Why a person having malarial parasite does not shows symptoms of disease?

Some peoples (ie tribes/families) who have lived in malaria infested regions have developed a natural partial immunity to the parasite (by a process of natural selection and evolution) such people may be infected by the parasite but do not develop full blown malaria because their immune system keeps the parasite in check.
Note, the danger in this is that such people act as the source of malaria affecting others. The mosquito has to bite someone with malaria FIRST then go on to bite a SECOND person. This gives malaria to the SECOND person. Obviously people carrying the malaria parasite but not ill do not go and get treated for malaria (have the parasite in their bodies killed). They therefore act as a hidden reservoir for infection.
