Ann Arunga, a 77-year-old retired clinical officer who was admitted at Kakamega Referral hospital’s Intensive Care Unit (ICU), surviving on life support. [Courtesy] My mother Ann Arunga battled Covid-19 in the ICU ward of the Kakamega Referral Hospital, where she had worked as a clinical officer before retiring. At 77 and hypertensive, she precariously hung onto life. Her oxygen levels that were supposed to be over 90 were dipping dangerously to between 40 and 50. Aware of the pandemic’s havoc, I bought an oximeter (a medical device that checks oxygen levels), eucalyptus for inhaling through a steam bath, and vitamin C and zinc tablets to boost immunity.
