The improvement of functional handwashing facilities during COVID-19: the perspective of Tanzania.

Fighting against coronavirus disease-2019 (COVID-19) goes hand in hand with the provision of proper water, sanitation, and hygiene (WASH) services. In this case, proper handwashing with soap and water plays a major role in the prevention of COVID-19, since it helps to deactivate and remove virus particles from the hands. This letter points out the drivers for the improvement of functional handwashing facilities during the COVID-19 pandemic in Tanzania, whereby three out of every 20 non-functional handwashing facilities were improved to make them functional. The letter also provides several recommendations to maintain momentum for improving functional handwashing facilities.
