What are the measures that needs to be taken?
- National Hepatitis Policy– It will translate into better surveillance and detection of water and blood-borne hepatitis viral infections in various regions.
- Availability of safe and potable water, early screening, vaccination and prevention of misuse of disposable needles and syringes will help to eliminate treatable viral hepatitis.
- Easy availability of the newly discovered drugs at a reasonable price.
- Hepatitis B birth dose, given in the first 24 hours, helps prevent vertical transmission from the mother to child.
There is also a need to increase awareness about WHO recommendation that allows hepatitis B open-vial policy. Opened vials of hepatitis B vaccine can be kept for a maximum duration of 28 days for use in other children if the vaccine meets certain conditions. So, bigger vials like 10 dose vials can be used in an interval of 28 days, thus increasing vaccine availability.
