What are the symptoms of malaria? when should i be worried?

Malaria: The presentation may vary with the plasmodium species involved but often begins with shaking chills, high fevers, sweats, headache, fatigue and nausea and vomiting. In persons who have been in a malarious area for very long and have been repeatedly infected there may be minimal if any symptoms. It also varies with the state of the infected individual.

Agree w Dr. Raff: Malaria Symptoms may include: headache, fever, shivering, sweating, fatigue, nausea, vomiting, dry cough, muscle/joint/back pain & enlarged spleen. There is a cyclic pattern of being very cold & shivering followed by feeling very hot and sweating. Additionally one can develop jaundice, blood in urine, anemia, eye problems (nystagmus, problems with eye movements), seizures & coma. Would be >
