COVID-19 –
Delta Variant

Delta variant (B.1.617.2 and
descendant lineages) was first
identified in India in May 2021
and is currently the dominant
strain in many parts of the
world. It has multiple
mutations, including one that
makes it more transmissible
than previous strains. Studies
suggest that it may cause more
severe illness. Symptoms
associated with the Delta
variant are similar to those of
other variants and can include
mild headaches, fever,
persistent cough, sore throat.
