Dengue fever:
The rate of spread of dengue in Delhi is rampant, with the total number of cases reported in just the first week of November being 1,171. The number of dengue cases reported in the national capital in the month of October was 1,196.
- The spike in dengue, malaria and chikungunya cases across Delhi is leading the local bodies and authorities to increase their fogging and spraying drives.
- The citizens are also being directed to make sure that there is no stagnant water collected near or inside their houses, as it provides a breeding space for the disease.
- Dengue virus is transmitted through the bite of a female Aedes (Ae.) mosquito.
- Aedes is a day time feeder and can fly up to a limited distance of 400 meters.
- Although it usually results in mild illness, severe dengue infections can sometimes prove fatal.
- World Health Organization (WHO) estimates suggest an annual incidence of 100-400 million dengue infections every year, with its global incidence growing dramatically “in recent decades”.
- Incidence of dengue has grown dramatically around the world in recent decades, with a vast majority of cases under-reported, according to the World Health Organization (WHO).
- WHO estimates 39 crore dengue virus infections per year, of which 9.6 crore show symptoms.
- India registered over 1 lakh dengue cases in 2018 and over 1.5 lakh cases in 2019, according to the National Vector-Borne Disease Control Programme (NVBDCP).
