Yemen (on April 29th of this year) had an outbreak of 5 COVID cases, and an immediate 2-week lockdown was imposed. Though that number seems quite small, the health system was quickly overrun. This is because Yemen's health department has been "devastated by war," and though Saudi Arabia declared a unilateral cease-fire on April 9th, airstrikes by a Saudi-led coalition increased 30% from April 22nd - 29th. Even pre-COVID, Yemen had a cholera outbreak in January, quickly exacerbate by torrential rains and putting 5 million children under the age of 5 at risk.
