Vaccination for Travel
According to BBC News website on 24 October 2017, WHO announced nine-in-10 cases of typhoid fever were prevented by a new vaccine. It gives a “huge impact” on the patients of typhoid fever. 22 million cases of typhoid fever were occurred and 220,000 deaths each year. This new vaccine may release from the infection especially children and eliminate the infection from countries. Salmonella Typhi, the bacteria that is cause of typhoid fever, are highly contagious and spread through contaminated food and water. If you are infected by the bacteria, patients may have prolonged fever, headache, nausea, loss of appetite, and constipation, and in one-in-100 cases, patients may be in serious condition. At this point, the new vaccine is in medical trial by the University of Oxford, and they have got up to 87% effective result. The result reported in the Lancet medical journal last month.
