Dengue Fever: Aedes aegypti mosquito

The number of dengue cases is rising at an alarming rate in the Capital, with civic agencies reporting nearly 30 cases each day. The mosquito-borne viral infection has already crossed the 500 mark in the Capital, with 520 cases being reported till Wednesday.

To tide over the outbreak-like situation, the civic agencies have strengthened their dengue surveillance and are taking strict action against those found neglecting residential or commercial properties and allowing mosquitoes to breed.

On Wednesday, the agencies released a cumulative data. Nearly 300 people were challaned in areas across the city, which included schools, Metro stations, government buildings and houses.

“We are on our toes and are doing everything we can to ensure there is no outbreak,” said Dr PK Sharma, director, medical officer (health), New Delhi Municipal Council.

According to the experts, this year Dengue-II strain is prevalent, which is known to be more virulent of the four strains.

“Our healthcare workers are alert and whenever there is a need, they are fogging areas where adult mosquito breeding has been found,” said Sharma.

With fogging as a method of controlling mosquito-breeding having come under scanner, the civic agencies claim they prefer taking anti-larval measures and use fogging only as a last resort.

Causes and Prevention

  • Dengue is transmitted through the bite of female Aedes aegypti mosquito. The mosquito passes on Flavi virus from an infected individual to a healthy individual.
  • The Dengue mosquito can be easily identified by the naked eye by its characteristic black & white striped legs and body.
  • Your chance of contacting Dengue is higher especially 2 hours after sunrise and 2 hours before sunset, as the Dengue mosquito is most active during this period.
  • Mosquito repellants containing DEET and Picaridin are highly effective against Dengue mosquitoes.
  • Create hygienic environment indoors and outdoors by ensuring water does not get collected anywhere as these are the ideal breeding places for the Dengue mosquito.
  • Dengue infection peaks during the monsoon. It is important to take control measures to eliminate the mosquitoes and their breeding places during this time.
  • People living in metros and cities are more vulnerable to contacting Dengue fever because Dengue fever mosquito lays eggs in stagnant clean water.
  • Mosquito nets treated with permethrin have higher effectiveness in controlling the Dengue fever mosquito because it is an effective mosquito repellent.
  • Spray Pyrethroid-based, commercially safe aerosols in rooms including closets, bathrooms and kitchens to eliminate mosquitoes. Keep the rooms closed for 15-20 min for best results.
  • Introduce larvivorous fishes, e.g., Gambusia / Guppy, in ponds & fountains as these small fishes eat mosquito larvae.                                                                                   

Symptoms, Complications and Advise

  •  The first symptom of Dengue is bi-phasic fever, that is, high fever that drops to normal and then suddenly rises back to high fever.
  • Severe headache, pain behind the eyes, muscle and joint pains, and decrease in urine output are the most prominent symptoms of Dengue fever.
  • Undiagnosed Dengue fever can result in Dengue hemorrhagic fever, which is a life threatening complication usually occurring in 3–7 days after the first symptom.
  • Red blisters under the skin, blood in vomit, black stools, bleeding from mouth, nose and gums, severe abdominal pain, fatigue & restlessness are all symptoms of Dengue hemorrhagic fever.
  • In Dengue fever, if the blood platelet count drops to 80,000 and below, chances of uncontrolled bleeding increases. A normal person’s average count ranges from 150,000 to 450,000.
  • Platelet is an important blood component responsible for clotting in case of injury. The blood platelet count falls down significantly in Dengue fever increasing risk of uncontrolled bleeding.
  • Patients of Dengue fever should keep close watch on any injury as even a minor cut can cause uncontrolled bleeding because of fall in platelet count.
  • Patients of Dengue fever should brush their teeth gently as vigorous brushing can result in bleeding gums.
