COVID-19 is a disease that originates in emerging countries. Developing countries are not well prepared to eradicate this disease. It makes victims every day. This special issue dedicated to the coronavirus (COVID-19) will allow developing countries to quickly know the elements necessary to avoid COVID-19. In Cameroon, in two weeks we went from 25 to 70 infected patients. The release of these preliminary data will help infected and uninfected patients and decision-makers in the international fight against this new virus. It is the current pandemic that threatens the whole world. It was detected in china a few months ago and it has become the subject of numerous public and private debates. We investigate the contraction and prevention of the COVID-19 and we found that this virus is spreading rapidly. It is also found that covid-19 is the most easily infecting virus up to now: from human to human at room temperature just by sharing the same space and material (glass, metal plastic etc…) because the agent of covid-19 can remain active on such material up to 9 days. We also present some precaution methods as disinfection of material and our life space. In addition, we offer strategies and tips to avoid contracting COVID-19.
