Dengue Fever – India
October 16, 2021 – Approximately 243 new cases of dengue have been reported in Delhi, India. This brings the total count to 723 cases to-date. One death has been recorded. The deceased individual was an adult female aged 35 years from the Sarita Vihar in south Delhi. She was initially admitted to a hospital for immediate treatment and shortly died after.
According to the source, the mosquitoes that harbor the dengue virus breed in clear waters between the months of July and November, sometimes up to December. As this is the month of October, it is likely that the population of mosquitoes carrying the dengue virus is high in this region and individuals have been exposed to them.
General symptoms of dengue include fever. Officials state that there are current efforts in place to control the mosquito population during this time. One of the examples include a week long campaign that was implemented for vector control initiatives.

Dengue fever is a mosquito-borne disease caused by the dengue virus. Dengue is spread by several species of female mosquitoes but typically by a mosquito that has white markings on its legs and sides.
Dengue can exist anywhere that mosquitoes live and is fast becoming a global problem. As the world’s climate becomes warmer, the mosquito’s distribution has increased significantly in the past decades. Dengue is fast becoming a larger problem than malaria.
Symptoms may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash. In a small proportion of cases, the disease develops into severe dengue, also known as dengue hemorrhagic fever. A later reinfection can also cause serious complications.
Controlling mosquito populations is the main way to prevent and reduce dengue. Wearing long-sleeved clothing and long trousers when outdoors is always a good idea. In countries where the disease is endemic, use mosquito netting over the bed if the bedroom is not air conditioned or screened.
The first record of a case of probable dengue fever is in a Chinese medical encyclopedia from the Jin Dynasty (265–420 AD) which referred to a "water poison" associated with flying insects. The primary mosquito vector, A. aegypti, spread out of Africa in the 15th to 19th centuries due in part to increased globalization secondary to the slave trade.
The origins of the Spanish word dengue are unknown, but it is possibly derived from "dinga" in Swahili, meaning a disease caused by an evil spirit.
