Sure we can go and still should go to the doctor and take medicine for the person who is C”V sick but only on condition that he completely knows with complete faith that these are all just messengers and in truth ONLY HASHEM CAN HEAL HIM FROM HIS SICKNESS. and when he does recover from his sickness he remembers that it was really Hashem who healed him. No matter how many months of operations and doctors he went through and years of medicine prescriptions. Hashem is the master healer of sickness all over the world and can heal everyone immediately from this terrible coronavirus mageifa that millions have already died if we are just all ready to OPENLY CONFESS TO HASHEM AND COME TOGETHER AS A NATION FOR SERIOUS TESHUVA AND ACHDUS ASAP
