Progress toward poliomyelitis eradication in Nigeria.

Background: Transmission of wild poliovirus (WPV) has never been interrupted in Afghanistan, Pakistan, and Nigeria. Since 2003, infections with WPV of Nigerian origin have been detected in 25 polio-free countries. In 2012, the Nigerian government created an emergency operations center and implemented a national emergency action plan to eradicate polio.

Outreach to underserved communities in northern Nigeria, 2012-2013.

Background: Persistent wild poliovirus transmission in Nigeria constitutes a major obstacle to global polio eradication. In August 2012, the Nigerian national polio program implemented a strategy to conduct outreach to underserved communities within the context of the country's polio emergency action plans.

Methods: A standard operating procedure (SOP) for outreach to underserved communities was developed and included in the national guidelines for management of supplemental immunization activities (SIAs).

Polio eradication in Nigeria and the role of the National Stop Transmission of Polio program, 2012-2013.

To strengthen the Nigeria polio eradication program at the operational level, the National Stop Transmission of Polio (N-STOP) program was established in July 2012 as a collaborative effort of the National Primary Health Care Development Agency, the Nigerian Field Epidemiology and Laboratory Training Program, and the US Centers for Disease Control and Prevention. Since its inception, N-STOP has recruited and trained 125 full-time staff, 50 residents in training, and 50 ad hoc officers. N-STOP officers, working at national, state, and district levels, have conducted enumeration outreaches in 46,437 nomadic and hard-to-reach settlements in 253 districts of 19 states, supported supplementary immunization activities in 236 districts, and strengthened routine immunization in 100 districts.

Ebola virus disease outbreak - Nigeria, July-September 2014.

On July 20, 2014, an acutely ill traveler from Liberia arrived at the international airport in Lagos, Nigeria, and was confirmed to have Ebola virus disease (Ebola) after being admitted to a private hospital. This index patient potentially exposed 72 persons at the airport and the hospital. The Federal Ministry of Health, with guidance from the Nigeria Centre for Disease Control (NCDC), declared an Ebola emergency.

Case control study to identify risk factors for acute hepatitis C virus infection in Egypt.

Background: Identification of risk factors of acute hepatitis C virus (HCV) infection in Egypt is crucial to develop appropriate prevention strategies.

Methods: We conducted a case-control study, June 2007-September 2008, to investigate risk factors for acute HCV infection in Egypt among 86 patients and 287 age and gender matched controls identified in two infectious disease hospitals in Cairo and Alexandria. Case-patients were defined as: any patient with symptoms of acute hepatitis; lab tested positive for HCV antibodies and negative for HBsAg, HBc IgM, HAV IgM; and 7-fold increase in the upper limit of transaminase levels.

Epidemiology and risk factors for endemic typhoid fever in Uzbekistan.

Background: To investigate the risk factors for infection with endemic typhoid fever in the Samarkand region of Uzbekistan.

Methods: Case-control study of culture-confirmed bloodstream infection with Salmonella Typhi. Patients were compared to age-matched community controls.

Evolution of infection control in Egypt: achievements and challenges.

Background: The high prevalence of hepatitis C virus (HCV) infection in Egypt highlighted the urgent need for implementing infection control (IC) programs in Egypt.

Objectives: The Ministry of Health and Population (MOHP), in collaboration with the US Naval Medical Research Unit No. 3, and the World Health Organization (WHO), developed a national plan to initiate an IC program with the objectives of improving quality of care and reducing transmission of hospital-acquired infections.

Population-based surveillance of typhoid fever in Egypt.

Credible measures of disease incidence are necessary to guide typhoid fever control efforts. In Egypt, incidence estimates have been derived from hospital-based syndromic surveillance, which may not represent the population with typhoid fever. To determine the population-based incidence of typhoid fever in Fayoum Governorate (pop.

Rapid diagnosis of typhoid fever by enzyme-linked immunosorbent assay detection of Salmonella serotype typhi antigens in urine.

We developed and evaluated an enzyme-linked immunosorbent assay (ELISA) using monoclonal antibodies to capture somatic antigen 9 (O9), flagellar antigen d (Hd), and the Vi capsular polysaccharide antigen (Vi) from the urine of persons with and without typhoid fever. Sequential urine samples were collected from 44 patients with blood culture-confirmed typhoid fever and from two control groups. The first control group included patients with brucellosis (n = 12) and those with clinically diagnosed, non-typhoid, acute, febrile illness (n = 27).

Occupational exposure to needlestick injuries and hepatitis B vaccination coverage among health care workers in Egypt.

Background: The health care worker (HCW) is at substantial risk of acquiring bloodborne pathogen infections through exposure to blood or infectious body fluids. Hepatitis B vaccination of HCWs and optimal HCW practices regarding management of sharps can minimize these risks. This study explores the frequency of exposure to needlestick injuries and the hepatitis B vaccination coverage among HCWs in Egypt.

Estimating the incidence of typhoid fever and other febrile illnesses in developing countries.

To measure the incidence of typhoid fever and other febrile illnesses in Bilbeis District, Egypt, we conducted a household survey to determine patterns of health seeking among persons with fever. Then we established surveillance for 4 months among a representative sample of health providers who saw febrile patients. Health providers collected epidemiologic information and blood (for culture and serologic testing) from eligible patients.

Overview of injection practices in two governorates in Egypt.

Objective: To describe the extent and characteristics of injection use and injection providers in Egypt, given that unsafe injections are associated with blood-borne pathogen transmission.

Methods: Household surveys of a population-based sample of residents in the Nile Delta and in Upper Egypt; focus group discussions and in-depth interviews with community target groups, formal and informal medical providers.

Results: Of 4197 persons interviewed, 26.

Trends of multiple-drug resistance among Salmonella serotype Typhi isolates during a 14-year period in Egypt.

A total of 853 isolates of Salmonella serotype Typhi recovered from patients with typhoid fever who were admitted to a major infectious disease hospital in Cairo, Egypt, from 1987 through 2000 underwent antibiotic susceptibility testing to determine multiple-drug resistance. The observed resurgence of chloramphenicol susceptibility (P=.002) may suggest reuse of this drug for the treatment of typhoid fever in Egypt.
