An outbreak of systemic toxoplasmosis occurred in October 1977 in Atlanta, Georgia. Thirty-seven people became ill and/or had serologic evidence of acute infection. Epidemiologic study by the Center for Disease Control (CDC) suggested that toxoplasma oocysts from infected cats in a riding stable were the source of infection. Aerolization of oocysts or hand-to-mouth contact were the presumptive means of transmission. All patients were examined and followed for over a year, without evidence of toxoplasma retinochoroiditis. In a four-year follow-up study, only one patient had shown evidence of ocular disease. This suggests that at least some sporadic cases are due to acquired toxoplasmosis.
1977年10月，佐治亚州亚特兰大市爆发了系统性弓形虫病。37人患病和/或有急性感染的血清学证据。疾病控制中心（CDC）的流行病学研究表明，一家马术训练场中受感染猫的弓形虫卵囊是感染源。卵囊的气溶胶化或手口接触被认为是传播途径。所有患者均接受了一年多的检查和随访，未发现弓形虫视网膜脉络膜炎的证据。在一项为期四年的随访研究中，只有一名患者出现了眼部疾病的证据。这表明至少一些散发病例是由后天获得性弓形虫病引起的。
