A study on the prevalence of Toxocara canis in domestic dogs of City of Havana was carried out for the first time in Cuba. 22 dogs were selected in each municipality, totalling 330 as the study universe. Dogs' feces samples were processed through direct examination using Willis' flotation method (1921). The results attained showed a 17.9% prevalence of Toxocara canis, a high figure constituting an important risk factor for transmission to humans. This was influenced by the age of the animals and the hygienic conditions of the houses, significant factors from the epidemiological point of view. Sex did not play a significant role.
在古巴首次对哈瓦那市家犬中的犬弓首蛔虫患病率进行了研究。每个市选取22只狗，共计330只为研究总体。犬粪便样本采用威利斯漂浮法（1921年）进行直接检测。所得结果显示犬弓首蛔虫患病率为17.9%，这一高数值构成了传播给人类的重要风险因素。这受到动物年龄和房屋卫生条件的影响，从流行病学角度来看这些是重要因素。性别未起到显著作用。
