A previous infection provided moderate protection from reinfection with omicron BA.1 (45 percent), compared with stronger protection against pre-omicron variants (82 percent). They say Omicron is very contagious, more so than Delta. However, the relationship between duration of virus shedding and infectivity of Omicron is unknown.
