A screenshot from Facebook of Colosbaby advertisement in Vietnam that featured the World Health Organization’s (WHO) Director-General headshot with a caption at the top, “WHO raises COVID-19 threat warning to its highest level”. “The world is entering a decisive moment when coronavirus disease is spreading more rapidly” appeared like a quote from him. Next to the products were captions “ColosBaby Boost immune system” and “Prevent respiratory and digestive infections caused by viruses and bacteria” (translated from Vietnamese).
