    FFP2 respirator only in situations where aerosol generation could occur. like if someone coughs?
    I'm happy for someone to correct me, but my understanding is an "aerosol generation" procedure as per the HSE would be something much more intensive than a mere cough, e.g. intubating someone.

    There was an incident early in the outbreak (in Italy I believe) where a surgical team became infected as they were operating on a patient who they didn't realise had Covid at the time.

    Would putting aerosolised anti-bacterial air freshener in the air conditioning systems of buses and trains work?

    A simple one for all buses would be leave all the windows open (perhaps even in winter).

    You would imagine that would reduce the risk considerably - the virus doesn't seem to like fresh circulating air.

    On public transport we need to open windows and ventilate. I don't care if you're cold, wearing an extra jumper is less hassle than being in ICU with airborne pneumonia.
    The only way to open windows on a number of Irish Rail trains is with a sledge hammer...

    Though putting in new modified windows would be an interesting option. It would make for a noisier journey for passengers but they might feel a lot safer with half a gale coming through.

    How is that dramatic?

    Sitting in a closed environment for an extended period of time just increases the overall exposure... And that's what being on a plane will do. Timing March 8th or June 15 doesn't make a difference when you have one person asymptomatic or presymtomatic on a plane.

    So would travelling on a bus for a couple of hours too.

    I think those trains have air conditioning. If they have HEPA filters as part of their air handling, it is probably OK, but I doubt they do.

    I've read of a few places with air-conditioned public transport retrofitting opening windows.

    Uncomfortable, but these are not normal times. It'd be interesting to get proper science done on this - there's no perfect answer to eliminate risk, but would one window per carriage be sufficient or does there need to be strong airflow etc. Essentially you're trying to replicate the risk that exists in the outdoors, where even a light breeze seems to make a big difference in dispersing the virus.

    Well they're hardly going to be able to leave them on when eating or drinking.

    Airline filtration systems are hosptial operating theatre standard, the risk isn't as high as you might think.

    Looking forward to getting back to traveling.

    Fair point so but the risk of contamination occurring is non zero in both an airplane and a hospital operating theatre. Compared to most other situations proximity plays a big role. (2m rule for that reason)

    The aptly titled "germs on a plane" paper explains more. It also references the "hit" movie snakes on a plane.

    https://academic.oup.com/jid/article/195/5/621/841980
    During the SARS outbreak, investigations were conducted among passengers who traveled on 40 flights with patients on board who had symptomatic SARS. Transmission is thought to have occurred on board 5 of 40 flights. On 4 flights, a small number of suspected infections occurred among persons seated within a few rows of the index patient, consistent with spread by large droplets. However, on 1 flight from Hong Kong to Beijing, 22 of 120 passengers and crew were thought to have become infected, which suggests airborne spread over a considerable distance [3]. Many commercial aircraft use vertical airflow and high-efficiency particulate air (HEPA) filters that should limit exposure to small airborne particles. However, there are no regulations requiring HEPA filters or for testing of the function of filters [10].

    Here's more info. I'd be of the opinion give the canaries a miss this year. We all have free. will though so we all should decide our own level of risk.

    https://www.sciencedaily.com/releases/2020/03/200330152126.htm
    "It's generally believed that infection spread in planes happens two rows in front and back of the index patient," he said. "During the SARS outbreak in 2002, on the few flights with infection spread, this was mostly true. However, a single outbreak accounted for more than half the cases, and half of the infected were seated farther than two rows away on that flight. One might be tempted to look at this outbreak as an outlier. But the 'outlier' had the most impact, and so people farther than two rows away accounted for a significant number of people infected with SARS on flights."

    Currently, with regard to COVID-19, the typical infected person is believed to sicken 2.5 others. However, there have been communities were a single 'super-spreader' infected a large number of people and played the driving role in an outbreak. The impact of such extreme events, and the difficulty in modeling them accurately, makes prediction difficult, according to Srinivasan.

    Maybe on the InterCity trains but not on some of the DART trains.

    Far fewer cases circulating in Europe at the moment though. If this was early March, I would agree with you, but the risk at the moment and into the summer must be extremely low.

    Anyone that doesn't feel like planes are safe can stay at home, simple.

    I won't be one of them

    You do know that Covid-19 is a virus and not bacterial?

    That's the current status now. The fact that a virus has been scientifically proven to spread in the close confines of a plane may be an inconvenience to some but it could cause the death of countless people when you factor in 2nd and 3rd order subsequent spread as had happened in US.

    No matter when we "open up", resume flights etc. This can happen. While I believe in life, liberty and the pursuit of happiness I don't agree with unrestricted travel/ no quarantine when the world is in the midst of a global pandemic.

    Would be great if planes could be regulated to be safe. O'Leary et al have made it clear they don't care about the quarantine / social distancing etc in the context of this pandemic and are legally challenging it.

    0 deaths in the North for the second day in a row and 6th time in last 9 days.

    Are they following the UK method of reporting only deaths of confirmed cases in a hospital setting or reporting probable deaths as we are?

    I wish all the air vents were opened at all times on the Bus Eireann country buses (the ones without windows). Every morning, I notice that many are closed.

    apologies to clarify, .0051 or indeed 0.5%, jesus that's still very low FFS.
    I 100% agree lockdown was brilliant in how we tackled it, I still don't see the figure going near what others say, algorithm or no algorithm.
    .

    Well it’s simple maths. If the Ro value is between 3-4 then it’s easy to see how quickly and entire population is affected.

    No different to the old maths problem of whether you want €1m into your hand or a penny doubled everyday for a month.

    it’s not clear what your point is. Are you saying that we shouldn’t have locked down because we were successful after the fact. it’s very clear in Bergamo and in New York what can and did happened without a lockdown.

    Yeah the risk is probably lower. I'd be concerned around the airlines and how flight routing happens. You could be getting a flight to somewhere in Spain and think it should be grand.

    What you might not know and could occur is that the plane you are on was on a different route earlier in the morning and someone who is a worker in a meat factory or a nurse who comes into contact with Covid patients is actually who had Covid (presymptomatic) sat in the same seat you now find yourself sitting in.

    Ryanair have stated they won't be cleaning in-between turn arounds only at end of day.

    Given the number of patients still in hospitals in UK the risk of something like that is low but significant enough for me to be unlucky.

    Other people would feel different and I respect that.

    That's a personal point of view but on the aggregate / societal point of view. The number of bums in seats and the frequency of flights means that the likelihood of that scenario is in fact quite high and could kick off a second wave.

    Spain is dependent on tourism to live. I'm not therefore while I respect their decision to reopen (out of necessity) I won't be sunnying myself on the costa any time soon.

    It's amazing the way only Iranian airlines are capable of spreading the virus. Iran bad, Ryanair good? BBC investigated. Watch the report and replace Mahan with Ryan. And Middle East with Europe.
    Coronavirus by Air: The spread of Covid-19 in the Middle East
    An investigation by BBC News Arabic has analysed flight tracking data and open source footage which shows how Iran's largest airline - Mahan Air - continued to fly while government flight bans were in place, and contributed to the spread of Covid-19 in the Middle East.
    Mahan Air ran hundreds of flights to and from Iran, Iraq, the United Arab Emirates and Syria between late January and the end of March. All these countries gave Mahan Air permission to land. And they did so while their own bans on routine flights from Iran were in place.

    It should be noted though that people weren't contracting the virus on board the actual plane. They were already infected before the flight - which is a different issue (the question of whether borders should be open or not).

    No , I'm not taking away from that at all. I think we've done a great job but at less than 1% of the population being diagnosed positive and 98% of tests negative in the last 2 weeks, I believe it's time to get on with life in all seriousness.

    I don't care if every self professed couch microbiologist/virologist/epidemiologist thinks, we simply cannot wait til ZERO cases country wide like new Zealand. I think we have now been conditioned to habitually wash hands, stand away and be cautious, which is great.
    That's all I was saying, also less than half of one percent is the UK infection number too, bad as they were.

    And you know this how? That's a bit of an absolutist statement given the number of flights and people on them and the fact that studies of SARS have shown people did contract while on flight with infected person. I'd bet at least one did but like you.

    I DON'T KNOW.

    IMO once I am sat on a plane my mask and hand sanitizer I would be happy enough.

    Its the getting to the airport, getting through the airport, boarding the airplane, waiting for the pane to get turned on... Then repeat at the other end that concerns me.

    I watched a documentary a few weeks ago and it was filmed before Covid
    A team swabbed every surface in a large airport . The surfaces were covered in germs , viruses and bacteria . The worst areas were the handrails on escalators, the metal seats in the gate waiting area . The handrails on the rolling walkways , the check in machines . Before you ever get on a plane your hands are covered in germs
