GUANGZHOU: A new and often deadly virus which is sweeping the globe has infected thousands, with no apparent regard for race, gender or nationality. But one group has so far come through virtually untouched – children.
Doctors are trying to explain why a virus that moves with relative ease through the adult population, so far infecting 3,000 worldwide with more than 100 dead, has come up against something of an immunological wall when it comes to youngsters.
In this south China city, just kilometres from where the outbreak began, Guangzhou Children's Hospital has yet to see its first patient with Severe Acute Respiratory Syndrome (SARS), officials said this week.
“We haven't had any cases of SARS,” said Yu Minghua, chief of paediatrics at south China's largest hospital for children. “No one has died and no one has been on a respirator ... This hospital has about 300 doctors, and none of them has got SARS either.”
China, especially southern Guangdong province where the disease emerged in November, has been criticised by the World Health Organisation (WHO) for not fully reporting the real number of SARS cases early enough.
But the resistance of children to SARS is a phenomenon that is seen in other places where the disease has struck hardest.
In Singapore, just three of the 126 cases to date, or 2.4%, are children under the age of 18, according to government data published on Thursday.
Out of about 1,000 sufferers in Hong Kong, “the number of children infected with SARS is low ... and they had close contacts with SARS patients before infection,” Hong Kong's Department of Health said in a statement. It said more specific data was not available.
A Chinese official could not say how many of the 1,206 people who have come down with the disease in Guangdong were children.
But Yu said that no children with SARS had come through her hospital, as one might suspect, before being transferred to Guangzhou's No. 8 People's Hospital where many of the city's SARS sufferers have been quarantined.
Just two weeks ago, when first Singapore and then Hong Kong closed schools to prevent the disease's spread, less was known about who gets the disease.
The Hong Kong suspension of classes was later extended through the Easter holidays, while Singapore began a graduated reopening of its schools on Wednesday.
The latest research, published by two teams in the New England Journal of Medicine on Thursday, identifies the virus as a completely new version of the coronavirus family, the infection that causes the common cold, among other diseases.
To date, however, doctors have found no clear evidence that SARS is spread through children-to-children contact either in or outside schools, said C.K. Li, a paediatrician at Prince of Wales Hospital, where most of Hong Kong's first SARS cases came.
“Initially when I saw the first one or two cases (of children with SARS) I was in great worry that they would spread that disease within the schools,” he said. “But that has never happened within Hong Kong.”
Deng Li, who heads the respiratory department at Guangzhou Children's Hospital, said it was not uncommon for children to get some respiratory diseases that adults don't get and vice versa, and that that may be the case with SARS. – Reuters
