The Chinese economy was being trashed by SARS and especially by the travel restrictions. They desperately wanted those lifted, and consulted with the WHO in May, and even got them to visit one province Hebei. The WHO showed them exactly which numbers would be 'tracked' to determine their containment. Instantly, China started reporting 'perfect containment' in virtually EVERY province other than Beijing.
Many provinces which HAD been seeing their case counts double every six days, abruptly flat-lined with NO NEW CASES from May 10th, or May 14th, until now.
Here is just one example, Inner Mongolia... 
[abrupt change occurred May 10]
Inner Mongolia's TOTAL 'probable' case count
was doubling every 6 days, then abruptly flat-lined
A similar pattern was observable in Taiwan, where they obviously were reporting just their CRITICAL cases as 'probable' SARS. The death rate within this group was exceeding 90%. Meanwhile, they were also collecting hundreds, and then over 1000 'suspected' cases. [But the world pays no attention to 'suspected' cases and they knew that].
To this day, they still hold WAY back on the numbers they report as 'probable', and maintain a HUGE backlog of hospitalized 'suspected' cases. But something caused them to change gears about May 28th, and completely STOP reporting ANY DEATHS from this 'probable' group. Most likely it had to do with lobbying the WHO to remove their travel restrictions.
Anyway, the same familiar bogus curve appeared in Taiwan's death counts...
Their reported deaths HAD been doubling every six days, but then abruptly flat-lined.
A few days ago, a government watchdog group in Taiwan reported that the government has cremated 363 SARS patients, but Taiwan had only reported 81 having died. I extrapolated out conservativly if they really COULD have had 363 SARS deaths based on where the trend HAD been heading before it flatlined. I found that the numbers could easily have exceeded 363 dead, so the watchdog group sounds very believable.
Taiwan's SARS deaths were DOUBLING every SIX DAYS. I conservatively spotted them one extra days, and doubled their deaths every SEVEN days starting from where the curve turned 'truth-challenged'...
DATE__ - _REPORTED
May 01 - 3 deaths 3 deaths
May 06 - 10 deaths 10 deaths
May 12 - 20 deaths 20 deaths
May 18 - 40 deaths 40 deaths
. . .
May 10 - 81 deaths 356 deaths
May 11 - 81 deaths 393 deaths
May 12 - 81 deaths 434 deaths
May 13 - 81 deaths 480 deaths
We have even less ability to scrutinize mainland China's numbers, since it is illegal to phone, fax, or use the internet to communicate out in any way regarding SARS. Their numbers are even more likely to be fabricated than Taiwan's.
It is VERY unfortunate that the WHO LIFTED the travel restrictions to many Chinese regions including Inner Mongolia, Hebei, Shanxi, Guangdong, and Tianjin.
I can only conclude the WHO decision makers displayed either Hillary-like gullibility, OR, Bubba-like greed for Chinese currency.
Time will tell what happens, and it will be interesting to watch, but your headline would be more accurate if it read...
SARS will LOOK like it has gone to ZERO by month's end.
Keep up the good work on presenting professional looking charts, but please be careful what you conclude, because China and Taiwan's number are VERY much bogus.
