Health professionals from Papua New Guinea and Niue will attend a week-long workshop on detecting typhoid in Port Moresby next week.
This is the second regional training of this nature.
A Secretariat of the Pacific Community's Preparedness Specialists says typhoid fever is among the top 10 causes of death in Papua New Guinea.
Dr James Wangi says it can be treated with antibiotics, but the tests to detect the disease are often not available in Pacific Island nations.
The training will give the participants the skills to detect and investigate outbreaks of typhoid fever and other foodborne diseases.
