<has begun/begins> to take effect

[Tait-ka]

Krait bites tend to leave little local swelling or bruising, which is part of what makes them so dangerous: people often do not realize they have been bitten until the venom has begun to take effect.

Can I also say "...the venom begins to take effect"? What's the difference in meaning between the original and this one?

There's no difference in meaning.
