Lymphatic filariasis in India

Lymphatic filariasis in India refers to the presence of the disease
To treat, prevent, and eliminate the disease, the Indian government provides mass drug administration (MDA) to achieve mass deworming. The treatment is a few pills taken once a year for five years. The medication provided is diethylcarbamazine.[citation needed] For the treatment to work 60-80% of people in large regions must take this yearly treatment for several years.
Treatment
Treatment is done through a public health initiative in which most people in regions with the parasite take treatment. The treatment is a mass drug administration to cause mass deworming. In India the worm only lives in humans, so if everyone takes treatment, and everyone is cured, then the worm will be permanently eradicated. India participates in the global eradication program to eliminate the worm worldwide.[citation needed]
Health education for the public is an essential part of the campaign.[2] Hundreds of millions of people in affected communities have to agree to take the drugs once a year.[2] In a 2015 public health campaign called Hathipaon Mukt Bharat shows how the disease causes large feet, says the medicine is safe, and tells people to take it.[2]
The treatment program varies in different places in India. Various reports describe the variation, such as for Assam[7] and Andhra Pradesh.[8]
Most people who take treatment have no negative effects or only mild
Vector
99% of infections in India happen when the mosquito
The typical prevention for filariasis is through the use of medication.[12] However, in some areas, using the pesticide spinosad to eliminate mosquitoes is helpful to prevent the spread.[12]
To eliminate the disease neither humans nor mosquitoes should have the parasite.[13] The usual way to determine whether filariasis is eliminated from an area is to test humans for the parasite.[13] In some special cases India uses molecular xenomonitoring to examine captured mosquitoes and determine if they carry the parasite.[13]
Epidemiology
By 2006 there were 20 million people infected and with symptoms, 30 million people infected but asymptomatic, and 470 million people who were at potential risk.[1] In 2005 95% of the cases in India were in Andhra Pradesh, Bihar, Gujarat, Kerala, Maharashtra, Orissa, Tamil Nadu, Uttar Pradesh and West Bengal.[14]
India has 40% of the world's lymphatic filariasis (LF) cases.[15] For patients, one of the major costs of treating the disease is that of being unable to work for some time.[15] A year 2000 survey reported that about half the people in India were at risk of contracting LF.[16] Men and women are equally susceptible to this disease, but in the past, there have been barriers to women accessing treatment.[17] An estimate from the year 2000 reported that filariasis in India caused an annual economic loss of ₹5000 crore (US$1,000,000,000).[15]
Society and culture
The
In 1955 the Indian government established the National Filaria Control Programme (NFCP) as a project to limit the spread of the disease.[19][1] By 1959 that organization proposed various plans for controlling or eliminating the disease.[20] Infections spread out of control from 1955 until 1995 in which time the number of cases increased several fold.[1] Reasons for the disease's expansion included increased urban population and a rapidly changing country which exposed people to new circumstances with mosquitoes.[21]
In 1997 India joined a World Health Assembly resolution to eliminate LF by 2020.[19] In India to achieve this goal healthcare must be very accessible to almost everyone at risk for the disease.[22] The Indian government originally planned to eliminate the disease by 2015, then shifted the date to 2017, then to 2020.[23] Various media outlets have discussed how India might meet the goal or what it should happen next if more time is required.[24][25][26]
In 2015 the Indian government launched a health campaign called Hathipaon Mukt Bharat (Filaria Free India) to encourage public participation in eliminating LF.[27][28] In the program everyone in an area with the disease takes pill medicine once a year for five years.[23] The drug is diethylcarbamazine citrate and albendazole and is in the form of about four pills which people take all at once.[23]
Research
Public health researchers have applied machine learning techniques to improve public health monitoring for filariasis in India.[29]
A 2019 report identified dogs in Kerala who have another worm which can cause filariasis, Brugia malayi.[30] This worm is not known to infect people in India.[30] If necessary tests are ready to identify the dogs carrying the disease.[30]
