LLIN and malaria: what to know

LLIN means long-lasting insecticidal net. The net creates a physical barrier while its treated fibres deter or kill mosquitoes that come into contact with it. It protects only when it is correctly fitted and used, and it does not treat malaria after infection.

Malaria can cause fever, chills, sweating, headache, weakness, and muscle aches. Symptoms may begin after travel or time in an area where malaria occurs, and they can become serious quickly. A net is one prevention measure; it does not replace travel advice, repellents, suitable clothing, or prescribed prophylaxis.

Hang the LLIN so it fully covers the sleeping space, tuck the edges beneath the mattress or sleeping mat, and check for holes before use. Keep the net away from flames and sharp objects. Follow the care instructions supplied with it; harsh washing or repeated treatment can reduce its protective properties.

Use the net every night, including when windows are open or the room feels cool. Before travel, arrange a travel health consultation to discuss destination risks and malaria prophylaxis. If you develop a fever during travel or after returning, tell the clinician where you have been and when.

Seek urgent medical care for fever with confusion, fainting, difficulty breathing, repeated vomiting, a seizure, extreme weakness, or inability to drink. Malaria can worsen rapidly, so do not wait for symptoms to become severe if you have recently visited a malaria-risk area.

Arrange prompt assessment for fever, chills, or muscle aches after travel, even if symptoms improve. A blood test may be needed, and a negative early result does not always settle the question if symptoms continue; follow the clinician's advice about repeat testing.

Ask: Is my destination a malaria-risk area? Which prevention measures suit my trip? How should I use and care for this LLIN? How long after travel should I watch for symptoms? Where should I seek testing if fever develops?
