According to doctors, the more common DEN 1 strain manifests in symptoms such as fever and body ache. But the second strain leads to high-grade fever, vomiting, rashes in the chest and dengue shock syndrome.
Dr Ajay Kumar Gupta, director of internal medicine at Max Super Speciality Hospital in Vaishali, said the DEN 2 strain could also lead to multi-organ failure. Although Noida has not reported any dengue death so far, two patients have died in neighbouring Ghaziabad. But it is not clear if the patients had the DEN 2 strain because Ghaziabad is yet to send any sample for a sero survey.
“This time, most of the dengue patients have been complaining about high fever, body ache and nausea. In 5-10% of such patients, the symptoms are prolonged. If immediate medical attention is not given in such cases, it could lead to organ failure. Just remember, a drop in platelet count does not necessarily determine the severity of the infection. A proper examination is required,” Dr Gupta said.
Noida malaria officer Shruti Kirti Verma agreed. “Unlike DEN 1, the DEN 2 strain is more severe. Such symptoms should be reported to a doctor immediately.”
With the rising number of cases, ICU and emergency beds have been ramped up at the District Hospital. Sero sampling, Verma said, will also be conducted at Child PGI.
Officials said 50 beds were reserved for dengue patients at the District Hospital and another 240 were being readied for a spurt in cases.
With 30 new cases, dengue numbers reached 353 in Noida on Tuesday. Ghaziabad added 10 cases, taking the total to 432. The patients in Ghaziabad are across a varied age group – the youngest one is a 6-year-old-girl from Sanjay Nagar and the eldest a 73-year-old woman from Vasundhara.
Officials said malaria teams were scanning areas to check for the presence of mosquito larvae. If found, anti-larvae solution is being sprayed in such areas and in the vicinity of houses of dengue patients.
