Dengue

Dengue is one of the commonest mosquito-borne viral diseases in human.It causes 50-100 million infections every year in tropical countries of Asia, South America and Africa. It is caused by dengue virus, which is transmitted by the daytime-biting of an infected Aedes aegypti mosquito. Dengue mosquito lives in cool, dark places and around homes, schools and other areas in towns and villages. The female mosquito lays her eggs in clean, stagnant, exposed collection of water like barrels, drums, pots, flower vases, plant saucers, tanks, discarded bottles/ tins, tyres etc. and a lot more places where rainwater collects. The first symptoms of the disease occur about 5-7 days after the infected bite. Symptoms of dengue include fever, headache, severe backache, flushing of the face. If anyone suspects dengue, he should consult with a physician. In a fraction of people bleeding from nose, gum, skin occurs, they can also develop shock. Those patients need hospitalisation for intensive care. To prevent dengue, people should be advised to use mosquito coils, sprays and other mosquito repeliants during the daytime. Babies, old people and others who may rest during the day should use mosquito nets. Curtains can also be treated with a suitable insecticide and hung at windows or doorways to kill or repel mosquitoes. Since mosquitoes which spread dengue breed in stagnant water, all water containers should be kept covered at all times. Discarded containers in which water collects e.g. bottles, cans, bags, tyres etc. should be destroyed. Water from air coolers, tanks, drums, buckets etc. should be drained out. Control measures should be taken by the city corporation along with NGO's & citizen to eliminate adult mosquitoes and eradicate their breeding sites.

Dengue Fever: A disease due to unhygienic environment 

Dengue fever has become the ‘talk of the country’ of Bangladesh at present. It has spread throughout whole Bangladesh in an epidemic form. It is a virus fever. There are four different antigenic varieties of dengue viruses and all are transmitted by the daytime biting of adies aegypty mosquito. They are DEN-1, 2, 3 & 4 serotypes. From these viruses, two forms of dengue are recognised. One of them is classical dengue fever and the other is dengue haemorrhagic fever. Classical dengue fever is characterised by the abrupt onset of fever, malaise, headache, facial flushing, troubles pain. This pain is worse on eye movements, conjunctival suffusion and some backache that is a prominent symptom. Lymphadenopathy, petichae on the soft palate and skin rashes may also occur. This classical dengue fever is recovered by seven days. The patient of classical dengue fever should drink adequate water, take complete rest, drink a lot of liquid food, wash whole body with wet-cloth and finally should take the tablets of paracitamol group to decrease the fever. Dengue haemorrhagic fever is very severe. It is believed to be the result of two or more sequential infections with different dengue serotypes. If the symptoms of dengue haemorrhagic fever of a patient are found, we should take him to the hospital and consult with a doctor immediately. We have to wash the patient’s body again and again with a wet-cloth to mitigate fever. At the extreme case, it may be bleeding. The patient may be given paracitamol but never should be given aspirin group. It is a disease of children and has been found in South Asia and Africa. Adies lays its eggs on standing or stagnant water in the holes of trees, plastic bottles, plastic cans, tin-pots, tyres, green coconut plates, polythene bags etc. All of us should be conscious about the eradication of adies mosquitoes and should take necessary steps for that. Besides, government should highlight it through different media and should take essential measures to protect dengue fever.

​  DENGUE FEVER

Dengue fever is a disease of Aedes mosquito-borne infection. Aedes mosquito bites during day and transmits dengue virus. It breeds in clean stagnant water both indoor and outdoor. If a person is infected, its symptoms become apparent in four to six days. Dengue virus originating from Africa, is now endemic in most tropical countries of Asia. According to the information of medical science at first dengue fever was experienced at Philadelphia in 1780. Death due to infection of dengue fever occurred in Australia in 1837. Dengue fever has broken out in Bangladesh in recent years. There are two types of dengue fever. They are classical dengue fever and Dengue Haemmorrhagic fever is fatal and it causes death with bleeding. There are four serotypes of dengue virus, such as DEN-1, DEN-2, DEN-3 and DEN-4. DEN-2 and DEN-3 are more serious. Dengue mosquito is about 5 millimetres in size with stripe on the body and legs and can fly up to about 50 metres at a time. It breeds in small pots, jars, drums and discarded plastic containers and tyres. It lives on blood and it Aedes female mosquitoes cannot breed without blood. There is no antidote of dengue virus. So we should take immediate action to prevent this disease.

Dengue Fever

Dengue fever is a mosquito-transmitted illness caused by the Aedes mosquito. Regions with tropical climates, such as the Indian Subcontinent, Southeast Asia, Southern China, Taiwan, the Pacific Islands, the Caribbean, Mexico, Africa, Central, and South America, are particularly susceptible to Dengue Fever outbreaks. The onset of symptoms typically occurs four to six days post-infection and can persist for up to ten days. Symptoms commonly include sudden onset of high fever, intense headache, eye pain, severe joint and muscle pain, exhaustion, nausea, vomiting, skin rash, and minor bleeding. In severe cases, symptoms may escalate to significant bleeding, shock, and even death. Individuals with compromised immune systems are at a higher risk of developing Dengue Hemorrhagic Fever, which can result in damage to lymph and blood vessels, internal bleeding leading to black vomit and feces, reduced platelet count, gastric sensitivity, and weak pulse. Regrettably, there is currently no specific treatment for Dengue infection, and medical professionals typically advise infected individuals to rest and maintain hydration. Hospitalization may be necessary if symptoms worsen. Prevention primarily involves avoiding mosquito bites as there is no widely available vaccine for the general population. Effective measures to reduce the risk of Dengue infection include maintaining clean living environments and neighborhoods to limit Aedes mosquito breeding sites. Remarkably, Aedes mosquitoes only require a small amount of water, such as a teaspoon, for egg-laying and larval development, emphasizing the importance of eliminating standing water in any form to prevent breeding. Therefore, the removal of stagnant water sources is imperative in mosquito control efforts.
