We describe the isolation and sequencing of Middle East respiratory syndrome coronavirus (MERS-CoV) obtained from a dromedary camel patient who died laboratory-confirmed MERS-CoV infection after close contact with camels that had rhinorrhea. Nasal swabs collected one his nine were positive for RNA. In addition, was isolated camel. The full genome sequences two isolates identical. Serologic data indicated circulating in but not before human occurred. These suggest this fatal case transmitted...
This cohort descriptive study summarizes the epidemiological, clinical, and laboratory characteristics of Rift Valley fever (RVF) epidemic that occurred in Saudi Arabia from 26 August 2000 through 22 September 2001. A total 886 cases were reported. Of 834 reported for which results available, 81.9% confirmed, 51.1% positive only RVF immunoglobulin M, 35.7% antigen, 13.2% both. The mean age (+/- standard deviation) was 46.9+/-19.4 years, ratio male to female patients 4:1. Clinical features...
A marked increase in the number of cases Middle East respiratory syndrome coronavirus (MERS-CoV) infection occurred Jeddah, Saudi Arabia, early 2014. We evaluated patients with MERS-CoV Jeddah to explore reasons for this and assess epidemiologic clinical features disease.We identified all laboratory-confirmed that were reported Arabian Ministry Health from January 1 through May 16, conducted telephone interviews symptomatic who not health care personnel, we reviewed hospital records. as...
The purpose of this study was to describe the chest CT findings in seven patients with Middle East respiratory syndrome coronavirus (MERS-CoV) infection.The most common finding hospitalized MERS-CoV infection is that bilateral predominantly subpleural and basilar airspace changes, more extensive ground-glass opacities than consolidation. peribronchovascular predilection abnormalities suggestive an organizing pneumonia pattern.
Risk factors for primary Middle East respiratory syndrome coronavirus (MERS-CoV) illness in humans are incompletely understood. We identified all MERS-CoV cases reported Saudi Arabia during March-November 2014 by excluding those with history of exposure to other or acute unknown cause healthcare settings within 14 days before onset. Using a case-control design, we assessed differences underlying medical conditions and environmental exposures among case-patients 2-4 controls matched age, sex,...
Dengue viruses (DENVs) are mosquito-borne which can cause disease ranging from mild fever to severe dengue infection. These endemic in several tropical and subtropical regions. Multiple outbreaks of DENV serotypes 1, 2 3 (DENV-1, DENV-2 DENV-3) have been reported the western region Saudi Arabia since 1994. Strains at least two genotypes DENV-1 (Asia America/Africa genotypes) circulating until 2006. However, all previous studies were based on partial sequencing data envelope (E) gene without...
Middle East respiratory syndrome coronavirus (MERS-CoV) is a novel betacoronavirus that has been circulating in the Arabian Peninsula since 2012 and causing severe infections humans. While bats were suggested to be involved human MERS-CoV infections, direct link between uncertain. On other hand, serological virological data suggest dromedary camels as potential animal reservoirs of MERS-CoV. Recently, we isolated from camel its infected owner provided evidence for transmission patient. Here,...
Abstract Middle East respiratory syndrome coronavirus (MERS-CoV) causes a spectrum of illness. We evaluated whether cycle threshold (Ct) values (which are inversely related to virus load) were associated with clinical severity in patients from Saudi Arabia whose nasopharyngeal specimens tested positive for this by real-time reverse transcription PCR. Among 102 patients, median Ct 31.0 the upstream E gene target 41 (40%) who died was significantly lower than 33.0 61 survivors (p = 0.0087). In...

Approximately 2 to 3 million pilgrims perform Hajj every year. Planning for health care requires knowledge of the pattern diseases, complications, and outcome who require hospitalization during period.In a cross-sectional study we compiled data on all patients admitted 1487 beds in four hospitals Mena (793 beds) three Arafat (694 from seventh thirteenth day season Islamic year 1423, corresponding 8 14 February 2003.Of 808 hospitalized, most (79%) were older than 40 years. There was no sex...
Abstract Healthcare settings can amplify transmission of Middle East respiratory syndrome coronavirus (MERS-CoV), but knowledge gaps about the epidemiology remain. We conducted a retrospective cohort study among healthcare personnel in hospital units that treated MERS-CoV patients. Participants were interviewed exposures to patients, use personal protective equipment, and signs symptoms illness after exposure. Infection status was determined by presence antibodies against MERS-CoV. To assess...
Data on sexually transmitted infections (STIs) in Saudi Arabia (SA) and other Islamic countries are limited. This study describes the results of a five-year surveillance for STIs SA.This is case series descriptive all confirmed diagnosed SA from January, 1995 through December, 1999.A total 39049 were reported to Ministry Health. Reported included nongonococcal urethritis (14557 infections, 37.3%), trichomoniasis (10967 28.1%), gonococcal (5547 14.2%), syphilis (3385 8.7%), human...
Abstract Risk factors for human-to-human transmission of Middle East respiratory syndrome coronavirus (MERS-CoV) are largely unknown. After MERS-CoV infections occurred in an extended family Saudi Arabia 2014, relatives were tested by using real-time reverse transcription PCR (rRT-PCR) and serologic methods. Among 79 relatives, 19 (24%) positive; 11 hospitalized, 2 died. Eleven (58%) positive rRT-PCR; 8 (42%) negative rRT-PCR but serology. Compared with MERS-CoV–negative adult...
During March-May 2014, a Middle East respiratory syndrome (MERS) outbreak occurred in Jeddah, Saudi Arabia, that included many persons who worked or received medical treatment at King Fahd General Hospital. We investigated 78 had laboratory-confirmed MERS during March 2-May 10 and documented contact this hospital. The with comprised 53 patients, 16 healthcare workers, 9 visitors. Among the most probable sites of acquisition were emergency department (22 patients), inpatient areas (17),...
The objective of this study was to assess the validity new dengue classification proposed by World Health Organization (WHO) in 2009 and develop pragmatic guidelines for case triage management. This retrospective involved 357 laboratory-confirmed cases infection diagnosed at King Abdulaziz University Hospital, Jeddah, Saudi Arabia over a 4-year period from 2014 2017. sensitivity identifying severe limited (65%) but higher than old one (30%). It had patients who needed advanced healthcare...
Abstract Background data on HIV epidemiology and preventive measures in Islamic countries is limited.
