In May 1995, an international team characterized and contained outbreak of Ebola hemorrhagic fever (EHF) in Kikwit, Democratic Republic the Congo. Active surveillance was instituted using several methods, including house-to-house search, review hospital dispensary logs, interview health care personnel, retrospective contact tracing, direct follow-up suspect cases. field, a clinical case defined as signs, plus with case-patient, or at least 3 10 symptoms. A total 315 cases EHF, 81% fatality,...
BackgroundIn May 2022, several countries with no history of sustained community transmission mpox (formerly known as monkeypox) notified WHO new cases. These cases were soon followed by a large-scale outbreak, which unfolded across the world, driven local, in-country within previously unaffected countries. On July 23, declared outbreak Public Health Emergency International Concern. Here, we aim to describe main epidemiological features this largest reported date.MethodsIn analysis global...
Abstract. Following an outbreak of Rift Valley fever (RVF) in south‐eastern Mauritania during 1998, entomological investigations were conducted for 2 years the affected parts Senegal and Mauritania, spanning Sénégal River basin. A total 92 787 mosquitoes (Diptera: Culicidae), belonging to 10 genera 41 species, captured light traps. In Senegal, Culex poicilipes (41%) Mansonia uniformis (39%) most abundant species caught, whereas Aedes vexans (77%) Cx. (15%) predominated Mauritania. RVF virus...
Abstract From February to August 2003, 38 persons were infected with Crimean-Congo hemorrhagic fever (CCHF) virus in Mauritania; 35 of these residents Nouakchott. The first patient was a young woman who became ill shortly after butchering goat. She transmitted the infection 15 hospital where she admitted and four members her family. In Nouakchott, two disease clusters 11 isolated cases identified. case-fatality ratio 28.6%. Of patients not by case-patient, almost half butchers, which...
Antibodies to Plasmodium falciparum C-terminal merozoite surface protein 1 (PfMSP-1p19) have been correlated with protection against malaria, but this association may apply many antigens. To address question, we conducted a prospective serological study of 205 individuals in an active 5-month clinical survey Senegalese village where malaria is mesoendemic. Before the 2000 rainy season, antibody responses specific for recombinant baculovirus PfMSP-1p19 or extracts were compared 2 vitro...
Objectives: To assess overall resistance rates and risk factors for to ampicillin, co-amoxiclav, nalidixic acid, fluoroquinolones trimethoprim/sulfamethoxazole in Escherichia coli strains isolated from outpatients with acute urinary tract infection Dakar (Senegal).
Abstract In October 2003, 9 human cases of hemorrhagic fever were reported in 3 provinces Mauritania, West Africa. Test results showed acute Rift Valley virus (RVFV) infection, and a field investigation found recent circulation RVFV with prevalence rate 25.5% (25/98) 4 deaths among the 25 laboratory-confirmed case-patients. Immunoglobulin M against was 46% (25/54) domestic animals. also isolated from mosquito species Culex poicilipes. Genetic comparison virion segments indicated little...
A Rift Valley fever outbreak occurred in Mauritania 1998. Seroepidemiologic and virologic investigation showed active circulation of the virus, with 13 strains isolated, 16% (range 1.5%-38%) immunoglobulin (Ig) M-positivity sera from 90 humans 343 animals (sheep, goats, camels, cattle, donkeys). One human case was fatal.
It is a challenge in low-resource settings to ensure the availability of complete, timely disease surveillance information. Smartphone applications (apps) have potential enhance data transmission. The Central African Republic (CAR) Ministry Health and Médecins Sans Frontières (MSF) conducted 15-week pilot project test app, Argus, for 20 conditions 21 health centers Mambéré Kadéi district (MK 2016). Results were compared usual paper-based MK year prior 2015) simultaneously an adjacent...
ABSTRACT Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease that may also be transmitted through person-to-person transmission by exposure to infected body fluids. Despite its wide geographic distribution in animals, CCHF virus rarely associated with recognized human diseases. We report the first case of imported France.
Background: Data regarding the evolution of antimicrobial resistance are needed to suggest appropriate empirical treatment urinary tract infections (UTI) in developing countries. To assess susceptibility Escherichia coli, predominant pathogen community-acquired UTI, a prospective multicenter study was carried out Dakar, Senegal. Methodology: From February 2004 October 2006, 1010 non-duplicate E. coli strains were collected from four centres. Antimicrobial testing performed using disk...
To the Editor: Crimean-Congo hemorrhagic fever (CCHF) virus, genus Nairovirus, family Bunyviridae, is transmitted to mammals and birds by ticks. Hyalomma ticks, primary vectors in CCHF transmission, are widespread throughout Europe, Asia, Middle East, Africa; evidence of virus has been found all these regions. humans an acute viral disease that bite infected direct contact with blood or tissues from viremic animals, secretions person (1). On January 26, 2003, a 22-year-old shepherd was...
Abstract Background Over the past four decades, drought episodes in Eastern Mediterranean Region (EMR) of World Health Organization (WHO) have gradually become more widespread, prolonged and frequent. We aimed to map hotspot countries identified key strategic actions for health consequences. Methods reviewed scientific literature WHO EMR documentation on trends patterns consequences from 1990 through 2019. Extensive communication was also carried out with country offices retrieve information...
The 2022-2023 mpox outbreak predominantly affected adult men; 1.3% of reported cases were in children and adolescents <18 years age. Analysis global surveillance data showed 1 hospital intensive care unit admission 0 deaths that age group. Transmission routes clinical manifestations varied across subgroups.
Data on the seroepidemiology of rubella in tropical African countries are still scarce. To determine seroprevalence Senegal, we conducted a 6 year retrospective survey among women child bearing age urban region Dakar, Senegal. The global determined with commercial enzyme immunoassay 3471 serological results was 90.1%. distribution this prevalence appeared stable no significant difference between years study, groups, and socio-economic level districts residence patients. Compared to...
During a four-year study (1987-1990) at the Neonatal Department, University Hospital Pointe-à-Pitre (French West Indies), blood culture was systematically performed on all admitted newborns. The incidence of septicemia 48 1000 admissions and 8.9 inborn live births. Among 107 neonatal positive cultures, group B streptococcus accounted for 37% isolates most frequent cause septicemia. overall mortality rate 8.4%. bacterial among high rates reported in literature. is discussed as public health...
