From BBC News:
The number of children infected with a deadly virus in eastern China has increased by nearly 700 in the past two days. The virus, Enterovirus 71, has killed 20 children since it was discovered in Fuyang, a city in Anhui province.
State media said the number of cases had now increased to nearly 1,900. The outbreak began in early March, but was only reported this week – leading to accusations by Chinese press of a cover-up by local authorities.
