Nakuru County Teaching and Referral Hospital Medical Superintendent James Waweru confirmed that two people aged 37 and 41 died while they were receiving treatment at the facility.
One person was brought to the hospital morgue on Saturday morning.
Officials said it remains unclear where the illicit brew was sourced from as one of the deceased persons brought the liquor and shared it with his friends.
This is as they celebrated ahead of the festivities.
