Hospitals in India are required by law to screen any donated blood for HIV among other diseases. When a patient goes to a doctor or hospital for treatment, they place their trust in the doctors and nurses who treat them, putting their health and well-being in their hands. The neglect to follow proper protocol and put patients in direct danger not only violates the law, but the trust that inherently exists between healthcare professional and patient.
Infecting patients with HIV, whether intentional or not, was surely preventable somehow. The medical staff directly responsible for the infections should of course be punished. But hospital directors should be held accountable too. They either failed to ensure the safety of the medical equipment that caused the infections or did not adequately supervise the staff responsible.
Although it is possible for accidents to happen, HIV is such a serious disease with no known cure that all preventative measures should have been taken. Tests should have been conducted twice over and results should have been verified. Failure to do so was gross negligence on the part of the directors and they should face criminal charges for it.
Infecting patients with HIV is one of the worst things that I've ever heard about a hospital. The people in India do not have a lot of options when it comes to healthcare unless they are wealthy, so it is even more despicable that the hospital directors would do this.
