It is highly contagious and is spread from person to person through tiny droplets in the air after an infected person coughs or sneezes. Travellers should ensure that they are up-to-date with all of their routine vaccinations which includes the Measles vaccination.

Seven people have died in the capital of Liberia, Monrovia – first deaths in that city since the outbreak began.
