LONDON, ENGLAND, March 8, 2004: Tourists to India and other tropical countries could enjoy their holidays there more now without the fear of being afflicted by “Delhi Belly,” the bug that causes diarrhoea. According to statistics available, British travellers are the worst affected because most of them do not wash their hands. Now, even these tourists would get protection. Scientists have developed a vaccine Dukorai, which is expected to be in the market within a year. It is an oral vaccine, which is to be taken as a drink in two doses at least a week before departure and provides up to three months’ protection against infection by enterotoxigenic E.coli. Dukorai also acts against cholera. A study published in Lancet showed just over half of all visitors to Kenya and India developed diarrhoea. The vaccine, developers claim, could offer nearly foolproof protection.
