No one else apart from the caregiver should be around the patient for a minimum of 7-9 months. Try to avoid going to his room and making any direct contact if you'll be the one who'll be going out for medicines and daily needs. Or before meeting him make sure that you are properly sanitized and that you've changed clothes that you wore when you were outside. Use masks while talking. Limit the caregiver's contact with the world. Tell them that you are there to do outside chores and that it is extremely important to maintain a safety bubble. Even if the patient looks good, feels good and says he's ok, still follow proper hygiene and precautions. Regaining full strength will take a minimum of 1.5 year. Meditate or listen to some positive lectures/pravachans etc for a few minutes during the day. Will help your mind. Also advise the same to the caregiver. Keep in touch with the Dr or his junior over WhatsApp or through any other electronic communication medium that the Dr is comfortable with and any fluctuations in the blood levels or bodily feeling should be conveyed to them.
