    Family infections drive record case numbers

    The number of coronavirus patients recuperating at home hit a record high of more than 430,000 as of February 2. Japan continues to report daily record cases and infections are spreading within families. Confirmed infection routes in Tokyo at the end of last month show about 60 percent of cases developing through transmission from family members.

    The number of patients who are seriously ill is increasing as the Omicron strain takes hold. The central government is trying to put systems in place to provide medicines and health monitoring for patients recovering at home.

    Authorities offer tips and precautions for people to follow while recovering at home. They cover patient care as well as ways to prevent infections spreading within households.
