As it stands, no, all borders are open to the best of my knowledge.

Senegal closed it's border with Guinea back in April, but it opened again a few weeks later.

Mauritania closed all borders with Senegal back in April too EXCEPT for Rosso and Diama, these crossings remained open.

Absolutely no reports of other borders closing to date, but note:

- Sierra Leone said it closed all of its borders to 'trade' about 6-7 weeks ago. I presume that means what it means (cargo), as it appears people are still crossing at main borders

- It is worth noting that the Ivorian government refused to take 400 refugees back into the country from Liberia a few weeks back, citing the ebola threat as a concern. However, there is possibly a political edge to this decision too (refugess are possible Gbagbo supporters). No reports that the border has closed.

It is a very mixed affair with the latest ebola news. By far the area of greatest concern is the east of Sierra Leone (Kaliahun and Kenema area), and also in Lofa country in Liberia.

Guinea is reporting much less cases in recent weeks, and indeed MSF have closed the treatment centres in Telimele and Macenta due to no new cases for 21 days. However, the lack of new cases in Guinea could be because locals are not attending clinics any longer out of fear. It is too difficult to judge.

Even so, the biggest outbreak in Guinea was and remains in the forest region around Gueckadou. The smaller outbreaks in Boffa, Telimele, Dabola, Karoussa etc appear to be contained. It still rumbles on in Conakry but at a relatively low level considering it was first reported there in March.

There is no certainty what will happen next with regards if the outbreak will be contained, but there does appear to have been a significant push over the past 2-3 weeks to address the failures of the past few months in doing more to stop it spreading. Time will tell.

Authorities all say the risk to travellers is considered quite low as long as sensible precautions are taken.
