It is the second phase of a project which was launched in November with an outreach awareness and registration programme for about 60 percent of Ebeye's population.
The ongoing screening and treatment phase is expected to take up to nine-weeks to complete.
The Health Minister Kalani Kaneko said the Marshalls has one of the highest rates of TB in the world and that it was time to do something about it.
The aim was to screen nearly 7000 Marshall Islanders aged 15 years and over and to treat everyone who tested positive for tuberculosis.
