Entitled to be endemic for dengue, Delhi has been witnessing a tremendous increase in dengue outbreaks for a couple of decades.

The cited case reflects the incident of a 50-years old AIIMS worker. The patient was detected to be infected by dengue virus; however, did not have a fever.

Key facts about dengue:

  • Dengue is as a viral infection mediated by mosquitoes.
  • Infection is characterized by a flu-like illness. Occasionally, the infections progress toward a lethal stage called severe dengue.
  • Global incidence shows an exponential phase of growth in the number of dengue patients.

Dengue symptoms and precautions:

Dengue symptoms and precautions

Characterized by a sudden onset, symptoms of dengue are inclusive of fever (lasting for 3-7 days), intense headache, pain in muscles and joints, appetite loss, vomiting and diarrhoea. In severe cases, patients may exhibit rashes on the skin with nose or gum bleeding.

Prolonged fatigue and depression often accompany recovery period.

Precaution from Dengue:

  • In case, a person is suffering from symptoms of dengue fever, it is advisable to remain indoors to stay protected from mosquito bites.
  • No availability of dengue vaccine.
  • Personal hygiene and environmental protection from mosquitoes are essential to prevent yourself from falling prey to dengue infection.
  • Appropriate solid waste disposals.
  • Vector monitoring and surveillance is must to identify the adequate levels of control interventions.

AIIMS case study:

The dengue patient revealed no evidence for fever. Experiencing frequent fatigue, doctors asked the patient to go for a routine blood test. The report revealed raised acid levels in the blood accompanying uncontrolled levels of sugar. A decreased count for red blood cells, white cells, and platelets called for a dire dengue test.

Affirming the NS1 antigen test result, the patient was further subjected for RT-PCR. Reverse Transcription Polymerase Chain Reaction (RT-PCR) re-assured the onset of dengue infection.

What does the study infer?

 According to the AIIMS doctors, dengue testing must be considered as one of the differential diagnosis in endemic areas. This especially applies to those patients where there are no symptoms of fever. Still, the patient suffers from leucopenia and thrombocytopenia. Leucopenia is characterized by declined white blood cell count; while thrombocytopenia is described by dropped platelet count.

Majorly old, diabetic and immune-compromised individuals are at the risk of dengue infection without a characteristic fever.

Thus, people residing in dengue-endemic areas should be aware of dengue symptoms and precautions to emancipate themselves from its wrath.
