![]() ![]() Any country has adopted public health actions related to treatment of infected population or to prevent the infection, at least in population with more risk. pylori infection and the possibility of suffer from peptic ulcer disease, and specially gastric neoplasm. The existence of a human reservoir of infection, the possibility of reinfection and transmission person to person, especially in domestics areas, should condition the adoption of preventive measures to reduce the prevalence of H. We can consider that the improvement in health status of population has been enough to reduce dramatically HAV infection but insufficient to control infection with H. ![]() In our population, despite an admissible health level, we detected a significant seroprevalence of infection by H. The low overall seroprevalence of HAV infection (3.2%) may suggest an appropriate sanitary level in population studied and, and according to some researchers, a low risk of infection by fecal-oral route, including infection by H. We compared prevalence of both infections by McNemar's test, with significant results (p < 0.0005), showing that they were very different. The seroprevalence of HAV infection was low in both the population infected with H. pylori (95.8%) showed negative serology for VHA. Most students with positive serology for H. Serology was negative for both infections in 144 cases (65.4%) and positive in 3 cases (1.3%). pylori and against HAV in 72 (32.7%) and in 7 (3.2%) students severally. No students had suffered from gastro-duodenal ulcer or HAV infection or had been vaccinated against this virus. We investigated simultaneously the presence of antibodies to H. We excluded students from different geographical areas. We included 220 undergraduates, 163 women and 57 men, with ages between 18 and 23 years (21.3 average age), who join our hospital, to start or continue studies of medicine or nursering. pylori in a potentially homogeneous population: young adult, naturals and residents in Western Andalusia (Seville, Huelva and Cádiz) and with a socio-sanitary level allegedly medium-high. This review does not include any studies completed in Spain, which motivates this posting to share our experience in this area.ĭuring 2004-2007 we investigated the presence of IgG antibodies against VHA and H. The conclusion of this systematic review is that the comparison of seroprevalence of both infections is not a conclusive method of evaluation fecal-oral transmission in the infection by H. pylori and HAV infections, the meaning of these researches is being questioned. In recent reviews of studies comparing the seroprevalence of H. ![]() pylori infection when the prevalence of this infection is relatively important respect to prevalence of HAV infection, and when any relationship is not detected, in a certain population and in different age groups, between the prevalence of both infections (7-9). Fecal-oral transmission would have little value in H. pylori infection has been valued by some researchers, comparing in certain populations the prevalence of both infections. The impact of fecal-oral transmission in H. The prevalence of VHA infection has been considered by some researchers as an indirect marker for risk of infection by fecal-oral contamination of water or food or health level of a population. The prevalence of this disease has fallen down because of the improvement in sanitary conditions of the population. (5) The fecal-oral route is the main mechanism of transmission of infection of hepatitis A virus (HAV) (6). This transmission, from person to person, probably has a very important role in communities or countries with low socio-health level through overcrowding, or sharing bedrooms and bathrooms, etc. In countries or communities with a good social and health level, we must support different transmissions mechanisms, not yet well clarified, from person to person at various levels: domestic, in nurseries or in closed institutions, by oral-oral line (saliva), gastro-oral way (vomits) or fecal-oral. It is also believed that the main way of transmission in countries with low health is the contamination in drinking water and food (5). The most accepted mechanism of disease transmission is fecal-oral route. pylori) infection is a very common disease, especially in developing countries, affecting 80-90% of the adult population and 30% in the younger population (1-4).
