Does anyone on this site have any information (preferrably with a literature reference) on the use of the influenza virus as a model to study other viruses?

Does the seasonal flu shot prevent or diminish the ability for the person who got the shot from carrying and or transmitting the virus?

Hard to speculate on what happened. Unless there are animals around,
the droplets won’t contain animal viruses, which are most likely to
infect you. Plant viruses aren’t likely to make you sick – at least we
don’t think so. An environmental toxin in the droplet? Allergic
reaction perhaps?

So, can you help answer a question. I recently visited the island of Hawaii. I traveled to the more dap volcanic side of the island in the Valcano National park. It was rainy and misty and sub-tropical in some of the areas. While hiking along a trail I innadvertantly inhaled a single droplet of moisture. I almost instantly reacted negatively to it. Two days later I was laid out cold!. I have fought cancer before and I can tell you this little inhaled droplet was as bad as one of my bad treatment days with chemo. I do not believe that a virus is contracted necessarily from human droplets as there was no one on the trail anywhere around us. I will tell you I think something like this happened to me before with moist air. It is really scary! Any ideas>

If face masks are useless, then why do surgeons wear them when they perform surgery? Sure, nobody with any common sense believes they offer 100% protection, but even a little extra protection is better than none. Another thing that I find outstanding is that nobody seems to be mentioning the use of protective gloves. Handwashing may be fine, but doesn't prevent germs from getting on your hands and spread around. Sure, gloves don't prevent germs from being spread along surfaces once on the glove, but – without gloves, most people touch their faces, scratch an itch, or rub their eyes without thinking just as part of normal reaction. Gloves create a more conscious awareness of the contact we make with our faces. And of course, gloves prevent germs from getting on your hands in the first place, which helps with the problem of poor handwashing techniques, (and lack of soap and water or lack of disinfecting lotion), or times when constant handwashing would be needed when in contact with a sick person. As a mother, I have found that I dramatically decreased my own chances of getting sick every flu season by using gloves when my child is sick. And parents know how challenging it can be to manage the constant bodily fluids that fly in every direction from a sick kid. They are little disease factories. Ideally, a glove that contains disinfectant or such on it's outer surface would be very ideal. Hmmm… wonder if anyone makes anything like that?

Why does the CDC recommend against face masks when the science clearly shows they are exceedingly beneficial at stopping the transmission of flu-like disease?

Here's a study I found on the CDC's own site clearly demonstrating the efficacy of properly fitted N95 face masks during the SARS outbreak.

It is true that some of the assays are complex, and several are used.
The older method is to isolate the virus in cell culture by
inoculating a nasal swab specimen into cultured cells. Then a panel of
antibodies against the 16 known HA subtypes are used in a variety of
assays, such as neutralization assays, in which the capacity of the
antibody to block infection is determined. For example, if the virus
is an H1 virus, only antibodies against the H1 HA would block
infectivity. Other assays are also used. Other diagnostic methods
include direct fluorescent antibody testing, immunoassays, real-time
reverse transcription-PCR, sequencing, and multiplex RT-PCR. Viral
culture is the "gold standard" for typing and subtyping of influenza
viruses, but takes 3 to 7 days to culture the virus. In experienced
hands they are not complex, but they must be done properly to have
confidence in them. Lab personnel need to be trained in the methods
because clearly a great deal depends upon a reliable test.

I was reading that some countries do not have the techniques for testing if a virus is of the present H1N1 type.
Which exactly is the procedure for this test
and why it is so complex/expensive?
