Answer

Bacterial conjunctivitis is common worldwide. The estimated incidence of bacterial conjunctivitis in the United States is 135 cases per 10,000 population annually, [4] constituting approximately 1% of all primary care consultations. [10] ​Internationally, isolated epidemics can be devastating in areas affected by blinding infections of newborns, especially in areas heavily affected by C trachomatis, [11] which can cause blindness in up to 8% of the population. [12] Staphylococcal infection was the most common etiology in Paraguay, [13] Pseudomonas in Thailand, [14] and streptococci in India. [15]
