Ocular infection investigations in Cairo's waste disposal sites. PVP-iodine treatment trials.

Investigations were carried out in Cairo's waste disposal sites of the inhabitants of all age groups. Germ-spectrum was analyzed before and after PVP-Iodine-treatment. However, any further dilution of PVP-Iodine in the treatment had no effect on the germspectrum, as hydrochloric acid formation in air, produced by plastic burning causes severe eye irritation and a constant lacrimation. The high germ count of the air in the dwellings and the environment is an additional source of contamination to the conjunctiva.
