BACKGROUND Concerns have been raised about how the transmission of emerging infectious diseases from patients to healthcare workers (HCWs) and vice versa could be recognized and prevented in a timely manner. An effective strategy to block transmission of pandemic H1N1 (2009) influenza in HCWs is important. METHODOLOGY/PRINCIPAL FINDINGS An infection control program was implemented to survey a...
Influenza viruses cause annual epidemics and occasional pandemics that have claimed the lives of millions. The emergence of novel strains continues to challenge the public health and scientific communities. Recent outbreaks of highly pathogenic avian influenza A virus infections (including those of the H5N1 subtype) in poultry and in humans (through contact with infected birds), since 2003, hav...
A novel H1N1 influenza A virus emerged in April 2009, and rapidly reached pandemic proportions. We report a retrospective observational case study of pathologic findings in 8 patients with fatal novel H1N1 infection at the University of Michigan Health Systems (Ann Arbor) compared with 8 age-, sex-, body mass index-, and treatment-matched control subjects. Diffuse alveolar damage (DAD) in acute...
Although infections with the novel pandemic 2009 influenza A (H1N1) virus (A/H1N1/2009) appeared to be relatively mild during the first summer of circulation ('off season'), there has been significant morbidity and hospitalization and several fatal cases. Thus, rapid detection of A/H1N1/2009 is crucial for efficient treatment and infection control measures. In contrast to seasonal influenza, wh...
Background: Saudi Arabia hosted 2.5 million pilgrims in 2009 amidst H1N1 pandemic. The Armed Forces Hospital in Mina caters for pilgrims during Hajj, annually. In the hospital, rigorous infection control precautions were taken to mitigate the transmission of the pandemic among the care seekers and the hospital’s health workers. Objective: To study the distribution of confirmed H1N1 infection am...
Recent reports of mild to severe influenza-like illness in humans caused by a novel swine-origin 2009 A(H1N1) influenza virus underscore the need to better understand the pathogenesis and transmission of these viruses in mammals. In this study, selected 2009 A(H1N1) influenza isolates were assessed for their ability to cause disease in mice and ferrets and compared with a contemporary seasonal ...
In 2009, a novel swine-origin H1N1 influenza virus emerged in Mexico and quickly spread to other countries, including China. This 2009 pandemic H1N1 can cause human respiratory disease, but its pathogenesis remains poorly understood. Here, we studied the infection and pathogenesis of a new 2009 pandemic strain, A/Wenshan/01/2009 H1N1, in China in human airway epithelial cell lines compared with...
The global population has been exposed to the novel pandemic H1N1 influenza virus since mid March 2009, causing the expansion of respiratory illness around the world, including Thailand. To evaluate the antibody titers against human pandemic influenza (H1N1) in Thai people with influenza-like illness (ILI), 45 paired serum samples (acute and convalescent) were subjected to hemagglutination inhi...
BACKGROUND A novel 2009 swine-origin influenza A H1N1 virus (S-OIV H1N1) has been transmitted among humans worldwide. However, the pathogenesis of this virus in human airway epithelial cells and mammals is not well understood. METHODOLOGY/PRINCIPAL FINDING In this study, we showed that a 2009 A (H1N1) influenza virus strain, A/Beijing/501/2009, isolated from a human patient, caused typical in...
