primary prevention of malaria

Lupi E, Hatz C, Schlagenhauf P. The efficacy of repellents against. High doses of chloroquine, such as those used to treat rheumatoid arthritis, have been associated with retinopathy; this serious side effect appears to be extremely unlikely when chloroquine is used for routine weekly malaria prophylaxis.

These include the presence of antimalarial drug resistance in the area of travel (see Chapter 2, Yellow Fever Vaccine & Malaria Prophylaxis Information, by Country), length of travel, the patient’s other medical conditions, allergy history, medications being taken (to assess potential drug interactions), and potential side effects. However, combinations of these medications and additional drugs that are not recommended may be commonly prescribed and used in other countries. 2017 Sep 1;24(6). If this is the case, the traveler can take a dose as soon as possible, then resume weekly doses on the originally scheduled day.

Prophylaxis in areas with mefloquine-sensitive malaria, 228 mg base (250 mg salt) orally, once/week, ≤9 kg: 4.6 mg/kg base (5 mg/kg salt) orally, once/week. Good choice for shorter trips because the traveler takes the medicine once, 1 week after traveling rather than 4 weeks. use of seatbelts and bike helmets) education about healthy and safe habits (e.g. Prophylactic dosing for children weighing <11 kg (24 lb) constitutes off-label use in the United States. A travel health provider advising a traveler going to a country with relatively low malaria transmission for a short period of time and engaging in low-risk behaviors may choose insect avoidance only and no prophylaxis for the traveler. Microscopy can provide immediate information about the presence of parasites, allow quantification of the density of the infection, and allow determination of the species of the malaria parasite—all of which are necessary for providing the most appropriate treatment. In G6PD-deficient people, primaquine can cause fatal hemolysis.

Open trials refer to studies currently accepting participants. In resource-limited settings, and particularly in sub-Saharan Africa, overdiagnosis and the rate of false-positive microscopy for malaria may be high. Plasmodium species are transmitted by the bite of an infective female Anopheles mosquito.

Information about malaria transmission in specific countries is derived from various sources, including WHO (see Chapter 2, Yellow Fever Vaccine & Malaria Prophylaxis Information, by Country). Travelers going to malaria-endemic countries are at risk for contracting the disease, and almost all of the approximately 1,700 cases per year of malaria in the United States are imported.

In addition to using a topical insect repellent, a permethrin-containing product may be applied to bed nets and clothing for additional protection against mosquitoes. For destinations where chloroquine-sensitive malaria is present, in addition to mosquito avoidance measures, the many effective prophylaxis options include chloroquine, atovaquone-proguanil, doxycycline, mefloquine, and tafenoquine. Laboratories that do not provide in-house, on-the-spot microscopy services should maintain a stock of malaria RDTs so that they will be able to perform immediate malaria diagnostic testing when needed. Thus, if the medication needs to be changed because of side effects before a full course has been completed, there are some special considerations (see Table 4-12).
