It's been 100 days since the World Health Organization (WHO) was first alerted to a virus that would later be known as COVID-19.

This particular strain of coronavirus has spread across most parts of the world since the start of the year.

While virologists and health experts try to research and understand the nature of the new pandemic. Governments have introduced measures to contain its spread.

People across the world are now housebound, only leaving their homes to buy essential groceries or medicines, limiting all social interactions and trying to protect the elderly and those with existing health conditions.

Tedros Adhanom Ghebreyesus, the WHO's director-general, has been issuing regular updates since the start of the global health crisis to the media and health professionals.
