An outbreak of oseltamivir-resistant influenza A (H1N1) occurred in a long-term care facility. Eight (47%) of 17 and 1 (6%) of 16 residents in 2 wards had oseltamivir-resistant influenza A virus (H1N1) infections. Initial outbreak response included treatment and prophylaxis with oseltamivir. The outbreak abated, likely because of infection control measures.

An outbreak of tuberculosis (TB) in Italy involved 19 schoolchildren with active TB and 43 with latent infection. The source of the outbreak was a school assistant born in Italy who had a family history of TB. This outbreak highlights the need for maintaining clinical and public health expertise in countries with low TB incidence.

During an outbreak of severe acute respiratory infections in 2 orphanages, Vietnam, 7/12 hospitalized children died. All hospitalized children and 26/43 children from outbreak orphanages tested positive for rhinovirus versus 9/40 control children (p = 0.0005). Outbreak rhinoviruses formed a distinct genetic cluster. Human rhinovirus is an underappreciated cause of severe pneumonia in vulnerable...

Salmonella Typhi infections are important public health problems for the developing countries. In this study we investigated the molecular epidemiology of a suspected well-water borne S. Typhi outbreak occurred in a district of Malatya-Turkey. This outbreak affected 10 patients in two days. Arbitrary primed polymerase chain reaction (AP-PCR) based typing showed two clones, one had seven, and th...

AIM To evaluate the NSW enteric disease outbreak surveillance system. EVALUATION METHODS We performed unstructured interviews with NSW Health Communicable Diseases Branch staff and analysed summary outbreak reports for July 2000 to June 2005. PERFORMANCE OF THE SURVEILLANCE SYSTEM: The system provided a mechanism for meeting all of its objectives to some level. Limitations included difficulty...

BACKGROUND Rapid response to outbreaks of emerging infectious diseases is impeded by uncertain diagnoses and delayed communication. Understanding the effect of inefficient response is a potentially important contribution of epidemic theory. To develop this understanding we studied societal learning during emerging outbreaks wherein patient removal accelerates as information is gathered and diss...

A swine influenza outbreak occurred on a commercial pig farm in Thailand. Outbreak investigation indicated that pigs were co-infected with pandemic (H1N1) 2009 virus and seasonal influenza (H1N1) viruses. No evidence of gene reassortment or pig-to-human transmission of pandemic (H1N1) 2009 virus was found during the outbreak.

A newly identified diary from a soldier in 1918 describes aspects of a troop ship outbreak of pandemic influenza. This diary is the only known document that describes this outbreak and provides information not officially documented concerning possible risk factors such as overcrowding and the suboptimal outbreak response by military leaders. It also presents an independent personal perspective ...

In August 2011, an anthrax outbreak occurred among Hippopotamus amphibius hippopotamuses and humans in Zambia. Here, we report the draft genome sequence of the Bacillus anthracis outbreak strain CZC5, isolated from tissues of H. amphibius hippopotamuses that had died in the outbreak area.

An outbreak of influenza B occurred in December 1996 on an oil rig in Darwin Harbour. The outbreak affected 56% of the workers on the rig. An outbreak in December is outside the usual Australian influenza season of June to September, but is consistent with other tropical regions, where outbreaks can occur throughout the year. Influenza vaccination could prevent similar outbreaks in confined wor...
