Pradip Chatterjee  | MP  |  19 Oct 2022 | Kolkata: Serotyping conducted by the health department suggests that Deng III and Deng II subtypes are still predominant in the state. Out of the total dengue infected patients, around 52 per cent of them have been found to be affected with Deng III subtype of dengue in October while around 40 per cent patients have been infected with Deng II subtype. 

Deng II subtype carried out much damage in 2019. Deng II is more deadly and causes more deaths and severity as well. The Deng III subtype is much less harmful. As around 40 per cent of patients are affected with Deng II, the transmission rate is much higher this year. 

Serotyping tests are being carried out at School of Tropical Medicine and also at NICED from time to time. Entomological surveys carried out by the state health department reveals that discarded household containers within the domestic and peri-domestic areas are found to be a major threat of dengue in various parts of Bengal. 

It has also been found that water-storing practice due to its scarcity in hilly regions of north Bengal is also a major factor for transmission in the area. Awareness campaigns are being carried out. In a survey report published by the state health department, it has been stated that under the Kolkata Municipal Corporation (KMC) area, the borough 14 has seen the highest rise in dengue cases from 39th to 40th week.
