Second time dengue infection is more dangerous

According to official data, some 1,01,300 people were infected with dengue fever in Bangladesh in 2019. Dengue spread across the 64 districts that year. In 2022, a total of 62,321 people were infected with dengue. Of them, 281 patients died. This year, till June 10, some 3,021 people have been hospitalized with dengue. Among them 2, 276 people are in Dhaka while 745 outside of the capital city. So far, some 22 people died of dengue this year.

On the other hand, dengue kills an average of 1.5 people every hour across the world. Some 3 crore 90 lakh people are infected with dengue fever every year. Of the victims, 5,00,000 require hospitalization due to severe illness. Nearly 2.5 percent of the hospitalized patients died.

Dr Kabirul Bashar, Professor of Zoology Department of Jahangirnagar University (JU) and Entomologist, said, “Dengue is a viral fever transmitted by the Aedes mosquito. Dengue fever can be caused by any of the 4 distinct strains of this virus (DEN-1, 2, 3 and DEN-4). A person can contract dengue fever three times. Each re-infection of dengue fever can be much more dangerous than the previous infection.”

He said when a person recovers after being infected with a strain of dengue, his body develops an immune system against that type. So, the person doesn’t get infected a second time with the same strain. But, he/she can be infected a second time with any of the strains-2, 3, 4. The risk of re-infection and death from dengue fever is much higher than the first dengue.

This health expert believes that there is no specific treatment for dengue fever. According to him, there are ways to reduce the risk of contracting the virus by letting mosquitoes bite at any time of the day or night. Therefore, mosquito repellent must be used. If there is accumulated water, it should be thrown away regularly.

Dengue outbreak has spread in Bangladesh for long days. People concerned fear that due to the increase in dengue infection rate before the season comes this year, many people are likely to be infected with dengue for the second or third time.

Professor Dr Farhad Manzur said, “Pay more attention to the patient who got infected with dengue for the second time. Take the infected person to a doctor as soon as possible. The death risk from dengue will be greatly reduced if infected person is treated as per the doctor’s advice. Everyone be careful, be aware to avoid dengue.”

The Health Directorate has advised people to be vigilant and focus on cleanliness without being panicked over dengue. It said in a notification about the symptoms of dengue, if the body temperature is 104 degrees and some symptoms appear, doctor’s consultation should be taken if dengue is suspected. The symptoms are—severe headache, pain behind the eyes, pain in the muscles and joints of the body and frequent vomiting.

According to the Directorate General of Health Services (DGHS) about the symptoms of acute dengue, after 3 to 7 days of dengue, the body temperature may drop abnormally, severe abdominal pain, persistent vomiting, bleeding with vomiting, frequent breathing and feeling lethargic, restlessness.

The notification advises people to keep the windows of home or workplace closed at all times, and to cover the body as much as possible to avoid mosquito bites.

Awareness should be raised among families, neighbours and communities to prevent dengue and everyone should be directly involved in the cleanliness drive.

Abul Bashar Mohammed Khurshid Alam, Director General of Directorate General of Health Services, said that dengue infection is increasing at an alarming rate in the country at the beginning of the monsoon season. In this situation, even though the number of patients in the hospital is relatively low, all hospitals across the country have been prepared for dengue treatment.

Citing that more people are getting infected with dengue in the capital, he said, if someone is infected with dengue, he/she should consult a doctor immediately. Everyone should keep house, yard, workplace clean. Water from flower tubs, tin cans or AC must be thrown away within 2-3 days. It is possible to get rid of the menace of dengue only with the collective efforts and awareness of all.
