we were a bit cautious as we had planned to spend 5 years about . just travelling the coast of africa . give or take a thousand miles or so in places . we were traveling in a vw van so facilities at times would have been minimal. if it had been a 6 month dash to south africa i might not have had so many . never heard of ebola then .
