Crimean-Congo haemorrhagic fever (C-CHF) re-emerged recently in the United Arab Emirates. The clinical outcome of 11 cases of viral haemorrhagic fever patients admitted to hospital between June 1994 and January 1995 is described. Four cases were laboratory confirmed retrospectively as C-CHF, the other patients were diagnosed likely to have the same disease on epidemiological and clinical grounds. In 72.7% of the patients, infection was fatal. Symptoms started 3.5 days before hospitalization. On admission, 81.8% of patients had high fever, 45.5% were vomiting, 63.6% had diarrhoea, 45.5% had haemorrhagic signs, and 18.2% had throat pain. Fatalities occurred 6.8 days after admission. Survivors were hospitalized for 9.3 days. Nosocomial transmission was not observed.

Improved methods of bacterial detection including isolate serotyping must be made available in order to further reduce mortality and morbidity from meningitis.

The aim of this study was to establish the carrier rate of group A beta haemolytic streptococci in school children in Al Ain, United Arab Emirates. One thousand and two randomly selected school children aged 5-7 years had their throats swabbed twice for both culture and direct antigen detection of group A streptococci. One hundred and fourteen children (11.3%) had both a positive antigen and culture test, while 216 (21.6%) had antigen-positive tests only and 16 (1.5%) had a positive culture only. Thus, the combination of culture and antigen detection revealed a carrier rate of 35.4% in the children examined. We conclude that in an affluent but isolated desert area on the Tropic of Cancer, group A streptococcal carriage rate is high. Antigen detection is superior to culture techniques in asymptomatic carrier studies.

There is a positive correlation between Helicobacter pylori infection and chronic active gastritis, peptic ulcer and gastric cancer and maltoma. There is little information on H. pylori profiles in farmers and non-farmers in the literature. Our main objective was to study the H. pylori profiles in farmers and non-formers in the United Arab Emirates. A prospective study of 151 subjects - 76 farmers and 75 non-farmers - was undertaken by determining their IgG and IgA H. pylori antibody profiles in their serum samples. Data on lifestyle were obtained from them. Eligible subjects were those who had engaged in farming for at least five years and who had not received an anti-H. pylori treatment during the six months prior to admission into the study. Most of the farmers lived in less modern accommodation, were less educated, ate their vegetable products unwashed, did not have drinking water facilities, when compared to non-farmers. Helicobacter pylori serology by IgG and IgA was positive in 112 and 77 subjects respectively (p < 0.0001). The sensitivity values for IgG and IgA serology tests were 74.2 and 51.0% respectively (p < 0.001). There were 59 and 42 H. pylori-positive farmers by IgG and IgA H. pylori serology tests respectively (p < 0.001). Among the non-farmers, the corresponding figures were 53 and 25 (p < 0.01), and neither IgG nor IgA (p = 0.4), respectively. The H. pylori serology test was able to differentiate between farmers and non-farmers. When the discordant values between IgG and IgA tests were computed for each group of subjects, the difference was significant for both farmers and non-farmers (p < 0.001 in each case). There was no difference between the farmers and non-farmers in respect of their H. pylori profiles. The farmers have a lower standard of living than non-farmers.
