What causes malaria and what are its symptoms?

FIRST TIME I HAVE SEEN A POSTING OF THIS SORT.......REALLY NICE...... WELL MALARIA IS CAUSED BY A PARASITE (CALLED PLASMODIUM )THROUGH A (FEMALE ANOPHELES) MOSQUITO BITE ACCORDING TO THE WORLD HEALTH ORGANISATION(WHO)ANY FEVER IS TO BE TREATED FOR MALARIA FIRST AND LATER INVESTIGATED INTO........ SO IT IS EVIDENT THAT FEVER IS THE CHARACTERISTIC SYMPTOM FOR MALARIA....... FEVER WITH CHILLS AND RIGORS IS COMMON......... MAY INCLUDE HEAD ACHE,VOMITING ETC....
