My husband is currently working in Mozambique, and is sick with a fever, headache, and pain in his joints. Can this be malaria?
It could be. Your husband should go to the clinic and get tested. The standard diagnosis for malaria depends on the demonstration of parasites on a blood smear examined under a microscope. In some settings, where microscopic examination is not possible, or as a quick response, clinics can use an RDT or rapid diagnostic test on a drop of blood. If your husband is in a place without any available testing methods, the health worker may treat him on his symptoms alone (this is called presumptive treatment). It is important to seek care early because if it is malaria it can get serious very quickly.
