Yes, you can apply for life insurance if you have had COVID-19. However, you must wait for a period of time after full recovery before applying. The wait time depends on the severity of your illness:
If your illness was mild and you did not require any inpatient therapy, you can apply four weeks after full recovery from any symptoms.
If you required non-intensive inpatient therapy (no ventilator, etc.), you can apply four to six months after full recovery from any symptoms.
If you required intensive inpatient therapy (ventilator, etc.), you can apply six months after full recovery from any symptoms.
