Covid19 is genuinely unpredictable. It will spare a country/region and then suddenly reappear in full rage. For almost a year it seemed that East & SE Asia had controlled it, but now Japan is witnessing spiralling numbers 1/n

If you are trying to correlate this spike to temperature/winter, note that same spike is happening in Malaysia that is near the equator and barely sees any seasonal variation. Indonesia is also seeing an acceleration 2/n

Meanwhile, Vietnam is going about life as if nothing happened. Please don't try to argue that this is due to Vietnamese self discipline. Try crossing a road in HCM and you will know what I mean (much crazier than Delhi).

We witnessed this in Europe as well. The virus initially spared Germany, and then it spread like wildfire across the country. Lesson: Past success if no guarantee of future performance. Vaccination is perhaps the only real solution. 4/n

Meanwhile, China has locked down two major cities in as many days: https://www.wionews.com/world/a-year-after-wuhan-outbreak-two-chinese-cities-placed-under-lockdown-355423
