Once all countries are allowed to come to Singapore after 26 OCT, local infection will surge because Singapore is small and crowded,infection will spread fast.

Nov and Dec infection number will be very high.
Death rate will be the highest.

I concur with your findings, come nov./dec. which is winter months in the upper hemisphere, the Covid-19 viruses tends to spread very fast....we may see a spike in number of infections, viruses coming from other countries, which may be carrying a mutated virus, like Delta Plus...
