Conclusion
The epsilon variant of coronavirus was ~20%
more transmittable then previous one and for
some time was “variant of concern” by WHO, but
has been supplanted by a more contagious alpha
strain in short term of time. Any variant of SARSCoV-2 is still very dangerous, so the best thing is
to follow the prevention measures
