If you’re planning a journey to a large city, first consider the personal dangers. One immediate concern is the spreading coronavirus disease. Exposed in many large cities are thousands of homeless people, living in cars, tents and on the sidewalks. Every day, newly-arrived poor bring with them new infections, ongoing illnesses and other contagious conditions.
For your own health concerns, don’t give them money nor otherwise physically touch them. Most effectively, if you want to help, make contributions to the Red Cross, Salvation Army or other legitimate organizations that offer daily aid to city street people.
