My question is just as above. If we can keep birds at a distance, how far should they be.
This question was not answered by a nutritionist, however another user commented.
Co-habitating with birds is a bad idea for folks with either lung disease or heart disease. Birds can carry particular bacteria, viruses, fungi, and protozoa that can cause disease even in healthy people. In people who already have lung disease or heart disease it can be a real problem. Look up histoplasmosis, Psittacosis, avian influenza, Newcastle disease (avian pneumoencephalitis), and Allergic alveolitis. In addition to lung infections there are other diseases birds can transmit to humans. Among them are: Salmonellosis (salmonella infection), Campylobacteriosis, Giardiasis, Pasteurellosis, Erysipeloid (very rare), Cryptococcosis, Avian mite dermatitis, and Nontuberculous mycobacteriosis. In general, none of these diseases are enough to warrant not owning a bird in otherwise healthy people. Folks with lung disease and heart disease are both more prone to infections and have a harder time fighting them. If they do need to co-habitate with a bird then it is a good idea to avoid keeping the birds in bedrooms, clean their cages outdoors, and wear a mask when cages are being cleaned. Keep up with annual immunizations (especially flu and pneumococcus) and if you do come down with a respiratory infection, be sure the doc knows about the birds.
