Malaria Surveillance - United States, 2013.

This report summarizes cases in persons with onset of illness in 2013 and summarizes trends during previous years. DESCRIPTION OF SYSTEM: Malaria cases diagnosed by blood film, polymerase chain reaction, or rapid diagnostic tests are mandated to be reported to local and state health departments by health care providers or laboratory staff. Case investigations are conducted by local and state health departments, and reports are transmitted to CDC through the National Malaria Surveillance System, National Notifiable Diseases Surveillance System, or direct CDC consultations. CDC conducted antimalarial drug resistance marker testing on blood samples submitted to CDC by health care providers or local/state health departments. Data from these reporting systems serve as the basis for this report. RESULTS: CDC received 1,727 reported cases of malaria, including two congenital cases, with an onset of symptoms in 2013 among persons in the United States. The total number of cases represents a 2% increase from the 1,687 cases reported for 2012. Plasmodium falciparum, P. vivax, P. malariae, and P. ovale were identified in 61%, 14%, 3%, and 4% of cases, respectively. Forty (2%) patients were infected by two species. The infecting species was unreported or undetermined in 17% of cases. Polymerase chain reaction testing determined or corrected the species for 85 of the 137 (62%) samples evaluated for drug resistance marker testing. Of the 904 patients who reported purpose of travel...

(Abstracted from Lancet 2019;393:1428–1439.) In Africa, malaria in pregnancy presents a risk to 50 million women each year due to Plasmodium falciparum infection. Although women in endemic areas are typically asymptomatic when infected with malaria parasites, the infection is associated with maternal anemia and adverse birth outcomes including miscarriage, stillbirth, preterm birth, low birth weight, and infant mortality.

CONCLUSION: This study has shown that malaria in pregnancy causes a significant decrease in the platelet count and prolongation in the prothrombin (PT) and the activated partial thromboplastin time (APTT). There is need for the malaria and haemostatic parameters to be assayed routinely on pregnant women particularly those presenting to antenatal clinic with febrile illness.

The objective would be a drug with> 95% efficacy and that is easily tolerated, including in children and pregnant women. For individuals who prefer weekly rather than daily drug administration, a further objective is a product that is administered weekly. The deficiencies of present agents are parasite resistance to chloroquine, neuropsychiatric liability of mefloquine, the need for daily dosing for atovaquone-proguanil, and daily dosing plus adverse reactions for doxycycline. A primaquine analogue, tafenoquine has a 17-day half-life and was approved for weekly prophylaxis in the United States and in Australia in 2018. ...

This study aimed to determine the prevalence, to describe the clinical presentation, and to examine factors associated with congenital malaria in newborns aged up to 7 days attending Tororo General Hospital in Uganda. A total of 261 mother/baby pairs were recruited in this cross-sectional study. Giemsa-stained thick blood smears for malaria parasites and rapid malaria diagnostic tests were performed on capillary blood samples from all newborns and mothers, as well as on placental and cord samples from newborns delivered in the hospital. The prevalence of congenital malaria in the newborns was 16/261 (6.1%). No single clini...

We present here the results of a cross-sectional study conducted in Madibou, a southern district of Brazzaville in the Republic of Congo, between March 2014 and April 2015. The main aim was to characterize P. falciparum infections. Blood samples corresponding to peripheral, placental and cord from 370 asymptomatic malaria women at delivery were diagnosed for plasmodium infection by thick blood smears (microscopic infection). Sub-microscopic infection was detected by PCR, using the MSP-2 gene as marker. Microscopic infections were detected in peripheral, placental and cord blood samples with a prevalence of respectively 7.3...

The objective of the study was to estimate the malaria incidence attributable to the 2013 flood in Almanagil Locality, Gezira State in central Sudan. Methods Study Area Gezira State is located in the east-central region of Sudan, is crossed by the Blue Nile and is irrigated by two canals of the Gezira and Managil agriculture schemes. Almanagil Locality was in 2013 one of the 8 localities that constituted the Gezira State and was situated in the south western part of the state. Almanagil Town, the capital of the locality, is 62 km away from Wadmedani, the capital of Gezira State, and 156 km from Khartoum, the capital o...
