My WCC and other counts are normally lower than yours, but I manage to keep well most of the time. I used to get lots of infections. A couple of natural easy things I've found helpful in avoiding infections (you may already be familiar with these):
1. Avoid foods containing cane sugar. Unheated honey is fine.
2. Take 5000 mg Echinacea and a product containing astragalus as soon as you feel a sore throat starting and continue until the soreness is gone.
3. Be fanatical about hand washing.
4. If you are prone to urinary tract infections, have cranberry capsules on hand and take them on the slightest hint.
5. Coconut oil is an antiviral. Read more on

6. Clean wounds/bites with hydrogen peroxide ASAP.
All the best!
