Emergence and pandemic potential of swine-origin H1N1 influenza virus. Surveillance of European domestic pig populations identifies an emerging reservoir of potentially zoonotic swine influenza A viruses. This is one of the ways CDC assesses how closely related the circulating influenza viruses are to the viruses the seasonal flu vaccine was formulated to protect against.

Many other data, including antigenic characterization findings and human serology data , shape the vaccine selection decisions. One influenza sample contains many influenza virus particles that were grown in a test tube and that often have small genetic differences in comparison to one another among the whole population of sibling viruses. Due to the constantly changing nature of influenza viruses, every sample collected from a patient contains many influenza virus particles that have small genetic differences in comparison to one another.

Sanger sequencing identifies the predominant genetic sequence among the many influenza viruses found in a virus sample. This means small variations in the population of viruses present in a sample are not reflected in the final result. Newer technologies such as Next Generation Sequencing, described below are better suited for detecting small variations in the virus genes and offer advantages for whole genome sequencing. Therefore, NGS reveals the genetic variations among many different influenza virus particles in a single sample and can increase the speed and accuracy of sequencing each of the protein coding regions of the virus.

This level of detail can directly benefit public health decision-making in important ways, but data must be carefully interpreted by highly trained experts in the context of other available information.

RefSeq proteins. Sometimes people may become infected by touching contaminated objects or surfaces with flu viruses on them and then touching their eyes, nose, or mouth. There is no vaccine available right now to protect against the novel influenza A H1N1. There are everyday actions, however, that can help prevent the spread of germs that cause respiratory illnesses like H1N1 influenza.

Take these everyday steps to protect your health and avoid spreading the flu:.
