Information about the virus will be posted on the health ministry's website."Though there is no vaccine or curative therapy for Ebola virus disease, I want to apprise this House that outbreaks can be contained through early detection and isolation of cases, contact tracing and monitoring, and following rigorous procedures for infection control, if such cases were to report in our country," Mr Vardhan said.
