PROBLEM The revision of the International Health Regulations (IHR) and the threat of influenza pandemics and other disease outbreaks with a major impact on developing countries have prompted bolstered surveillance capacity, particularly in low-resource settings. APPROACH Surveillance tools with well-timed, validated data are necessary to strengthen disease surveillance. In 2007 Madagascar imp...

OBJECTIVE To compare sentinel and population-based surveillance of the effect of seven-valent pneumococcal conjugate vaccine (PCV7), introduced in 2000, on the hospitalization of children aged under 5 years with invasive pneumococcal disease (IPD) in the United States of America. METHODS Population surveillance data were used to identify children hospitalized between 1998 and 2006 with IPD ca...

Annual estimates of the influenza disease burden provide information to evaluate programs and allocate resources. We used a multiplier method with routine population-based surveillance data on influenza hospitalization in the United States to correct for under-reporting and estimate the burden of influenza for seasons after the 2009 pandemic. Five sites of the Influenza Hospitalization Surveill...

The Indian Council of Medical Research (ICMR) undertook screening of asymptomatic persons from high risk group with the ELISA test for HIV infection in 1986 and found that HIV infection has reached India. ICMR in collaboration with the central and State health services initiated the national sero-surveillance programme for HIV infection in 43 surveillance and five reference centres to determine...

Adequate surveillance of hard-to-reach and 'hidden' subpopulations is crucial to containing the HIV epidemic in low prevalence settings and in slowing the rate of transmission in high prevalence settings. For a variety of reasons, however, conventional facility and survey-based surveillance data collection strategies are ineffective for a number of key subpopulations, particularly those whose b...

PROBLEM Evaluation of influenza surveillance systems is poor, especially in Africa. APPROACH In 2007, the Institut Pasteur de Madagascar and the Malagasy Ministry of Public Health implemented a countrywide system for the prospective syndromic and virological surveillance of influenza-like illnesses. In assessing this system's performance, we identified gaps and ways to promote the best use of...

The sentinel surveillance of blood borne virus testing began in 2002, with the aim of supplementing the routine surveillance of hepatitis. Information on the testing carried out in participating centres is collected irrespective of test result and can therefore also be used as a basis for estimating prevalence among those tested. These data have enhanced our knowledge and understanding of hepat...

CONTEXT This study assessed differences in the effort and resources needed to recruit clinicians for a shortterm infectious disease sentinel surveillance project. OBJECTIVE Measure differences in recruitment efficiency, time to obtain informed consent, and compliance to a Web-based demographic survey between 3 physician groups. DESIGN We recruited Wisconsin clinicians by e-mail, phone, or f...

Passive surveillance of infectious diseases with a high percentage of asymptomatic cases or long incubation periods, such as acquired immunodeficiency syndrome (AIDS), does not reflect the current transmission dynamics. Thus, a multi-strategic surveillance, such as the human immunodeficiency virus (HIV) sentinel surveillance proposed by the World Health Organization (WHO), is necessary. The Bra...

BACKGROUND Rubella during pregnancy can cause serious fetal abnormalities and death. Peru has had integrated measles/rubella surveillance since 2000 but did not implement congenital rubella syndrome (CRS) surveillance until 2004, in accordance with the Pan American Health Organization recommendations for rubella elimination. The article describes the experience from the CRS sentinel surveillanc...
