Consultant Paediatrician Dr LakKumar Fernando, who was the Founder-Head of the Centre for Clinical Management of Dengue & Dengue Haemorrhagic Fever (CCMDDHF) in Negombo gives a quick guide for both people and doctors managing dengue:
- If you get a fever, check the temperature with a thermometer. Do not touch the forehead and assume there is fever or not. Keep a record of the temperature.
- If possible, do a Dengue NS1 Antigen Test between 20 and 30 hours after the onset of the fever. Do not delay by 2-3 days, for the antigen test needs to be done towards the end of the first 24 hours of fever to catch more than 95% of cases. When doing the antigen test, ensure the laboratory is credible and that it uses authentic test kits.
- With the same injection prick, do a Full Blood Count (FBC) as the next most important test.
- If it is affordable, do a CRP (C-reactive Protein) test too, which would come normal, if the patient has only dengue and no other infection.
- The first day’s FBC is useful, as if dengue comes out positive, you need to repeat the FBC the next day.
- In general, patients should get admitted to hospital when the platelet counts are dropping – nearing 100,000 or dropping below 100,000. (Usually, the platelet count should be over 150,000.)
- However, if the second FBC shows a rapid platelet drop (e.g., from 400,000 on the first day to 200,000 on the second day), admission of the patient to hospital would be a safe option.
