Bharathy, I have listed a few of the more recent articles below that reference the situation in India or provide some good information/references.  I would also encourage you to write the article in English for a wider audience in India as well as in Tamil.  Also, be careful if you find references in the Predatory Publications as they may have misinformation.

Thanks Robert john wolff.

Reza Nassiri sir pls send your mail ID 

Dr, my student Dr.Divyamol Thomas worked on serodiagnosis of Toxocara larva migrans in uveitis patients in collaboration with Sankara Nethralaya, Chennai and I found the following information on her literature review.

In India a positive antibody response to TES antigen was reported in 6.4 per cent subjects residing in a rural area near Chandigarh and in 23.3 per cent of patients clinically suspected to have toxocariasis by Malla et al. (2002). Shobana (2003) reported a 14.84 per cent strong positive and 27.34 per cent strong positive reaction against TES by ELISA during screening of sera samples from pet practitioners, animal handlers and final year students of Madras Veterinary College, Chennai.

Dar et al. (2008a) conducted a study on prevalence of anti Toxocara antibodies among children of Anantnag and Pulawama district of Kashmir valley and reported a total seroprevalence of 32.72 per cent where the result showed a significant difference in seroprevalence between male and female children of Anantnag district but no significant difference observed between the age groups.

Dar et al. (2008b) reported a seroprevalence of 32.86 per cent in children of six districts of Kashmir valley and found that gender was a significant factor for Toxocara infection in children with a 41.97 per cent incidence in males while compared with 20.94 per cent in females.

I think that it may be useful for you.

thank you all I got good source of information I will start writing now
