Wharfie, I've spent some time on the West Coast of the USA and while there is fog in summer, it's not quite the same as winter dew point cold conditions.
For a start, it lasts too short a time. Around San Diego, the fog is gone by midday. Then it's sunny and warm again. The bugs can't get established. Also, the dew point is not at ground level. It's a bit higher up. At ground level, the air is clear. If you smear a drop of water on a surface, it soon dries.
There also needs to be a critical mass of virus in humans, like there needs to be sufficient uranium to get a chain reaction going. Even if there are 100 people with a flu, the propagation rate is too slow for the dew point conditions to get it going in a big way.
These things are fairly finely balanced.
I am seriously considering where to move to. It's not just dew point. In Auckland, all the water means plants go berserk, with fungi sprays, pollens, house mites producing allergens by the ton. Maybe I should buy a few million hectares of Australia and prepare for the ice age. I could sell it to a billion people looking for warmth when the ice age returns. In the meantime, it would be hot and dry. Great!
