Weak and struggling to breathe in the Intensive Care Unit of the Kenyatta University Teaching, Referral and Research Hospital, Dr Stephen Mogusu warned his colleagues to save themselves before it was too late.
He sent the WhatsApp message hours before he succumbed to the virus that has killed 1,531 Kenyans.
"My dear colleagues, let me take this opportunity to admonish you today to get your pay or get out while you can with your health or life intact," texted the late doctor.

The 28-year-old stationed at Machakos County succumbed to Covid-19 on Monday at a time when his family, together with Kenya Medical Practitioners, Pharmacists and Dentists Union (KMPDU), tried to raise money for his care and hospital bill.
The news of his death was reported by KMPDU which has called out the government to safeguard health workers who work in a risky environment for months.
