recovered from or cured of late blight?

[tjg911]

of 11 plants 5 are dead. some are alive but have no fruits.

however, these plants are still alive, have some foliage with no signs of LB, have tomatoes without any LB lesions and have no LB on their vines :
1. sun gold lots of flowers and i'm picking a fair amount of tomatoes
2. prue between 2 plants in the same cage there are 5 tomatoes 1 is turning red
3. nicky crain has 3 tomatoes and i picked 1 today as it's 1/2 colored
4. aunt gertie's gold has 1 green tomato

isn't LB suposed to kill tomato plants in just a matter of days? how is it that 7 weeks after LB was found i have 5 plants that have healthy foliage and healthy fruits? all 11 plants had LB on their leaves and then the ripening fruits, there's no doubt of that. i did not use any fungicides. i did spray fish milk for a few weeks but gave up when it appeared all was lost, that was 2 weeks ago. i did not tear out any plants (except for reif's red heart 7/10 or 7/11 as it was the 1st infected plant) and i'm surprised to see these 4 doing so well!

did the dry weather and sun cure them of LB? that's impossible from what i have read.

did the fish milk give them a boost to survive?

did both work together?

i'd sure like to hear from you folks, why are these plants not only alive but apprear to have fully recovered!
