Only transmissible by blood and the surfaces or objects contaminated with viruses, which are called fomites. The flu is distributed in seasonal epidemics which cause hundreds of thousands of deaths that will be millions of years in the pandemic. During the twentieth century there were five flu pandemics. Treatment is symptomatic and only in serious cases and only hospital is keeping constant, because the antiviral drugs have limited efficacy and not without toxicity.
Antibiotics are only useful if there is associated bacterial infection. The swine flu is an infectious disease caused by any virus belonging to the family Orthomyxoviridae, which is endemic in pig populations. Although the swine flu does not affect regular human population, there are sporadic cases of infections in humans. Generally, these cases occur in those working with poultry and pigs The swine flu infects people every year, and is often found in those who had contact with pigs in a job Symptoms in humans include: increased nasal discharge, cough, sore throat, high fever, malaise, loss of appetite, joint pain, vomiting, diarrhea and, in cases of bad outcome, disorientation, loss of consciousness and, occasionally, death.
