Three students returning from Nigeria , one of the four countries that reported the spread of Ebola virus, are now in good condition and have been under close observation by the Ministry of Health.

They were directly examined on August 14 by Deputy Minister Nguyen Thanh Long and experts from the World Health Organisation (WHO), the US Centres for Disease Control (USCDC) and the Hanoi Health Department.

The Nigerian students are studying at the FPT University in Hanoi . Two of them entered Vietnam on August 8 while the other, on July 31.

To prevent the spread of the deadly virus into the country, the Ministry of Health has worked with other ministries and agencies to closely monitor visitors to Vietnam at border gates and in the community to detect and quarantine suspected cases early.

In the northern border province of Lang Son , the local quarantine centre has launched an emergency action plan against the epidemic with a range of drastic and urgent measures such as closely supervising visitors from abroad and increasing examination of imported vehicles and goods.

The centre has installed four temperature scanners at the international border gates of Huu Nghi, Tan Thanh and Coc Nam , said its director Ly Kim Soi.

Ebola is a severe acute viral illness often characterized by the sudden onset of fever, intense weakness, muscle pain, headache and sore throat. This is followed by vomiting, diarrhea, rashes, impaired kidney and liver function, and in some cases, both internal and external bleeding.

The virus is caught by close contact with an infected person through bodily fluids such as sweat, blood and tissue.

According to the World Health Organisation, Ebola has killed 1,069 people in the current outbreak, spreading from southern Guinea to Liberia , Sierra Leone and then Nigeria.-VNA
