How a Virus Spreads Through an Airplane Cabin (gizmodo.com) 76
An anonymous reader shares a report: Traveling by plane greatly increases our chances of getting sick, or so many of us are wont to believe. To be fair, it's not uncommon to come down with a nasty illness after we return from a vacation or business trip. But is flying the culprit? The latest research suggests the answer is no -- but much of it depends on where we sit. New research published today in Proceedings of the National Academy of Sciences suggests that airline passengers infected with influenza -- a disease that spreads through the air -- aren't likely to infect other passengers who sit more than two seats to the left or right, or more than two seats in front or back. In other words, your chances of contracting the flu from an infected passenger are slim -- unless you're sitting within about three feet (one meter) of them. Given that three billion of us fly annually, combined with the popular conception that we often contract diseases inflight, it's surprising to learn that very few studies have looked into this issue in detail.
And about the contact version of the flu? (Score:3)
So how long does the flu virus sit on a surface?
Every time I see someone hacking up a lung on a plane I wonder how big a radius has that one person infected.
Then I think about how long the duration of the virus on a surface is.
Then I think of my inadvertent hand contact with such surfaces and the innocent brushing of my eyes or handling of something I might stuff in my mouth along with he virus.
I just don't buy what they are selling and I got my masters in public health with an emphasis in Tropical Disease.
Maybe diseases and their spread has changed somehow since I went to school?

In China they use IR cameras at the security gate. If you are running a fever, or hacking and coughing, you can't board the plane. The rationale is to keep disease in one province from spreading to the rest of the country, but it should also reduce in-flight infections.

Bird flu amongst other diseases I would think. With people packed in as they are in China, it seems like the spread of things could be a bit easier and quicker.
An old epidemiology professor reminded me that any single study is not often correct. Once their are 20 studies that back it up one may be on to something.
But alas, our anti-science society seems to latch on to every new study as if it is absolutely how things are rather than a study which points in a direction there needs to be more study.

The IR cameras are actually to detect androids/reptilians hiding among the populace.

You can always bring a respirator with a full face goggle, Heisenberg style. If you wear this during the flight, you're protected from airborne spit particles that are ejected when a neighbor sneezes AND you're protected from germs on surfaces (because you have to touch the surface with your hand and then touch your mouth/nose/eyes with your hand to get infected, and you can't touch your face if you have the respirator on).
After you get off the plane, take off the respirator first *then* thoroughly wash you

Kissing a healthy person who is not infected with a communicable disease = harmless. Kissing an infected person = you will be infected.

Go look up how little norovirus it takes to make a healthy person into a sick person. Did you know that the effectiveness of your immune system may vary.

You live in the middle of Silicon Valley where there is an epidemic of hepatitis via surface contamination. (Hep can survive on surfaces for weeks)
There are also regular norovirus outbreaks.
Both of these diseases can kill you and I'd hate to be the motherfucker who catches the both at the same time because his sleeve scraped some surface that some homeless supercarrier sat on to dump a load of bloody diarrhea.

How do epidemics on those vessels differ from airplanes? Seems it would be even less likely to occur given the fresh air and far less cramped accommodations, yet haven't several occurred in the past few years?
Very few flights last more than 12 hours, but many cruises last for days. Cruises provide fresh air, true, but you have more time together.
Re: (Score:2)
Cruise ships have much greater mobility of passengers on board, plenty of hand contact surfaces like stair railings and elevator buttons, common buffet tables and eating areas, gambling equipment, theater seats, hours spent standing in line, milling crowds, confined passageways, and a typical exposure window of 6-10 days.
I spent most of my one and only cruise (Alaska / Inside Passage from Seattle) on deck.

They also have more or less fresh made food. So if one of the food stuff is infected it spreads easy to the passengers and crew.

I had a flight some years ago where someone threw up just as the doors were being closed... the flight crew refused to re-open them due to some regulations or something... the flight had to continue on with the smell of vomit circulating the cabin for 5 hours. It is important to note that we were not all seated together, with 8-10 rows of separation on the flight. 24 hours after landing my entire family got full blown GI distress... and 24 hours after that, nearly every person we had interacted wi

I'm not sure if the AC can filter virus, I doubt it however.
For certain the AC causes "wind" inside of the fuselage and can so spread a simple sneeze much farer then just the next seats.

Yeah, but we are talking about the AC in an airplane. I google later a bit, perhaps they indeed have virus proof filters, too. After all it would make sense. But perhaps it is to costly or to heavy.

Unless you are elderly or immune compromised. Then they can kill you. If you are in one of those groups and you are lucky the people around you will be vaccinated and practice good hygiene. Even if young healthy people don't care that much about catching the flu themselves, maybe they don't want to accidentally kill their own parents/grandparents?

I always see the sneezers sniveling and rubbing their running noses, then walk to the toilet and steadying themselves by touching every seat top on the way, the very same spots all the other passengers touch as well on their way to the toilets.
