Dulfa Elena Perozo Blanco is a doctor and public health management specialist in Caracas, Venezuela. She works at an IDC (integral diagnostic center) in a local community. When the COVID-19 pandemic began in Venezuela, Dulfa and other doctors received both medical supplies, including testing kits, and COVID-19 treatment experience from China. Apart from diagnosing patients and conducting testing in the IDC, Dulfa has also been visiting community residents' homes to check their health statuses. She believes the Chinese model has helped a lot and there were zero confirmed case in the La Pastora parish at the time the video was made. These days, Dulfa's been working tirelessly and sleeping less; all she wants is to help more people and protect them from the virus.
