Dengue erupts in various parts of Bangladesh. Hospitals are overcrowded with the patients and deaths are also reported. It is the worst Dengue outbreak in Bangladesh history. Health experts believe that the Dengue outbreak in Bangladesh is due to the heavy rains of the monsoon season. These heavy rains provided a perfect environment for the mosquito-borne virus.
Dengue fever is not a new thing for the residents of Bangladesh. However, the recent Dengue outbreak in Bangladesh is unprecedented. Directorate of General Health Services(DGHS) states that hundreds of patients are being admitted to hospitals every day. DGHS says that more than 2000 patients have been admitted on Wednesday. According to DGHS data more than 30,000 people are infected by Dengue.
There are disputed figures on deaths due to dengue outbreak in the country. Media reports claim that more than 80 people have died due to dengue, while DGHS claims that twenty-three deaths are reported. Medical experts believe that knowing the cause of death is difficult. It needs the collection of blood samples of all the affected patients. Medical experts believe that most of the deaths are caused by dengue shock syndrome. It is a severe complication caused by secondary infection.
Sri Lanka, The Philippines, and Honduras are also facing the dengue crisis. Medical experts believe that the early symptoms of Dengue include headache, muscle and joint pain, nausea and fever. Swollen glands and rashes are also included in dengue symptoms. Its severe symptoms appear after 3 to 7 days of infection. Severe symptoms include bleeding gums, abdominal pain, and rapid breathing.
The World Health Organization (WHO) says that the dengue is caused by a virus with three different strands. Recovery from one strand gives lifetime immunity from that specific strand. However chances of the recovered patients to become the victim of other strands increase. When patients suffer from dengue for 2nd or 3rd time the pattern of symptoms also changes. They suffer shock syndrome or severe dengue.
In previous years Bangladesh faced DEN-1 and DEN-2 strand, but this year DEN-3 and DEN-4 are more common. The DEN-3 and DEN-4 are considered as more dangerous and can cause plasma leakage and organ impairments in patients.
Aedes Mosquito is a carrier of dengue virus. It breeds in clear water and grows in a subtropical climate. It also prefers to live in urban and suburban areas. Bangladesh’s capital Dhaka offers Aedes a suitable environment to grow. The city has thousands of building sites. These sites became pools of stagnant water during the monsoon season.
Although the dengue cases are being reported from all over the country, about 80 percent of cases are from the capital Dhaka.
Urban Planning experts opine that cities like Dhaka are being developed in an unplanned manner. And this lack of planning provides breeding sites for mosquitoes. Dhaka’s city corporations are also not working under urban planning.
According to a report Dhaka South City Corporation (DSCC) and Dhaka North City Corporations (DNCC) have used an expired or ineffective spray. Which resulted in increased breeding of mosquitoes.
Medical experts believe that fogging the streets is nothing more than an eyewash. Dhaka authorities claim that they are working after having consultations with neighboring India.
About seven years ago, Kolkata faced a dengue outbreak. But City’s administration took decisive steps to stop the menace.
No doubt the dengue outbreak in Bangladesh is becoming dangerous. However, raising awareness can resolve this issue. People should be given awareness on how to destroy the breeding sites for mosquitoes. Effective cooperation between different authorities of the City can minimize the likelihood of dengue for next year.
