Police in Utter Pradesh are looking for a fake doctor who they say, is infecting patients with HIV.
Nearly 40 cases have been identified in three villages.
Medical superintendent Pramod Kumar Dohre says the man has been using the same tainted needle for injections to treat scores of patients.
(SOUNDBITE) (Hindi) MEDICAL SUPERINTENDENT, PRIMARY HEALTH CENTRE, BANGARMAU, PRAMOD KUMAR DOHRE, SAYING:
"The patients said that they took medicines from the doctor and he used to charge 10 rupees ($0.15) for it and along with the medicines, he used a syringe as well. He used to inject the same needle on all of them."
Police say they've identified the suspect as Rajendra Kumar, but have been unable to find him.
Local residents say they're worried.
(SOUNDBITE) (Hindi) A LOCAL RESIDENT, VIJAY BAHADUR YADAV, SAYING:
"The entire village should undergo a HIV test. Some people have been found positive. If others are not checked, then it will continue and spread. The whole village should be checked and then the treatment should begin."
A shortage of doctors in India leads many patients to depend on unqualified practitioners.
