Rate of pertussis among U.S. population by state 2018

The states with the highest rates of pertussis include Vermont, Wisconsin, Alaska and Maine. Pertussis is more commonly known as whooping cough. It is a respiratory disease that causes uncontrollable coughing. Whooping cough is highly contagious, but deaths are rare. Pertussis vaccination There are two vaccines in the U.S. that help to prevent pertussis. These are the DTaP, for children under 7 years, and the Tdap, for older children, teens and adults. These vaccines are highly recommended, and a majority of children and teens receive them. In 2017, around 83 percent of children aged 19 to 35 months had received the DTaP vaccine. Pertussis cases The number of cases of pertussis in the United States have decreased significantly since the introduction of vaccines that prevent the disease. In 1950, there were around 120,700 new cases of pertussis in the U.S., compared to just under 18,000 new cases in 2016. In that year, there were around 5.56 new cases of pertussis per 100,000 population.

美国罹患百日咳（亦称百日咳）率最高的州包括佛蒙特州、威斯康星州、阿拉斯加州和缅因州。百日咳是一种导致无法自控咳嗽的呼吸道疾病。百日咳具有高度传染性，但死亡病例极为罕见。美国目前有两种疫苗可预防百日咳，分别为适用于7岁以下儿童的DTaP疫苗和适用于年长儿童、青少年及成人的Tdap疫苗。这两种疫苗被高度推荐，大多数儿童和青少年都已接种。至2017年，约83%的19至35个月大的儿童已接种DTaP疫苗。自引入预防百日咳的疫苗以来，美国百日咳病例数显著下降。1950年，美国约有120,700例新的百日咳病例，而2016年新病例数仅为18,000例左右。当年，每10万人中约有5.56例新的百日咳病例。
