Managing infectious disease is among the foremost challenges for public health policy. Interpersonal contacts play a critical role in infectious disease transmission, and recent advances in epidemiological theory suggest a central role for adaptive human behaviour with respect to changing contact patterns. However, theoretical studies cannot answer the following question: are individual respons...
limited success for complications of pandemic (H1N1) 2009 (5). Its broader use in treating critically ill patients has been limited, however, because ECMO requires substantial institutional and multidisciplinary commitment for implementation and is typically only available at major medical centers offering cardiovascular surgery. Although we cannot say specifi cally why our patient survived, cl...
[1] Thermospheric density simultaneously observed by the CHAMP and GRACE satellites in both the pre‐dawn and afternoon local time sectors undergoes significant decrease across both hemispheres during the major stratospheric sudden warming (SSW) in January 2009. This decrease is largest in the equatorial region near the subsolar latitude, reaching ∼30% at 325 km, and 45% at 475 km altitude in th...
OBJECTIVE Yanting County is a high risk area for esophageal cancer (EC) in China. The purpose of this study was to describe the mortality and mortality change of EC from 2004 to 2009 in Yanting County. METHODS EC mortality data from 2004 to 2009 obtained from the Cancer Registry in Yanting were analyzed. Annual percentage changes (APC) were calculated to assess the trends in EC mortality. Age...
In a pandemic setting, surveillance is essential to monitor the spread of the disease and assess its impact. Appropriate mitigation and healthcare preparedness strategies depend on fast and accurate epidemic surveillance data. During the 2009 influenza A(H1N1) pandemic, rapid improvements in influenza surveillance were made in Iceland. Here, we describe the improvements made in influenza survei...
BACKGROUND Pandemic H1N1 2009 influenza virus has been identified as the cause of a widespread outbreak of febrile respiratory infection in the USA and worldwide. We summarised cases of infection with pandemic H1N1 virus in pregnant women identified in the USA during the first month of the present outbreak, and deaths associated with this virus during the first 2 months of the outbreak. METHO...
Astroviruses are globally known enteropathogens causing gastroenteritis and diarrhea, with eight well defined serotypes. Epidemiological studies have recognized serotype-1 as the most common subtype but no such data is available in Pakistan. During 2009-2010, we found astroviruses in 41 out of 535 (7%) samples collected from hospitalized children. Thirty one strains belonged to serotype-1 and c...
Surveys for greater prairie-chickens (Tympanuchus cupido pinnatus) were conducted (includes birds of unknown sex) and located 151 booming grounds. Within survey blocks we observed 0.32 (0.23–0.42) leks/mi 2 and 10.8 (9.6–12.1) males/lek. Approximately 19% fewer leks and 30% fewer males were counted in survey blocks during spring 2009 than during spring 2008. Averages of annual densities observe...
During 2 successive rainy seasons, January 2008 through May 2008 and November 2008 through March 2009, Rift Valley fever virus (RVFV) caused outbreaks in Madagascar. Human and animal infections were confirmed on the northern and southern coasts and in the central highlands. Analysis of partial sequences from RVFV strains showed that all were similar to the strains circulating in Kenya during 20...
Of 233 households with laboratory-confirmed pandemic (H1N1) 2009 in Navarre, Spain, only 64% (107/166) of contacts with influenza-like illness had sought medical care. This value was lower for adults (53%, 39/74) than for children <15 years of age (74%, 68/92), as well as for those with cases secondary to another household case (58%, 64/111).
