And when we lose, we can lose quite badly. From that paper’s introduction:

“We present data that ΔH69/ΔV70 increases Spike-mediated infectivity by approximately two fold”

Δ in this case means “deletion”; it is not part of the name of that part of the sequence. The deletions double the infectivity.
