Vanuatu: Elevated malaria activity reported in Vanuatu through July

Event

Health officials reported 576 malaria cases in Vanuatu Jan. 1-July 16, a 75 percent increase when compared to cases identified over all of 2021. Sanma is the most affected province, followed by Malampa, Shefa, and Torba. This report represents the most complete data available as of Aug. 2.

Context

The risk of malaria infection is intermediate and exists nationwide. Authorities reported 507 cases of malaria nationwide in 2020, and 576 cases in 2019.

Malaria is transmitted through the bite of an infected mosquito. Symptoms of malaria most commonly include fever, chills, headaches and body aches, nausea and vomiting, and general malaise. Symptoms typically appear 7-30 days after being bitten; however, there are reports of symptoms beginning as late as one year. Preventative medications (prophylaxis) are available.

Advice

See a medical provider to discuss the need for anti-malarial medication before traveling to Vanuatu. Avoid mosquito bites and remove standing water to reduce the number of biting mosquitoes. Seek medical attention if symptoms develop within a month of being in affected areas; however, be sure to inform a healthcare provider of any travel to affected areas that occurred during the past 12 months.
