India has 33 JCI accredited hospitals. However, for a patient who needs to get a treatment should look for the hospital which has that particular section? Once the treatment is over, the patient can stay in the hospital for recovery or even opt for a PG near to the hospital premises. Many hospitals also offer the alternative of continuing the treatment through tele-medicine.
The government understands the process on the global level so tourist visas for the patients have no restrictions. Even there is on arrival visa for a number of countries so that people can come to India for a period of thirty days for their medical issues. In 2016, the maximum number of citizens of Bangladesh, Afghanistan, Maldives, Republic of Korea and Nigeria came to India for medical treatments.
When we talk about India, it is a multi-cultural country and there are a number of languages but the most commonly used language is English. So for the foreign nationals, language is not a problem as in medical profession people speak English fluently and for the patients, there is no issue.
Thus, these are some of the reasons which make people visit India especially in concern to medical issues.
