I couldn't see examples of the eggs, but there are many fungal infections that look like eggs. The rest of the tree does appear to have sustained a fungal infection. This can happen in places where there is a lot of rain, and very little time to completely dry out in between.
Such areas will require a little foresight for prevention. Using DOLOMITIC lime and WETTABLE sulfur together will be a good preventative, as well as spot treatment.
These may best be purchased online.
If the problem still persists in a year, then harsh copper fungicides may be in order. Consult with all local laws regarding the use of such products before using them.
