The World Health Organization expects a more transmissible version of omicron to increase in circulation around the world, though it's not yet clear if the Covid subvariant can reinfect people who caught an earlier version of the omicron strain.
Maria Van Kerkhove, the WHO's Covid-19 technical lead, said Tuesday the global health agency is tracking four different versions of omicron. Van Kerkhove said the BA.2 subvariant, which is more contagious than the currently dominant BA.1 version, will likely become more common.
