There can be a delay of one week to one year between getting infected and having symptoms.<\/p>\n<p>Most people who grow up in malarial areas have some immunity to the illness. Malaria is usually an <strong>acute<\/strong> (short-term) illness, but for some people it becomes a <strong>chronic<\/strong> (life-long) problem.<\/p>\n<p>The risk of malaria is related to where you live and whether this is in a high-risk country or region, and by season. Malaria is the one of the leading causes of death in children under 5 who live in areas affected by malaria.<\/p>\n<p>In people with HIV:<\/p>\n<ul>\n<li>Acute malaria infection is <strong>not\u00a0<\/strong>an OI.<\/li>\n<li>Chronic malaria is considered a <strong>coinfection.<\/strong><\/li>\n<\/ul>\n<h2 id=\"main\">Main symptoms<\/h2>\n<ul>\n<li>Shaking chills.<\/li>\n<li>High fever and sweating.<\/li>\n<li>Dizziness, nausea, vomiting, abdominal cramps.<\/li>\n<li>Headache and back ache.<\/li>\n<li>Tiredness.<\/li>\n<li>Sometimes jaundice (yellowing of skin and eyes).<\/li>\n<\/ul>\n<p>Malaria attacks happen over 4 to 6 hours, and occur every 2 or 3 days.<\/p>\n<p>If malaria affects the brain, it can be fatal within 24 hours.<\/p>\n<p>Malaria can cause anaemia.<\/p>\n<h2 id=\"both\">Malaria and HIV<\/h2>\n<p><strong>HIV increases the\u00a0risk of malaria infection, and the malaria\u00a0is more severe.

This has to be taken very seriously and managed appropriately.<\/p>\n<p>This usually means that the risks from not treating malaria are greater than the difficulties from treatment (ie drug interactions).<\/p>\n<h2 id=\"diagnosis\">Diagnosis<\/h2>\n<p><strong>Malaria is diagnosed by physical examination and blood tests.<\/strong><\/p>\n<p>Information about travel history and symptoms are important.<\/p>\n<h2 id=\"treat\">Treatment<\/h2>\n<p><strong>Malaria can be treated with inexpensive drugs and can usually be cured.<\/strong><\/p>\n<p>The choice of drugs depends on whether the malaria in your region has developed resistance to treatment.<\/p>\n<p>Malaria is usually treated with a combination of drugs.
