Dengue: a mosquito-borne disease

Dengue is a mosquito-borne viral infection causing a severe flu-like illness and, sometimes causing a potentially lethal complication called severe dengue. Approximately, half of the world’s population is at risk and it affects infants, young children and adults. The incidence of dengue has increased 30-fold over the last 50 years. Up to 50-100 million infections are now estimated to occur annually in over 100 endemic countries, putting almost half of the world’s population at risk.

The Aedes aegypti mosquito is the main vector that transmits the virus that causes dengue. The virus is passed to humans through the bites of an infective female Aedes mosquito, which mainly acquires the virus while feeding on the blood of an infected person. The full life cycle of dengue fever virus involves the role of mosquitoes as a transmitter (or vector) and humans as the main victim and source of infection.

Once humans are infected, humans become the main carriers and multipliers of the virus; serve as a source of the virus for uninfected mosquitoes. The virus circulates in the blood of an infected person for 2 to 7 days, at approximately the same time that the person develops a fever. Patients who are already infected with the dengue virus can transmit the infection via Aedes mosquitoes after the first symptoms appear which normally occur within 4 to 5 days to maximum 12 days.

Bangladesh is one of the countries that are affected by dengue viruses. Almost every part of Bangladesh has now been affected by the deadly mosquito-borne disease. More than 13,600 patients have been diagnosed with Dengue in Bangladesh this Month.

Rohingya Refugee Camps in Cox’s Bazaar, Bangladesh:

Since beginning of July 2019, 15,369 dengue patients have been hospitalized. Of those 15,369 hospitalized patients 10,953 have been cured while the remaining 4,408 are still undergoing treatment. The government claims that only eight people have died of dengue this year but unofficial accounts say the number is much higher. Most of the dengue cases have been reported from Dhaka. On September, 2019 the World Health Organization (WHO) stated that the dengue situation is very alarming in Bangladesh but it was not YET out of control. In this situation, the Rohingya refugees are in a great trouble. To protect them from the mosquito borne disease, distribution of Long Lasting Insecticide Treated Net/mosquito net and mosquito hand Sprayers among the Rohingya refugees is an urgent and dire need of the present time.
