If the nCoV is infectious while in an asymptomatic condition which is at least a 50/50 proposition, and anecdotally probable, then screening by temp probes remotely is lip gloss. The only manners to control this is by isolation, at least long enough to ensure that there is no chance of transmission to the protected population, or to develop immunity through achieving promptly a vaccine, or, to focus on personal protection and follow up therapeutic treatment of symptoms as they develop.
Of these options, we have lost the opportunity to stop the spread. The current figures ex JHU appear to be well underreporting total cases, consider that the likely spread is around an order of magnitude higher than reported to date. (If the amount of Wuhan-ians (Wuhan-ettes?) that are getting onto planes and then showing symptoms around the world, some 60 so far all happened to be at the same market/restaurant/beerfest/square dance/legionnaires convention, then their numbers make sense, otherwise, the spread was much higher in Wuhan at the start of the program, or people who fly happen to be more susceptible to the virus. Whatever. Or the reservoir numbers were already huge.
Good news so far is that of those that travelled overseas, there appears to be a very low mortality rate, and that suggests that discounting attenuation, that reasonable medical symptomatic treatment may be effective. That is just hinted at and is a best hope case.
In our region, shelves have already emptied of all N95 masks and hand sanitiser. That is a good thing, it at least suggests that at least the public are taking the issue seriously even if the govt's haven't. However, the use of masks even in the medical profession is just dismal, look at any images of people taking the time to put on a mask, and then lowering under their nose, while standing around other people. Watch if they take any care to avoid touching the mask, or taking any care with the mask being contaminated... Disposal of masks is also reminiscent of the condoms around Rome. So.... you get out of the bad place (supermarket etc...) and then just outside of the car you drop the pesky mask on the ground. How? Were the hands in gloves? Were the hands cleaned after being contaminated by removing the masks before touching the car door handle? (thanks for leaving a potential viral load in the carpark BTW, well done sir/ma'am). Personal protection is not that hard, but it takes deliberate steps to be effective. If the individual is not deliberate, then there is little point in bothering, in which case, take solace in the current anecdotal effectiveness of therapy at least outside of China. The images of dead bodies in the hallways of the local hospital suggest that the glastnost of the Chinese govt is open only to an extent.
Time for a holiday, at home, away from all others, and away from schools.
