oralengineer advice sheets for what? There weren't any reported cases of this virus in October, let alone a test. Got a link for those screenshots? It would be good to see the context.
They were slow to announce pandemic. They dithered about and were wholly unconvincing with their initial briefings.

'Pandemic' isn't a thing, it's just a rhetorical word.
WHO declared a Public Health Emergency of International Concern on January 30 when, outside of China, there were 82 cases and no deaths. This is the highest level alert they can give. It's technical language for 'pandemic'.
On January 30 we had 0 confirmed cases and 0 deaths.
Some countries continued to whinge at them to say 'pandemic' and they resisted for a while. They said they were concerned that calling it a 'pandemic' would lead to countries giving up on containment measures like testing and isolating cases and tracing and quarantining contacts.
They gave in on March 11 because they were so concerned by the lack of action from some countries with rapidly escalating levels of infection. They used the word despite its lack of technical meaning in an attempt to get certain countries ('You know who you are') to take it seriously. Because apparently 'Public Health Emergency of International Concern' doesn't sound very serious 
By March 11 we had 456 confirmed cases and 9 deaths. We had just decided that all this testing and contact tracing was a bit too hard so we'd stop doing it. We'd just settle for 'flattening the curve and delaying the peak'. Same amount of death and serious illness, just more slowly.
March 12, Boris tells us 'many more families are going to lose loved ones before their time' and Vallance starts talking about herd immunity.

So WHO were right the first time. Declaring a 'pandemic' just led to our government giving up.
Kerala had the exact same amount of time and warning as we did. They had their first case 4 days before us but they put systems in place so they were ready for it and they have relentlessly stayed on top of it.
We had plenty of time and plenty of warning, we just fucked it up. Jenny Harries said we didn't need to follow WHO advice because it was for low and middle income countries.
