Many infections - a sign?

I have been struggling for some time with various symptoms such as chronic fatigue, brain fog and a few others that are very probably CFS-related. Interestingly, I have been diagnosed with an increased number of bacterial infections since then, including reactivated EBV, HSV1/2, HHV6 and VZV (I still need to clarify whether this is really the case or whether the correct blood values have been determined, but it seems so). I also had a genital swab done as I also have severe itching with fluid discharge and it turned out to be a “massive infestation with Staphylococcus aureus and noted E.coli”. I have also had genital warts for some time (HPV?).

I don't want to exaggerate but I would like to ask you directly, it is somehow conspicuous that I have/get so many bacterial infections and seem to be susceptible to them? Can we still talk about coincidences or “it can happen to anyone?” or does this seem to be serious and the root of my problem?

It seems to indicate a weak immune system, but I have to say that I haven't been really ill for 6-7 years. As mentioned, I have the problems with chronic fatigue, brainfog and various others...so yes, this is of course catastrophic, but I'm not really “ill”, i.e. with a fever, cold etc. and haven't been for ages. How does that fit together?

Where should I start and which examinations should I continue to carry out?

thanks for the help!
