A risk factor is something that increases your chances of getting a disease or condition. Each of the multiple kinds of chlamydial infection has a different set of risk factors and can be considered a separate disease entity.
Sexually transmitted chlamydial infections are transferred from one person to another by direct contact with genital tissues. Chlamydia is highly contagious and one of the most common sexually transmitted disease.
Risk Factors for Chlamydial STDs
Age: 15-25 years old
is more common in females.
Lymphogranoloma venereum (LGV) is six times more common in males.
LGV is another sexually transmitted disease that is caused by the chlamydia bacteria.
Neonatal chlamydia is the same organism transmitted during childbirth from an infected mother to her baby. It accounts for 30%-50% of
and is so common that every newborn in the US is treated to prevent it. Infants born to infected mothers are at risk of developing chlamydial conjunctivitis (in 25% of cases) and chlamydial pneumonia (in 16% of cases).
Risk Factors for Respiratory Chlamydia
Chlamydia bacteria that infect the respiratory system are a different species and enter the body when they are inhaled. These germs in spore form are wafted into the air from infected birds. The risk is limited to those in contact with infected birds. The organisms which cause respiratory chlamydia are related to, but different from, the chlamydia organism which causes sexually transmitted disease. You cannot get any kind of sexually transmitted disease from contact with birds.
Risk factors for respiratory chlamydia include contact with birds, especially psittacines (parrots, parakeets, budgies), but also barnyard birds (ducks, chickens, and turkeys), pigeons, and most other kinds.
Risk factors for Ocular Chlamydia
Trachoma is yet another chlamydial infection by a different strain of this group of germs. Trachoma causes ocular chlamydia. The germ is carried from one person to another by direct contact or by intermediate objects known as fomites.
The risk of acquiring trachoma is high in endemic areas such as Africa, India, Southeast Asia, and the Middle East, and especially for children. Risk factors include:
Flies in developing countries, also objects that can transmit germs—such as towels, washcloths, and fingers
