It's about disease caused by the Anopheles mosquito.
The life cycle of malaria parasites in the human body. A mosquito infects a person by taking a blood meal. First, sporozoites enter the bloodstream, and migrate to the liver. They infect liver cells (hepatocytes), where they multiply into merozoites, rupture the liver cells, and escape back into the bloodstream. Then, the merozoites infect red blood cells, where they develop into ring forms, then trophozoites (a feeding stage), then schizonts (a reproduction stage), then back into merozoites. Sexual forms called gametocytes are also produced, which, if taken up by a mosquito, will infect the insect and continue the life cycle.
Ni kisah kitaran hidup si nyamuk bernama Anopheles(female nyer nyamuk yg cause disease called malaria)
Malaria is a mosquito-borne infectious disease caused by a eukaryotic protist of the genus Plasmodium. It is widespread in tropical and subtropical regions, including parts of the Americas, Asia, and Africa. Each year, there are approximately 350–500 million cases of malaria, killing between one and three million people, the majority of whom are young children in sub-Saharan Africa. Ninety percent of malaria-related deaths occur in sub-Saharan Africa. Malaria is commonly associated with poverty, but is also a cause of poverty and a major hindrance to economic development.
Five species of the plasmodium parasite can infect humans; the most serious forms of the disease are caused by Plasmodium falciparum. Malaria caused by Plasmodium vivax, Plasmodium ovale and Plasmodium malariae causes milder disease in humans that is not generally fatal. A fifth species, Plasmodium knowlesi, is a zoonosis that causes malaria in macaques but can also infect humans .
Malaria is naturally transmitted by the bite of a female Anopheles mosquito. When a mosquito bites an infected person, a small amount of blood is taken, which contains malaria parasites. These develop within the mosquito, and about one week later, when the mosquito takes its next blood meal, the parasites are injected with the mosquito's saliva into the person being bitten. After a period of between 2 weeks and several months (occasionally years) spent in the liver, the malaria parasites start to multiply within red blood cells, causing symptoms that include fever and headache. In severe cases, the disease worsens, leading to coma and death.
ade ayat juga dalam Quran berkaitan dgn nyamuk nih..tp dah xingat surah mane??
huhu..kena carik la dlu..take time sket..

Sesungguhnya Allah tidak segan membuat perumpamaan seekor nyamuk atau yang lebih kecil daripada itu. Adapun orang-orang yang beriman,mereka tahu bahawa itu kebenaran dari Tuhan. Tetapi mereka yang kafir berkata, "Apa maksud Allah dengan perumpamaan ini?" Dengan (perumpamaan) itu banyak orang yang dibiarkanNya sesat, dan dengan itu banyak pula orang yang diberiNya petunjuk. Tetapi tidak ada yang Dia sesatkan itu selain orang-orang fasik.
(Al-Baqarah:26)
