Swine flu: an old virus with a new face

ABSTRACT

This review is describing the current world status of the recently identified swine origin influenza virus A [H1N1] outbreak with special focus on Jordan. This recent outbreak originated in Mexico and spread to more than 40 countries including USA and has been caused by a novel swine origin influenza virus A [H1N1]. This virus is thought to be a result of a genetic reassortment process that took place in pigs. This disease affects mostly young people with symptoms that are similar to those of seasonal influenza. Sustained human-to-human transmission has been documented and the virus is so far resistant to both amantadine and rimantadine but susceptible to oseltamivir and zanamivir. The World Health Organization [WHO] has raised the level of influenza pandemic to phase 5 and future speculations seem to be uncertain. Laboratory diagnosis is confirmed using a swine virus real-time, reverse transcriptase PCR test. No cases have been confirmed in Jordan. Nevertheless, Jordanian health authorities have started a very serious cascade of actions based on a comprehensive preparedness plan and supported by the already available infrastructure, increasing stockpiles of medications and protective equipments, and strengthening infection control preparedness of health care facilities
