Health authorities in China are scrambling to allay public fears about
a deadly tick-borne disease that has killed more than 30 people since
2007, but admitted they do not know how many have been infected.
The illness known as human granulocytic anaplasmosis (HGA) has spread
to 12 provinces including Henan in central China and Shandong in the
east, where the deaths have been reported, the China Daily reported
Saturday.
HGA is treatable if detected early. Symptoms include fever, headache
and muscle aches, but the infection can reduce a patient's white blood
cell and platelet count, leading to organ failure and death.
The illness has mainly affected those aged 40 to 70, state media
reported.
"So far we have no details on the general epidemic situation across the
country," health ministry spokesman Deng Haihua told a press conference
on Friday, calling on authorities in affected provinces to report any
cases.
But Deng downplayed suggestions of an official cover-up of the
outbreaks, saying it was simply difficult to raise public awareness
about a little-known infectious disease.
Henan authorities only announced Wednesday that 557 people had been
infected with HGA since May 2007, 18 of them fatally, after a state-run
newspaper reported on a fresh outbreak in the city of Xinyang that
began months ago.
A total of 182 cases have been identified in Shandong since May 2008.
HGA was first detected in Anhui province in 2006. The health ministry
subsequently issued guidelines which stipulate that suspected cases be
reported within 24 hours of detection, the China Daily said.
The health ministry has sent experts to Henan province to assist in
epidemic control work by helping to educate local doctors about the
disease, the paper said.
"It is still difficult to pinpoint the pathogen of the disease since it
may be caused by a new virus," Wang Shiwen, an expert at the Chinese
Centre for Disease Control and Prevention, was quoted as saying by
Xinhua news agency.
