India achieves WHO'S "GET 2020" Goal of Infective Trachoma Eradication

India has now been declared free of Infective Trachoma, an infectious eye infection caused by Chlamydia trachomatis

India has achieved the WHO set "GET 2020" Goal for Infective trachoma infection eradication, announces the Union Health and Family Welfare Minister J.P. Nadda on Friday. The Infectious trachoma formerly well known to cause infectious blindness among children has now been eradicated in India.

Announcing it among the senior Health Ministry officials and faculty from Opthalmology Department of All India Institute of Medical Sciences (AIIMS), the minister said that the survey findings indicate that the active trachoma infection has been eliminated among children in all the survey districts with overall prevalence of only 0.7 per cent.

Nanosponges Can Help Treat Blinding Eye Infections
Using a mouse model, researchers demonstrate that engineered nanosponges can be used to protect eyes from infections caused by Enterococcus faecalis.

‘Infective trachoma mainly caused by Chlamydia trachomatis bacteria can cause roughening of inner eyelids, pain and eventual blindness due to the break down of outer surface or cornea of the eye ’

"This is much below the elimination criteria of infective trachoma as defined by the WHO. The survey findings indicate that the active trachoma infection has been eliminated among children in all the survey districts with overall prevalence of only 0.7 per cent," said Nadda, who also launched the National Trachoma Survey Report (2014-17).

Active trachoma is considered eliminated if the prevalence of active infection among children below 10 years is less than 5 per cent

According to medical sciences, trachoma is a chronic infective disease of the eye and is the leading cause of infective blindness globally.

37 Develop Eye Infection At Eye Camp Held In Madhya Pradesh
A total of 86 people had underwent surgeries at the eye camp organized in the month of November. But patients developed itching or liquid coming oozing out of the eyes due to infection.

Caused by poor environmental and personal hygiene and inadequate access to water and sanitation, it affects the conjunctiva under the eyelids and repeated infections cause scarring leading to in-turning of the eyelashes and eyelids.

This further causes damage to the cornea and subsequently blindness. It is found affecting the population in certain pockets of the states like Gujarat, Rajasthan, Punjab, Haryana, Uttar Pradesh as well as the Nicobar Islands.

In case of red eye, one should avoid over-the-counter eye drops as they may contain steroids which can be harmful, and instead seek medical advice.

The National Trachoma Prevalence Surveys and the Trachoma Rapid Assessment Surveys were conducted by Dr. Rajendra Prasad Centre for Ophthalmic Sciences, AIIMS, New Delhi in collaboration with National Program for Control of Blindness & Visual Impairment and Union Health Ministry from 2014 to 2017.

This was conducted in 27 high-risk districts across 23 states and union territories. Trachoma Prevalence Surveys were done in 10 districts selected from the previously hyper-endemic states.

Progress Made in Creating 'Good' Bacteria to Fight 'Bad' Bacteria in Eye Infections
Scientists are reporting progress in putting predator microbes to attack the dangerous bacteria that cause eye infections, which may lead to vision loss.

Under the survey, 19662 children in 1-9 year age group were examined by trained ophthalmologists. As many as 44,135 persons were examined among the 15yr+ age group. The Trachoma Rapid Assessment Surveys (TRA) was done in 17 other districts from other parts of the country in places where trachoma cases have been reported, which were not previously hyper-endemic.

Survey results indicate that active trachoma is no longer a public health problem in India.

"We have met the goal of trachoma elimination as specified by the WHO under its GET2020 program. This has been possible due to decades of inter-sectoral interventions and efforts that included provision of antibiotic eye drops, personal hygiene, availability of safe water, improved environmental sanitation, availability of surgical facilities for chronic trachoma, and a general improvement in the socio economic status in the country," said Nadda.

According to Praveen Vashist, head of the community opthalmology department at AIIMS, during the survey, more than 88,000 persons were examined.

He said that trachoma infection of the eyes was major reason behind blindness in India in 1950s and over 50 per cent population was affected in Gujarat, Rajasthan, Punjab, and Uttar Pradesh.
