(Reuters Health) - New mothers with hepatitis B can safely breastfeed their babies, as long as they take a few important precautions, according to a new study.

The hepatitis B virus causes inflammation and swelling of the liver and can lead to chronic damage on the organ. The infection is spread through blood, unclean needles, and sex. It may also pass from a mother to her baby during pregnancy and labor.

It has been unclear whether breastfeeding may also transmit the virus, researchers say in the Archives of Pediatrics & Adolescent Medicine.

Their report, a review of past studies, allays those fears.

Even in mothers with the virus, "breastfeeding should be recommended as a valuable source of nutrition to infants," study author Dr. Zhongjie Shi of Temple University in Philadelphia told Reuters Health in an email.

The researchers combined data from 10 previous studies, all conducted in China, which compared rates of hepatitis B in the babies of more than 1,000 mothers with the virus. About half of those mothers breastfed their babies.

To prevent transmission of hepatitis B from the mom, babies are given a vaccine and another injected medication soon after birth, and are vaccinated two or three more times during the first few months of life.

By their first birthday, 31 babies out of the 637 with breastfeeding mothers tested positive for hepatitis B. That compared to 33 babies out of 706 who had mothers who didn't breastfeed.

Most of those infants, the researchers explained, had been infected with the virus during pregnancy or childbirth.

Shi said that blood is the easiest way for hepatitis B to travel from mother to baby, followed by amniotic fluid and vaginal secretions. He added that hepatitis B is up to 100 times more infectious HIV.

Moms should avoid breastfeeding if they have cracked or bleeding nipples or lesions on their breasts, the authors note, as that could be a way to transmit the virus more easily.

According to the World Health Organization, about 350 million people worldwide are living with chronic hepatitis B infection, while as many as 2 billion have been infected. About one in four people infected with the virus as a child ultimately die of liver cancer or liver scarring caused by the disease.

Shi concluded that while more studies on this topic are needed, the new results "are most valuable in developing countries and areas with high (hepatitis B) prevalence or heavy population, such as India, China, (and) south east Asia."

（路透社） - 乙肝新妈妈母乳喂养的婴儿可以放心，只要他们采取了一些重要措施，根据一项新的研究。

B型肝炎病毒引起的肝脏炎症和肿胀，并可能导致慢性损伤的器官。感染是通过血液传播，不洁的针头，和性别。它也可以通过从一个母亲在怀孕期间和劳动给婴儿。

据还不清楚是否母乳喂养可能传播病毒，研究人员说，在儿科和青少年医学档案。

他们的报告，对过去研究的审查，allays这些恐惧。

即使在与病毒的母亲，“喂奶应被视为一个宝贵的营养来源，婴儿建议”研究项目负责人施中捷费城坦普尔大学在电子邮件中告诉路透社记者。

研究人员结合以前的研究数据来自10个，所有在中国，其中比较了1000多个病毒的母亲与婴儿进行乙肝率。大约半数的母亲用母乳喂养她们的婴儿。

为了防止乙肝传播的妈妈，婴儿给出一种疫苗，出生后不久又注射用药，并注射疫苗，在生命的最初几个月内两个或三个以上。

通过他们的第一个生日，31出了637婴儿哺乳的母亲为B型肝炎检测阳性，相对于33名新生婴儿有706谁的谁没有过母乳喂养的母亲。

这些婴儿大多数情况下，研究人员解释说，已感染了病毒在怀孕期间或分娩。

石广生说，血液是最简单的方式乙肝旅行从母亲到婴儿中，羊水和阴道分泌物其次。他补充说，乙型肝炎是高达100倍以上的艾滋病毒感染。

妈妈们应该避免母乳喂养，如果他们已经找到了破解的胸部或乳头出血或病变，作者指出，因为这可能是传播病毒的方法更容易。

根据世界卫生组织，全球约有3.5亿人患有慢性B型肝炎感染，而多达2亿人受感染。关于在与病毒感染作为一个孩子，最终死于肝癌或肝四人一疤痕引起的疾病。

施认为，关于这一主题的同时，需要更多的研究，新成果“在发展中国家和最高（乙肝）的国家和地区的宝贵患病和沉重的人口，如印度，中国，（和）东南亚。”
