Unlikely -- it lacks some of the virulence factors that the 1918 flu had, our medical system is better, and we have a generally healthier population.

Nope, just our collective immune systems.
Alan McDougall;60263 wrote:I know there are a few antiviral drugs, but could the AIDS drugs be used for the general population if this outbreak became a global pandemic?
There are a lot of antivirals that are active against HIV, and a few of them have activity against the Hepatitis B virus, but they have no activity against influenza. There are only two classes of drugs active against influenza, the neuraminidase inhibitors (oseltamavir (Tamiflu) and zanamivir (Relenza)), and the adamantanes (to which this H1N1 virus is resistant).

Could millions die if this got out of control?
Modern medical interventions could make an enormous difference. Many if not most people who die from flu die because of a superimposed bacterial pneumonia. We did not have systemic antibiotics in 1918. As to whether millions could die, millions
already die every year from the normal seasonal circulating flu strains -- as many as 30,000 every year in the USA alone.

What would the effect be on sports events with crowds of spectators
A single person in a crowd of 80,000 people at a huge stadium might infect a handful of people around him. They would not be able to spread it to others until after a minimum incubation period (days). It wouldn't spread like wildfire through that crowd unless you had a lot of contagious people from the start, and if you get 3-4 secondary cases for every primary case then even 100 contagious people could lead to a very large community spread. As for airplanes, there is definitely transmission of respiratory viruses on planes, but it's pretty uncommon for things other than tuberculosis to spread to distant parts of the airplane. Air traffic just depends on how draconian the national public health folks want to be. It makes sense for Mexico to restrict flights, because they have a comparatively high number of cases, but it doesn't make sense for other nations to do so.

This epidemic will probably have burned out by the time a vaccine is available 4-6 months from now.
Alan McDougall;60263 wrote:The virus could mutate and become weak or it could mutate into different deadly viruses for which humans have no protection?
It already is one for which we have no protection. The issue is whether it can genetically recombine with other human influenza viruses that are either more virulent or more transmissible.

It has nothing to do with pork.
Alan McDougall;60263 wrote:I think the masks presently used by people are useless against a tiny virus, it would have no problem getting through into the body
They're not useless at all -- the viruses are within droplets of liquid that cannot penetrate the mask. The problem is that the droplets only travel 3-5 feet, so you're not cutting out very much exposure by wearing masks, and you're not protecting your eyes. Keeping your hands clean is the best measure.
Tuberculosis is one example where the respiratory droplets are much smaller and stay aerosolized for longer, so you do need special masks (we have to be fit tested for these once a year).
Alan McDougall;60263 wrote:This outbreak could advance and spread in biblical proportions or we might wake up and hear the whole thing was now under control
Would the authorities hold back the truth from the population if they knew for sure this was an outbreak of deadly biblical apocalyptic pandemic proportions?
The "authorities" wouldn't have control over that information. If hospitals suddenly begin filling up with sick flu patients, and people start dying at unexpectedly high rates, and intensive care units need to close because they're full, then we'll know. There are news teams crowding around my hospital and probably every other, and they get their news from hospital spokespeople, not "authorities".
Alan McDougall;60263 wrote:If the truth was the worst possible will the authorities tell us or just keep quite because telling us will not alter the outcome?
Public health epidemiologists have been modeling flu control scenarios for decades. Keeping it a secret does no one any good. The key to a major epidemic is to close schools, public transit, i.e. things where tons of people come into close contact, and keep a required minimum number of essential services operating.
