Trachoma is a highly contagious pathogen, which is spread by direct contact. Serovars A-C attack the eyes; and can be acquired from insects and flies, and through contact with contaminated objects such as a shared towel. Serovars D-K are sexually acquired, and attack the reproductive and urinary tracts, of both men and women. Serovars L1, L2, and L3 attack the lymphatic system, and cause eye diseases (lymphogranuloma conjunctivitis and lymphogranuloma venereum).
Trachoma can cause many chronic diseases; however, articles discussing trachoma and chronic disease seldom disclose the serovar of trachoma. In arthritis, scientists suggested ocular trachoma may be more likely to cause arthritis than other forms. In diabetes, a retrospective study showed trachoma increased the risk of diabetes; however, the study was not able to determine the serovars that increased the risk.
People can harbor more than one type of trachoma, and different types of trachoma can cause different types of chronic disease. When trachoma is reported as a cause or a risk factor in chronic disease, it would advance understanding to know the serovar. It would also advance public safety, to be aware when serovars A-C are in the community.
