Here is a certificate course which is highly informative and educative designed in line with WHO/ CDC/ NHS guidelines on Covid19. There are four chapters as to how to break the chain.
After the end of each chapter, there are a set of questions you need to answer. Then, you can become an Ambassador for breaking the chain of covid19 infection...you get one certificate too..apart from learning the basics of covid19..
Do a favour to yourself, your family and to your community...
I encourage all to undergo this course which is free to everyone who takes it I have done it... It took me 45 minutes.
Thanks!
