This paper gives estimates of Wuhan-area cases ranging from 7600 to 43600 for January 26.
A doubling time of 6 days was estimated for the pre-lockdown phase of the Wuhan epidemic.  That gives a factor of 2.5 increase in cases between Jan. 18 and 26.
Unfortunately the newer estimated case numbers are somewhat higher than 2.5 times as many; probably the older number were too low.
Note the estimated rate of increase is much LOWER than one would naively get from looking at the officially confirmed case numbers. Confirmed cases have been more than doubling every two days. This growth rate of confirmed cases is really the rate of increase of China's capability of carrying out confirmation labwork.
There exported case research shows there is still a huge backlog of unconfirmed cases to be identified in the Wuhan area.
 See "Report 2" at https://www.imperial.ac.uk/mrc-global-infectious-disease-ana...
The median estimate of the size of the outbreak by Imai et al as of Jan 18 is 4,000; the new median estimate by Chinazzi et al as of Jan 26 is 21,300 (assuming a catchment population of 20M, their middle case). If both median estimates happen to be spot-on, the size of the outbreak would have grown by a factor of 5.3 between those two dates.
Probably the newer estimate of total cases is ALSO biased too low. The reason for underestimate is they are assuming international surveillance found all exported cases. The paper describes this shortcoming:
The estimates contained in this report have been constantly growing with respect to older
versions compiled with the data available at previous dates. This is because the number of
detected cases at International locations and a travel history from Wuhan city has nearly
tripled in the last week. It is worth stressing that this is not implying that the epidemic is
growing at the same rate. The estimated size of the outbreak refers to all cases occurred in
the area since the beginning of the outbreak, and notification and detection delays may play
an important role that, at the moment, do not allow the evaluation of the epidemic growth
That being said, it’s also entirely likely that even the Chinese known exactly how many cases there are:
1. Cases aren’t detected unless you feel sick enough to go to the doctor
2. Even if you go to the doctor, the symptoms have to be strong enough for the doctor to order the specific test. This is a bigger factor in the early days. After the alert is given they likely start testing everyone, at least until the outbreak is large enough that it becomes moot
3. The big question (that I haven’t seen answered yet) if how long the assymptomatic incubation period is. In other words how long can you spread it before realizing you’re sick.
In the end, the factor that will determine how large of a global outbreak were actually dealing with is now transmissible it is from person to person. From what I’ve seen all foreign (outside China) cases have been traced back to China, meaning that person to person transmission isn’t a large factor yet. If/when it does become a factor that’s when the real containment “game” starts...
- recovery time? E.g. How long for the virus to run its course for those that recover.
- total number of recovered people
- why no babies / kids appear to show up on fatality statistics at least?
- how useful are those surgical masks for preventing getting sick / infecting others?
- what kind of masks actually provide protection against virus?
After SARS the CDC published updated guidance on masks in relation to Influenza in general. TL;DR is use regular paper masks for general population, hospital staff, and patients. N95 masks for staff doing intake and direct treatment. This addresses the primary problem with N95 masks: hospitals running out.
The "N95" rating means it filters 95% of particles 3 microns or larger. Research showed only Influenza particles 4 microns or larger carried enough RNA to replicate successfully.

The leading theory seems to be that eye protection is necessary as well.
Hopefully it gets seen by enough people who will put the tips into practice and slow down the spread of the virus.
Preventing the spread basically comes down to avoiding people. I'm not sure that is great advice. The rest of this site is just things people should be doing anyway like washing their hands.

You made a guide homepage in the post I answerded to, which repeatedly mentions "if you have these symptoms". But the symptoms are not mentioned in the guide.
I think for a proper guide you should absolutely list the symptoms of corona virus at the introduction.
I searched in search engines. As far as I could find the corona virus symptoms are similar to pneumonia. The main symptoms are fever, cough and pain in the lungs.
This is not similar to flu symptoms which do not necessarily spread to the lungs.
there are a lot more cases which aren't on the official figures.
Furthermore, I think China should get some very severe sanctions from the international community for covering up the existence and how wide-spread the virus was.
....Under-report to avoid embarrassment.
...."We only gave them the propaganda number, so the aid they sent never could have helped."
....Then wait 'til the international community calls your bluff.
....which requires that the effects spread internationally before anyone uncensored starts getting solid data.
....by which time it's too late to contain.
