China reports over 280 cases of tick-borne disease this year
16:22, June 17, 2011

As of June 16, more than 280 cases of tick-borne disease have been reported in central and east China's provinces of Henan, Hubei, Shandong, Anhui and Jiangsu, according to the Chinese Center for Disease Control and Prevention (CDC).

A dozen people have died from the disease. Ninety percent of the cases occurred in people over 40 years of age and farmers accounted for 90 percent of these cases.

The tick-borne disease, named by the center as "fever-thrombocytopenia syndrome," is a kind new infectious disease caused by Bunia virus found in central China regions. The CDC said that most of the victims have suffered from nausea, fatigue and a lack of appetite.

In October of last year, the Ministry of Health issued a guideline on the control and prevention of tick-borne diseases, asking local governments to report on possible cases through a nationwide disease control network.

As of 16 Jun [2011], more than 280 cases of tick-borne disease have
been reported in central and east China's provinces of Henan, Hubei,
Shandong, Anhui and Jiangsu, according to the Chinese Center for
Disease Control and Prevention (CDC). A dozen people have died from
the disease. 90 per cent of the cases occurred in people over 40 years
of age, and farmers accounted for 90 per cent of these cases.

The tick-borne disease, named by the center as
"fever-thrombocytopenia syndrome," is a new infectious disease caused
by Bunia virus [Bunyavirus] found in central China regions. The CDC
said that most of the victims have suffered from nausea, fatigue and a
lack of appetite.

In October of last year [2010], the Ministry of Health issued a
guideline on the control and prevention of tick-borne diseases, asking
local governments to report on possible cases through a nationwide
disease control network.

[The etiological agent in these cases is severe fever with
thrombocytopenia syndrome (SFTS) virus, a newly identified member of
the genus phlebovirus in the Bunyaviridae family (see ProMED-mail
archive no. 20110317.0853). The virus has been isolated from blood of
2 patients and from _Haemaphysalis_ ticks collected from dogs.
Isolation of the virus from ticks does not prove their vector
capacity, nor from dogs indicates that they are competent sources of
infectious blood meals for arthropod vectors, but these findings do
indicate that laboratory susceptibility and transmission experiments
are worth doing.
