Claim summary · not a verbatim quotation
There are currently 110 BSL-4 laboratories worldwide.
The finding
What the evidence shows
This overstates the confirmed count. A recent academic paper that tried to map high containment labs worldwide identified at least 69 BSL-4 labs globally, well short of 110, though the field keeps growing fast and a fully complete count is hard to pin down since some countries don't disclose their facilities.
