Dengue Fever – Brazil
March 24, 2022 – Four dengue-related deaths have been reported in Araraquara, Brazil this year. The individuals were the following: a male adult aged 73 years, a female adult aged 68 years, a female adult aged 39 years, and an adult male aged 77 years. All deaths occurred on different days in the month of March of 2022. To-date, there have been approximately 1,400 cases reported.
According to the source, a majority of the breeding environments of the mosquitoes carrying the virus were found within homes. The rising outbreak has prompted the operation of Dengue Care Centers. Those who show symptoms related to the disease are encouraged to seek prompt screening and care.

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.
