Chicago: The continued spread of the SARS-COV-2 virus has spawned a Greek alphabet of variants a naming system used by the World Health Organizntion to track concerning new mutations of the virus that causes Covid-19.Some have equipped the virus with better ways of infecting humans or evading vaccine protection.Scientists remain focused on Delta, now the dominant variant rising rapidly around the world, but are tracking others to what may one day take its place.The Delta variant first detected in India remains the most worrisome.It is striking unvaccinated populations in many countries and has proven capable of infecting a higher proportion of vaceinated people than its predecessors.The WHO classifies Delta as a variant of concern, meaning it has been shown capable of increasing transmissibility, causing more severe disease or reduce the benefit of vaccine and treatments.According to Shane Crotty, a virologist the La Jolls Institute for immunology San Diego, Delta's "superpower" is its transmissibility.Chinese researchers found that people infected with Delta carry 1,260 times more virus in their noses compared with original version of the corena virus.Some US research suggest that the "viral load" in vaccinated individuals who become infected with Delta is on par with those who are unvaccinated, but more research is needed.
1. what is dominant variant rising rapidly around the world?
2. why are vaccinated people not safe?
3. How does WHO classify Delta?
4. what is the suggestion of some US research?

Answer:
vTaxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world. Using morphological, behavioural, genetic and biochemical observations, taxonomists identify, describe and arrange species into classifications, including those that are new to science. Taxonomy identifies and enumerates the components of biological diversity providing basic knowledge underpinning management and implementation of the Convention on Biological Diversity. Unfortunately, taxonomic knowledge is far from complete. In the past 250 years of research, taxonomists have named about 1.78 million species of animals, plants and micro-organisms, yet the total number of species is unknown and probably between 5 and 30 million.
