For most people on earth, when mosquitoes we mention mosquito, what crosses the mind, is the popular malaria infection. It is so popular that some people attribute common fever as malaria. Another infection whose vector is also the mosquito, the DENGUE fever, a viral infection, and though not as prevalent, can kill, and it is very much amongst us, affecting both young and old.
Should we be concerned?
With more than 100 countries in the Americas, Africa, western Pacific, Eastern Mediterranean, and Southeast Asia now designated as endemic, which contrasts to 9 severe dengue epidemic countries in 1970, the battle against the virus is far from over. With the back and forth case prevalence of dengue fever, it will require a concerted public health effort and strong political will to halt the virus.
What is and what are the symptoms of dengue fever?
Dengue fever, a flu-like illness can be severe with a temperature of about 40c/ 104F, dengue should be suspected when the symptoms of severe headache, swollen glands, nausea, muscle joint pains, and pains behind the eyes follow. Transmitted by the mosquito Aedes aegypti, dengue fever has four types, namely: DEN-1, DEN-2, DEN-3, and DEN-4.
What causes dengue fever?
Now that you know what is Denise Fever, what causes it? The mosquito Aedes aegypti is fingered as a primary vector of dengue. The female mosquito, the usual culprits, transmits the virus to healthy individuals after biting infected humans, who serve as The Host. Infected humans, whether they show symptoms or not, carry and multiply the virus and, in the process, serve as a source of infection to uninfected mosquitoes.
For those in danger of dengue fever
To understand those in danger of this fever, I will need to classify into three epidemiological groups of (1) person (2) place (3) time.
It affects infants, young children, and adults. Because it rarely causes death, most people recover after being infected for the first time and develop immunity to the dengue type. However, resistance to one of the four dengue types does not confer immunity to the rest. The risk of developing dengue hemorrhagic fever, a severe and deadly dengue fever, increases when one is infected from second to multiple times.
Aedes aegypti loves to breed in human-made containers and, as a result, thrives in semi-urban areas. Countries in Southeast Asia, the Americas, and western Pacific regions are the worst hit. Outbreaks have been recorded in Africa and Europe.
Aedes aegypti does not follow the feeding pattern of most mosquitoes. It prefers to feed in the day time. Early in the morning and before dusk is its preferred biting time. Those who Farm or stay Outdoors during those times are at risk.
Treatment and control approach
Currently, the virus does not have the treatment, and though a certain vaccine exists, it does not seem to be a useful tool. The best approach to preventing dengue fever remains vector control, and the following approaches are key:
1) Removing mosquito habitats
2) Putting on protective clothing
3) Use of insecticides
4) Screening housing
