What is the News?
The World Health Organization(WHO) has announced that it would unveil a new naming system for Virus Variants. The system would be similar to the way tropical storms are named.
What is the current method of naming Virus Strains?
- Currently, WHO and other agencies across the world refer to viruses and their variants by formal lineage names. It is a combination of letters and names that point to the relationships between different variants.
- Example: Variants such as B.1.1.7 and B.1.617 are named after mutations in common and as well clues to their evolutionary history.
- Geographical tag: The virus names and their associated diseases have also been frequently named after geographical places where outbreaks were first reported or samples first isolated.
- Example: West Nile virus, Ebola, U.K Strain(B.1.1.7) and South African Strain(B.1.351).
What is the problem with this method of naming strains?
- The current method is stigmatizing and disincentivizing countries from making their sequencing results public as the virus strains are associated with the geographical tag.
- Moreover, the current naming of virus variants is also difficult to remember for the public due to complicated lineage numbers.
What will the new method be like?
- The new method of naming virus strains would be similar to the way tropical storms are named.
- For the naming of tropical storms, the World Meteorological Organisation (WMO) leaves it to countries that surround a particular ocean basin to come up with names.
