I think there are lots of reasons to be positive, actually, so no I don't see there being a very significant second wave or lockdown.
We are actually doing pretty well at contact tracing right now. More resources are going into that so it will be better still by winter. It does make a difference, as parts of Spain have discovered. It is being taken seriously here.
People are better at washing their hands and the evidence is that was making a pretty big difference to spread before lockdown. It's really the number 1 thing people can do beyond staying in if they get symptoms.
The government is working to increase testing capacity to 500,00 a day by autumn so we can catch more cases and prevent spread.
People can get tested and get results far more rapidly if they feel ill - at the start of the pandemic that wasn't the case at all. The quicker results come through, the quicker you can get people to self-isolate and that limits how many people get infected overall.
People are moving to wearing face masks and I think will wear them more in the winter as cases rise - most people don't want to get sick. It's different now because the weather is good and so much going on is happening outside.
Treatments are better as is knowledge of how to keep the most vulnerable people alive - there is clear evidence fewer people who get seriously ill with this are dying than at the start of the pandemic by quite a significant number. That is only going to improve as the months go by as other treatments are tested.
The vaccine trials are going really well.
Screens are up in various workplaces, reducing spread even if only by a little.
We have (hopefully!) learnt some very painful lessons about sending people back to care homes from hospitals. Huge mistakes were made but if you can change your policies around how people are sent back to homes (eg after 2 negatives tests) you can keep care homes safer and there will be fewer deaths. We know the vast majority of people who die of this virus are elderly and have multiple health issues so focusing our attention on protecting and shielding these people will have an impact on death rates
There is going to be a huge drive to do more flu vaccinations which will help reduce overall deaths.
We have the ability to do targeted local lockdowns and using Leicester as an example has shown that works to contain outbreaks, hard as those small lockdowns are.
There is lots of research saying some/many have innate immunity which might well make a difference to how the virus spreads a second time if things do hot up. More information is needed about that though.
I am still feeling cautious and obviously we need the government not to botch this and people to take preventing the virus from spreading seriously but there are so many reasons to have hope. We are in a completely different situation to March. I do think there will be outbreaks and deaths but we get flu deaths each winter anyway. 50,000 in 2017, in fact - which, by the way, few people even noticed if they weren't directly affected.
