Biosecurity measures to reduce influenza infections in military barracks in Ghana.

Background: Military barracks in Ghana have backyard poultry populations but the methods used here involve low biosecurity measures and high risk zoonosis such as avian influenza A viruses or Newcastle disease. We assessed biosecurity measures intended to minimize the risk of influenza virus infection among troops and poultry keepers in military barracks.

Findings: We educated troops and used a questionnaire to collect information on animal populations and handling practices from 168 individuals within 203 households in military barracks.

Serological evidence of flaviviruses infection among acute febrile illness patients in Afghanistan.

Introduction: Current published reports on the causative agents of acute febrile illness (AFI) in Afghanistan are scarce, and the burden of disease due to flaviviruses is unknown.

Methodology: A hospital-based surveillance study for AFI was established in 2008 through 2010 to determine the seroepidemiology of West Nile virus (WNV), tick-borne encephalitis virus (TBEV) and dengue viruses (DENV) using commercial ELISA kits. Due to major logistical challenges, only acute sera were collected.

Enteric fever burden in North Jakarta, Indonesia: a prospective, community-based study.

Introduction: We undertook a prospective community-based study in North Jakarta, Indonesia, to determine the incidence, clinical characteristics, seasonality, etiologic agent, and antimicrobial susceptibility pattern of enteric fever.

Methodology: Following a census, treatment centre-based surveillance for febrile illness was conducted for two-years. Clinical data and a blood culture were obtained from each patient.

Building military influenza surveillance capacity in West Africa.

Militaries are especially susceptible to operationally important outbreaks of acute respiratory infections such as pandemic and seasonal influenza. In addition, militaries play important roles for State Parties working to meet International Health Regulations 2005, particularly in developing countries. In 2009, the U.

Delayed 2009 pandemic influenza A virus subtype H1N1 circulation in West Africa, May 2009-April 2010.

To understand 2009 pandemic influenza A virus subtype H1N1 (A[H1N1]pdm09) circulation in West Africa, we collected influenza surveillance data from ministries of health and influenza laboratories in 10 countries, including Cameroon, from 4 May 2009 through 3 April 2010. A total of 10,203 respiratory specimens were tested, of which 25% were positive for influenza virus. Until the end of December 2009, only 14% of all detected strains were A(H1N1)pdm09, but the frequency increased to 89% from January through 3 April 2010.

Troop education and avian influenza surveillance in military barracks in Ghana, 2011.

Background: Influenza A viruses that cause highly pathogenic avian influenza (HPAI) also infect humans. In many developing countries such as Ghana, poultry and humans live in close proximity in both the general and military populations, increasing risk for the spread of HPAI from birds to humans. Respiratory infections such as influenza are especially prone to rapid spread among military populations living in close quarters such as barracks making this a key population for targeted avian influenza surveillance and public health education.

Etiology of acute, non-malaria, febrile illnesses in Jayapura, northeastern Papua, Indonesia.

We conducted a prospective, inpatient fever study in malaria-endemic Papua, Indonesia to determine non-malaria fever etiologies. Investigations included malaria blood films, blood culture, paired serologic samples analysis for dengue, Japanese encephalitis, leptospirosis, scrub typhus, murine typhus, and spotted fever group rickettsia. During 1997-2000, 226 patients (127 males and 99 females) 1-80 years of age (median age = 25 years) were enrolled.

The burden of diarrhoea, shigellosis, and cholera in North Jakarta, Indonesia: findings from 24 months surveillance.

Background: In preparation of vaccines trials to estimate protection against shigellosis and cholera we conducted a two-year community-based surveillance study in an impoverished area of North Jakarta which provided updated information on the disease burden in the area.

Methods: We conducted a two-year community-based surveillance study from August 2001 to July 2003 in an impoverished area of North Jakarta to assess the burden of diarrhoea, shigellosis, and cholera. At participating health care providers, a case report form was completed and stool sample collected from cases presenting with diarrhoea.

Antimicrobial resistance of bacterial pathogens associated with diarrheal patients in Indonesia.

The antimicrobial susceptibility patterns for 2,812 bacterial pathogens isolated from diarrheal patients admitted to hospitals in several provinces in the cities of Jakarta, Padang, Medan, Denpasar, Pontianak, Makassar, and Batam, Indonesia were analyzed from 1995 to 2001 to determine their changing trends in response to eight antibiotics: ampicillin, trimethoprim-sulfamethoxazole, chloramphenicol, tetracycline, cephalothin, ceftriaxone, norfloxacin, and ciprofloxacin. Vibrio cholerae O1 (37.1%) was the pathogen most frequently detected, followed by Shigella spp.

Surveillance of bacterial pathogens of diarrhea disease in Indonesia.

Emerging or reemerging infections due to bacterial disease may be a local, regional or global problem. Bacterial acute gastroenteritis is a potential cause of substantial morbidity in travelers and deployed U.S.

Enteropathogens associated with acute diarrhea in community and hospital patients in Jakarta, Indonesia.

The prevalence of bacteria, parasite and viral pathogens in 3875 patients with diarrhea in community and hospital settings from March 1997 through August 1999 in Jakarta, Indonesia was determined using routine bacteriology and molecular assay techniques. Bacterial pathogens isolated from hospital patients were, in decreasing frequency, Vibrio cholerae O1, Shigella flexneri, Salmonella spp. and Campylobacter jejuni, while S.

Spectrum of vibrio species associated with acute diarrhea in North Jakarta, Indonesia.

Vibrio spp was isolated from 1024 (21.2%) of 4820 diarrhea patients admitted to a community hospital in North Jakarta from 1996 through 1998. Vibrio cholerae O1 (49.
