Triple-Reassortant Swine Influenza A (H1) in Humans in the United States, 2005–2009

TLDR
From December 2005 until just before the current human epidemic of swine-origin influenza viruses, there was sporadic infection with triple-reassortant swine influenza A (H1) viruses in persons with exposure to pigs in the United States.
Abstract
Background Triple-reassortant swine influenza A (H1) viruses — containing genes from avian, human, and swine influenza viruses — emerged and became enzootic among pig herds in North America during the late 1990s. Methods We report the clinical features of the first 11 sporadic cases of infection of humans with triple-reassortant swine influenza A (H1) viruses reported to the Centers for Disease Control and Prevention, occurring from December 2005 through February 2009, until just before the current epidemic of swine-origin influenza A (H1N1) among humans. These data were obtained from routine national influenza surveillance reports and from joint case investigations by public and animal health agencies. Results The median age of the 11 patients was 10 years (range, 16 months to 48 years), and 4 had underlying health conditions. Nine of the patients had had exposure to pigs, five through direct contact and four through visits to a location where pigs were present but without contact. In another patient, hu...

Emergence of a novel swine-origin influenza A (H1N1) virus in humans.

TL;DR: A novel swine-origin influenza A virus was identified as the cause of outbreaks of febrile respiratory infection ranging from self-limited to severe illness and it is likely that the number of confirmed cases underestimates thenumber of cases that have occurred.

TL;DR: The lack of similarity between the 2009 A(H1N1) virus and its nearest relatives indicates that its gene segments have been circulating undetected for an extended period as mentioned in this paper.

Origins and evolutionary genomics of the 2009 swine-origin H1N1 influenza A epidemic.

TL;DR: It is shown that the new swine-origin influenza A (H1N1) virus emerged in Mexico and the United States was derived from several viruses circulating in swine, and that the initial transmission to humans occurred several months before recognition of the outbreak.

Cross-Reactive Antibody Responses to the 2009 Pandemic H1N1 Influenza Virus

TL;DR: Vaccination with recent seasonal nonadjuvanted or adjuvanted influenza vaccines induced little or no cross-reactive antibody response to 2009 H1N1 in any age group.

Prevention of rotavirus gastroenteritis among infants and children. Recommendations of the Advisory Committee on Immunization Practices (ACIP).

TL;DR: The Advisory Committee on Immunization Practices recommends routine vaccination of U.S. infants with 3 doses of this rotavirus vaccine administered orally at ages 2, 4, and 6 months.

Swine influenza A (H1N1) infection in two children - Southern California, March-April 2009.

TL;DR: Concern exists that this new strain of swine influenza A (H1N1) is substantially different from human flu viruses, that a large proportion of the population might be susceptible to infection, and that the seasonal influenza vaccine H 1N1 strain might not provide protection.
