Background: Given the increasing evidence of Plasmodium vivax infections associated with severe and fatal disease, the identification of sensitive and reliable markers for vivax severity is crucial to improve patient care. (fiocruz.br)
The classic symptom of malaria is paroxysm-a cyclical occurrence of sudden coldness followed by shivering and then fever and sweating, occurring every two days (tertian fever) in P. vivax and P. ovale infections, and every three days (quartan fever) for P. malariae. (wikipedia.org)

For successful elimination of vivax malaria, socio-behavioral changes in the communities are essential. (gnu.ac.kr)
capability to cope with anti-malaria programs, the 2 groups of participants shared the same level of awareness about public promotional and educational measures and opinions for malaria elimination from the community. (gnu.ac.kr)
Thus, our future goals for malaria prevention and elimination are to develop more active and well-organized community-based education and evaluation programs collaborating with the community healthcare authorities and local governments. (gnu.ac.kr)

Director to report periodically to the Regional Committee on progress made in control and elimination of malaria. (who.int)
1 Malaria is close to elimination in Vanuatu only in Tafea Province and in Solomon Islands only in Isabel Province. (who.int)

In addition to considering malaria in the differential diagnosis for febrile patients with a history of travel to malarious areas, health-care providers also should consider malaria as a possible cause of fever among patients who have not traveled but are experiencing alternating fevers, rigors, and sweats with no obvious cause. (cdc.gov)
All seven patients reported having no previous history of malaria, recent blood transfusion, organ transplantation, or intravenous drug use. (cdc.gov)
Six of the seven patients reported never having traveled to regions where malaria is endemic. (cdc.gov)
Laboratory confirmed that 12(66.7%) patients had Falciparum malaria, 3(16.7%) mixed Falciparum and Vivax, a patient with Falciparum and SARS-CoV-2 and a patient with dengue and SARS-CoV-2. (tephinet.org)
Background: Thrombocytopenia is often seen in the patients of malaria infected with Plasmodium vivax. (edu.pk)
We studied patients admitted in hospital having coexisting thrombocytopenia and malaria, and recorded the response to anti-malarial therapy. (edu.pk)
Methods: In this cross-sectional descriptive study, a total of 120 patients admitted in medical ward with Plasmodium vivax malaria and co-existing thrombocytopenia were studied. (edu.pk)
Method : Case Control, cases were the patients of malaria vivax who was slide positive vivax plasmodium and uncompliance in taking medicine, control were patients of vivax malaria who was slide pasitive vivax plasmodium and compliance in taking medicine. (undip.ac.id)
Methods and Findings: CNAs levels in plasma from twenty-one acute P. vivax malaria patients from the Brazilian Amazon and 14 malaria non-exposed healthy donors were quantified by two different methodologies: amplification of the human telomerase reverse transcriptase (hTERT) genomic sequence by quantitative real time PCR (qPCR), and the fluorometric dsDNA quantification by Pico Green. (fiocruz.br)
These findings were further sustained when we assessed CNAS levels in plasma samples from 14 additional P. vivax patients of a different endemic area in Brazil, in which CNAS levels strongly correlated with thrombocytopenia (p = 0.0072). (fiocruz.br)
The 407 participants including vivax malaria patients and uninfected inhabitants in Gimpo- and Paju-si, Gyeonggi-do, known as high-risk areas in Korea. (gnu.ac.kr)
The majority of studies reported a significant decrease in GSH levels in malaria patients compared with uninfected controls, and this was confirmed by meta-analysis (P confidence interval [CI] - 2.48 to - 0.46, I2 99.12%, 17 studies). (bvsalud.org)
In conclusion, although GSH levels appear to be generally lower in malaria patients , further detailed studies are necessary to fully elucidate this complex relationship. (bvsalud.org)
We studied VWF release and proteolysis in patients with symptomatic Plasmodium falciparum or P. vivax malaria on the Indonesian island Sumba. (ru.nl)
Malaria patients had significantly lower platelet counts and higher VWF concentrations and VWF activation factors than healthy hospital staff controls. (ru.nl)
A national policy for all patients to receive a diagnostic malaria test if suspected was implemented in 1968. (who.int)

Transfusion transmitted malaria contributes significantly to the burden of malaria in SSA. (who.int)
The greatest malaria burden globally however a major risk for acquiring transfusion occurs in Nigeria, with approximately 51 million transmitted malaria. (who.int)
Afghanistan, Djibouti, Pakistan, Somalia, Sudan and Yemen) have a high burden of malaria and are focusing on malaria control. (who.int)

The WorldWide Antimalarial Resistance Network (WWARN) generates innovative resources and reliable evidence to inform the malaria community on the factors affecting the efficacy of antimalarial medicines. (malaria.com)

The mechanism behind this reduction and the role in malaria pathogenesis needs to be further elucidated. (ru.nl)

Efforts to develop more effective malaria vaccines are ongoing. (wikipedia.org)
We tested the safety and immunogenicity of vaccines composed of P. vivax CS-derived synthetic peptides. (unifesp.br)
These vaccines appear safe, well tolerated, and immunogenic in malaria-naive volunteers. (unifesp.br)

Similarly, no significant variation was observed between symptomatic and asymptomatic malaria cases (P = 0.78, Hedges g 0.06, 95% CI - 0.34 to 0.46, I2 48.07%, two studies). (bvsalud.org)
