Dengue after covid-19

Monsoon rains have ebbed while air pollution has risen to over 500 AQI in Gurugram area while in the national capital it also touched over 472 and also signals the start of outbreak of fatal pathogens such as Dengue and Chikungunya. Dengue is caused by a virus of the Flaviviridae family and there are four distinct, but closely related, serotypes of the virus that cause dengue (DENV-1, DENV-2, DENV-3 and DENV-4). Recovery from infection is believed to provide lifelong immunity against that serotype. The rise of Dengue cases has rang alarm bells which, as per a recent report, reached nearly 300 cases reported in the national capital in the first four days of November 2022. This figure took the infection tally of the vector-borne disease to more than 2,400 so far this year. The dengue infection tally had stood at 2,175 till October 26, and 295 cases have been recorded this month till November 4. Meanwhile, nearer to Nagaland, there were over 270 cases of dengue detected in Assam’s Karbi Anglong district within the last five days, since November 1. According to official sources in Assam, preventive measures have been initiated against the ‘impending epidemic.’ All government and private schools and colleges falling under the Diphu Municipal Board and Greater Diphu Town area have been ordered to remain closed from November 7 to 12 according to the order issued by principal secretary, Karbi Anglong Autonomous Council. There are already around a dozen confirmed cases of Dengue in Dimapur area alone. Health authorities are gearing up for any likely major outbreak unless there is a consistent and determined effort to rid sources of mosquito breeding. Health and civic authorities, particularly in the foothill areas, should have already started a vigorous campaign to get rid of stagnant water in and around houses or utilise fogging equipments to spray on larger areas. Dengue is transmitted by the bite of an infected female Aedes Aegypti mosquito. The mosquito becomes infected when it feeds on the blood of a person infected with the virus. After about one week, the mosquito can then transmit the virus while biting a healthy person. The symptoms of Dengue include: flu-like symptoms that can last for two to seven days. Dengue fever usually occurs after an incubation period of 4-10 days after the bite of the infected mosquito. High Fever (40°C/ 104°F) is usually accompanied by at least two of the following symptoms: headaches, pain behind eyes, nausea, vomiting, swollen glands, joint, bone or muscle pains and rash. There is no vaccine or specific medication for dengue fever. Patients are advised rest and to drink plenty of fluids. Paracetamol can be taken to bring down fever and reduce joint pains. A person suffering from a severe form of dengue fever may need to be treated in an intensive care unit (ICU). Treatment may include blood and platelet transfusion, Intravenous fluids and oxygen therapy.Doctors have cautioned patients against taking aspirin or ibuprofen should as these could increase the risk of bleeding. Vector-borne diseases are not unexpected since this has been a cyclic occurrence. The severity is also dependent on the counter measures undertaken such as ensuring clean environment and spraying places where mosquitoes gather or breed. The other is preparedness by the medical department in meeting any situation arising out of likely outbreak.
