When parents go to work, their young children often spend the day in child care. That contact with other children can make it easier to get sick.
当父母上班时通常将孩子送到托儿所。在托儿所与其他孩子的接触使得孩子更容易生病。
But new research suggests that this might have a protective effect a few years later when children start school.
但新的研究表明，这可能会在孩子几年后开始上学时起到一种保护作用。
Sylvana Cote at the University of Montreal led the research team. She says some of the children were more likely to get sick from the kinds of infections commonly passed around a day care center.
蒙特利尔大学的西尔瓦纳·柯特（Sylvana Cote）领导了这个研究小组。她称，有些儿童更可能感染各种通常在日间护理中心传播的疾病。
But she says these children were also more likely to avoid infections when they entered elementary school a few years later.
但她表示，这些儿童在几年后上小学时也更可能避免感染。
