Welcome to HCM.
Your physician is exactly right in his prediction.
As long as your Viral load
is in undetectable level there is nothing to worry. The reduction in CD4 count and ratio may be due to recent illness, you had, say flu
. Repeat the count after 3 months you will be seeing everything is fine.
Sometimes if your immune system might have not been recovered well if you are an older individual or ART started in very late stage, it may be like this.
Wish you a speedy recovery.
