Rare locally transmitted cases in the city of Santo Domingo (Distrito Nacional) and other provinces. Factors that affect local malaria transmission patterns can change rapidly and from year to year, such as local weather conditions, mosquito vector density, and prevalence of infection.

Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. Treatment of uncomplicated malaria due to Chloroquine-sensitive Plasmodium species Adults An initial dose of 1 g salt = 600 mg base followed by an additional 500 mg = 300 mg base after six to eight hours and a single dose of 500 mg = 300 mg base on each of two consecutive days. This represents a total dose of 2.5 g Chloroquine phosphate or 1.5 g base in three days. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Several medications are available for chemoprophylaxis. When deciding which drug to use, consider specific itinerary, length of trip, cost of drug, previous adverse reactions to antimalarials, drug allergies, and current medical history.

However, direct proof of a causal relationship has remained elusive and most models have posited a multigenic basis of resistance. Chloroquine resistance CQR was defined as follows CQR Category 1 - 10% recurrences by day 28, the lower 95% confidence interval on this estimate being 5%, irrespective of confirmation of adequate blood chloroquine concentration. Chloroquine phosphate or hydroxychloroquine sulfate Plaquenil can be used for prevention of malaria only in destinations where chloroquine resistance is not present see Chapter 2, Yellow Fever Vaccine & Malaria Prophylaxis Information, by Country.
