drinking plenty of fluids, staying indoors as much as possible, and taking medications as prescribed by your doctor. Not taking proper care of yourself could lead to complications such as bleeding inside the body or even death.
