Via FrontPageAfrica: After 100+ Ebola Deaths, Liberia Heeds to Partial Border Closure. After summarizing President Sirleaf's measures, the report goes on to say:
It can be recalled that the opposition Liberty Party during the first outbreak of the deadly disease, called for the closure of the borders with affected neighbors but such recommendations were vehemently rejected by the government.
Following extensive deliberation by the National Executive Committee of Liberty Party at its regular Tuesday meeting, the party has reasoned that it will be in the best interest of Liberia to have its borders with the Republic of Guinea closed in the wake of an outbreak of the deadly Ebola virus in that country which has now entered Liberia,” stated the LP in a statement.
“Liberty Party believes this action will send a clear signal to our citizens, in particular, that the country is faced with a severe health situation that requires stringent measures to protect the lives of its people.”
Even though the [party] recognized the impact such decision would have economically it felt it was prudent for the government to do so and save Liberian lives from the deadly outbreak that was killing people in their dozens at the time in Guinea.
The party stated at the time that it believes that leaving the borders opened to unrestricted human traffic in the wake of the life-threatening virus could be interpreted as a demonstration of insensitivity. But the government paid no heed.
“The party notes that such action comes with corresponding consequences, including economic social and political. However, it believes that nothing is more of an imperative now than securing the health of its people,” stated the LP.
“Meanwhile, in recognition of the porous nature of the borders, Liberty Party further recommends that units of the Armed Forces of Liberia be positioned at strategic points to straightly ensure that there are no movements back and forth until at such time reasonable measures have been taken to contain the pandemic.”
And given the porous nature of West African borders, it's unclear to me how any number of soldiers could effectively seal off Liberia's back country from Guinea and Sierra Leone.
