Cat Heartworms

Heartworm disease is a serious and potentially fatal disease with worldwide distribution and endemic in many countries including Malaysia. Heartworm is transmitted by mosquitoes and causes no signs of illness initially. As they grow in the heart and blood vessels, they can cause severe lung and heart damage.

Lifecycle of Cat Heartworm

Mosquitoes are the vectors for heartworm, and dogs can get heartworm too.

Mosquito as vector

Mosquitoes bite infected dogs or cats and draw in blood in which microfilaria are circulating.

L3 Larvae

After 2-3 weeks, the microfilaria develop into the "infectious" third-stage larvae (L3) in the mosquito.

Transmission of Heartworm

Mosquitoes bite healthy cats, and the third-stage larvae enter the cat's body through the bite wound.

Migration of Larvae

The larvae develop between tissues and gradually migrate to the pulmonary artery and heart.

Adult Heartworm

Seven to eight months after infection, heartworms develop into adults and parasitize the pulmonary artery and heart.
