Seroprevalence of toxoplasmosis in Kumaon region of India.

To determine the seroprevalence of toxoplasmosis, 200 random serum samples were collected from the villages of Kumaon region of Uttar Pradesh (India). These samples were tested for antitoxoplasma antibodies using indirect haemagglutination (IHA) test. Sera of 800 patients clinically suspected to have toxoplasmosis who attended a major hospital in New Delhi were also screened for these antibodies. The results showed that toxoplasma infection in Kumaon population is quite high (57%); the seroprevalence in women being as high as 77 per cent--the highest reported so far in India. The results indicate the need for urgent epidemiological measures.
