Travellers’ diarrhoea, caused by viruses, bacteria or protozoa, is the most common infection experienced by travellers, affect over 20 percent of those who travel to high-risk destinations of the world.
But now it seems that there many be other factors involved in one’s inclination towards or susceptibility to traveller’s diarrhoea – namely, blood type.
A new study, published in The Journal of Clinical Investigation, has found that those with Type A blood are likely to be struck down with travellers’ diarrhoea sooner and more severely. These findings are significant for UK travellers, as nearly half of Brits have type A or AB blood.
Researches gave more than 100 volunteers water containing enterotoxigenic E.coli. The results found that 81% of those with type A blood required medical attention for diarrhoea as a consequence, compared to just 56% in other blood types.
The study concluded that this is due to the way E.coli releases a protein which latches onto the intestinal cells of those with blood type A.
