Over the past weekend, a widely-circulated rumor on social media said an Ebola infection was confirmed in the eastern Chinese city of Ningbo.
The city's public health bureau refuted the rumor on Monday, saying a Nigerian man kept under observation since Thursday has tested negative for the deadly virus and his body temperature returned to normal on Friday.
So far, no Ebola cases are reported in China. But for people who experienced the deadly SARS and H7N9 bird flu outbreaks, nervousness is regarded as a natural reaction.
China's National Health and Family Planning Commission has put out an alert on the heightened risk of imported cases, given the large number of people travelling across the borders.
It has issued a notice calling for all health and disease control authorities and medical institutions to make self check-ups. They hope to see if sufficient precautions and prevention measures have been put in place by the end of the month.
The commission also has ordered precautionary measures against people who come from the virus-plagued regions or had contact with Ebola patients or people with high fevers from the regions.
In Guangdong, the forefront of the battlefield to keep the virus out of the country, the prevention efforts are under way. Local health authorities have designated medical institutions to screen and treat potential cases.
The industrial southern province faces a high risk of imported cases and faces enormous disease prevention challenges, the provincial entry-exit inspection and quarantine bureau has warned.
With booming economic ties with Africa, Guangzhou, the provincial capital of Guangdong, receives over 160 non-stop flights from Africa per month. Meanwhile, many Africans enter the province after flight transfers at other neighboring overseas airports.
The Canton Fair, China's largest trade fair, held in Guangzhou, mirrors the enormous challenge facing Guangdong as it hosts 200,000 overseas buyers, with up to 20,000 from Africa.
Local health authorities have set up temperature-testing facilities at the entrances to the exhibition centers to ensure any suspected cases are spotted as soon as possible.
"(Ebola) is a nightmare for the world," said James Mwangi, a buyer from Kenya. "I think (Chinese border police) should take more precautions and maybe inspect every person just to ensure that nobody comes in with the disease."
In its latest update, the World Health Organization (WHO) said seven countries have reported over 9,200 confirmed, probable and suspected cases. Of those, more than 4,500 have died.
Liberia, Sierra Leone and Guinea, among the least wealthy nations in West Africa where the disease is prevalent, are the worst-hit.
Currently, the Ebola epidemic has become a prominent challenge for the international community as it still has no effective treatment and vaccines are still under first-stage clinical trials. China has sent batches of supplies and medical staff to help contain the outbreak in western Africa.
