Probably a significant proportion of the Mexican population of US because they have not evolved enough to protect themselves from it.

Fingers crossed...... n'ah I'm only kiddin, I love my American cousins!

no

Probably not However miracles do happen sometimes

No. We're paranoid enough and in good general health. If it gets into a nursing home it may kill some people,, but the American health system is quick to respond to outbreaks like this.

Its mortality rate is somewhere between six and seven percent.

No. We are already alerted, and know how to take the proper precautions. Diseases are more likely to be dangerous when we DON'T know they exist, and when we are not looking out for them.

Maybe the elderly might have an issue, but I wouldn't let it scare you too much.

I think we'll be fine.

i doubt it, and its been more lethal in people 25-50 then any other age range, but unlike mexico america is very advanced in healthcare, they are already sending out vaccines for it just in case

Swine influenza, or swine flu, is a highly contagious acute respiratory disease of pigs, caused by one of several swine influenza A viruses. Morbidity tends to be high and mortality low (1-4 per cent). The virus is spread among pigs by aerosols, direct and indirect contact, and asymptomatic carrier pigs. Outbreaks in pigs occur year round, with an increased incidence in the autumn and winter in temperate zones. Many countries routinely vaccinate swine populations against swine influenza. Swine influenza viruses are most commonly of the H1N1 subtype, but other subtypes are also circulating in pigs (eg, H1N2, H3N1, H3N2). Pigs can also be infected with avian influenza viruses and human seasonal influenza viruses as well as swine influenza viruses. The H3N2 swine virus was thought to have been originally introduced into pigs by humans. Sometimes pigs can be infected with more than one virus type at a time, which can allow the genes from these viruses to mix. This can result in an influenza virus containing genes from a number of sources, called a "reassortant" virus. Although swine influenza viruses are normally species specific and infect only pigs, they do sometimes cross the species barrier to cause disease in humans. What are the implications for human health? Outbreaks and sporadic human infection with swine influenza have occasionally been reported. Generally clinical symptoms are similar to seasonal influenza but reported clinical presentation ranges broadly from asymptomatic infection to severe pneumonia resulting in death. Since typical clinical presentation of swine influenza infection in humans resembles seasonal influenza and other acute upper respiratory tract infections, most of the cases have been detected by chance through seasonal influenza surveillance. Mild or asymptomatic cases may have escaped from recognition; therefore the true extent of this disease among humans is unknown. It is likely that most of people, especially those who do not have regular contact with pigs, do not have immunity to swine influenza viruses that can prevent the virus infection. If a swine virus establishes efficient human-to human transmission, it can cause an influenza pandemic. The impact of a pandemic caused by such a virus is difficult to predict: it depends on virulence of the virus, existing immunity among people, cross protection by antibodies acquired from seasonal influenza infection and host factors. Most of the previously reported swine influenza cases recovered fully from the disease without requiring medical attention and without antiviral medicines. Some influenza viruses develop resistance to the antiviral medicines, limiting the effectiveness of chemoprophylaxis and treatment. The viruses obtained from the recent human cases with swine influenza in the United States were sensitive to oselatmivir and zanamivir but resistant to amantadine and remantadine. Information is insufficient to make recommendation on the use of the antivirals in prevention and treatment of swine influenza virus infection. Clinicians have to make decisions based on the clinical and epidemiological assessment and harms and benefit of the prophylaxis/treatment of the patient2. For the ongoing outbreak of the swine influenza infection in the United States and Mexico, the national and the local authorities are recommending to use oseltamivir or zanamivir for treatment and prevention of the disease based on the viruss susceptibility profile.

I don't think it will.
