Endemic in emerging and developing regions, like most countries in Latin America, tropical infections are an important cause of morbidity and mortality in this population. Tropical infections in KT recipients may exhibit different pathways for acquisition compared with those in nonrecipients, such as transmission through a graft and reactivation of a latent infection triggered by immunosuppression. Baf-A1 Clinical presentation may differ compared with that in immunocompetent patients, and there are also particularities in diagnostic aspects, treatment, and prognosis. KT patients must be screened for latent infections and immunized properly. Last, drug-drug interactions between immunosuppressive agents and drugs used to treat tropical infections are an additional challenge in KT patients. In this review, we summarize the management of tropical infections in KT patients.Large household surveys performed to estimate coverage rates for various health interventions, including intermittent preventive treatment, depend on recall. Many studies question the validity of recalled data. Regarding vaccine coverage rates, it is standard practice to validate responses using medical history cards. To validate the coverage rates of intermittent preventive treatment during pregnancy reported by large household surveys, recalled coverage rates were compared with antenatal care card data in Benin, Ghana, Malawi, and Tanzania. The results indicated that recall was comparable to the coverage rates provided indicated by the antenatal care cards. These findings suggest that intermittent preventive treatment coverage rates reported by large household surveys performed using recalled data are valid.The risk of coronavirus disease 2019 (COVID-19) and dengue coinfection is increased in tropical countries; however, the extrapulmonary clinical manifestations have not been fully characterized. We report a 42-year-old woman whose clinical manifestations began with fever, diarrhea, headache, chest pain, myalgia, odynophagia, and arthralgia. Despite mild respiratory symptoms and normal chest computed tomography scan results, she was diagnosed with real-time reverse-transcription polymerase chain reaction (RT-PCR)-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Because she had erythema and petechiae with a decreased platelet count, the dengue NS1 antigen and anti-dengue IgM/IgG test were performed, and the Centers for Disease Control and Prevention RT-PCR assay detected the dengue virus serotype 1 infection. Additionally, increased liver enzyme serum levels were found in the patient, who later developed hepatomegaly. Hence, the mechanism of hepatic pathology associated with SARS-CoV-2 and dengue coinfection needs further research.Global health partnerships (GHPs) have encountered many challenges during the coronavirus disease 2019 (COVID-19) pandemic. New perspectives and insights are needed to guide GHPs when navigating current and future collaborations. This study aimed to understand perspectives and insights of international partners regarding how the COVID-19 pandemic impacted their GHPs with institutions in the United States. We performed a cross-sectional qualitative study conducted through virtual semi-structured interviews performed between June 12, 2020 and July 22, 2020. We queried academic institutions based in the United States to refer individuals from their corresponding international GHP organizations. We invited these individuals to participate in virtual interviews that were audio-recorded and transcribed. We analyzed data qualitatively to identify themes. Eighty-four United States partners provided e-mail addresses for international partners. Ten individuals from these GHPs completed the interview. Participants reported overall positive experiences with their United States-based partners during the pandemic. The following themes emerged imbalanced decision-making; worry about partnership continuity; opportunity to optimize communication within partnerships; interest in incorporating technology to facilitate engagement; and a desire for increased bilateral exchanges. Several challenges appeared to exist before COVID-19 and were highlighted by the pandemic. Most respondents were optimistic regarding the future of their GHPs. However, concerns were expressed regarding the implications of fewer in-person international experiences with United States trainees and the desire for stronger communication. Although our results do not represent the perspectives and insights of all GHPs, they provide considerations for the future. We urge institutions in the United States to re-examine and strive for equitable relationships with their international partners.Globally malaria incidence has declined, but further reductions in malaria are not evident in many countries. In addition to the public health approaches for tackling malaria, involvement of the private sector is vital because the private sector plays a central role in healthcare delivery to the masses. In India, malaria management is primarily provided through government programs. Nonetheless, significant numbers of fever patients continue to seek healthcare in the private sector. The private sector in India is comprised of formal healthcare (qualified and approved), informal healthcare (unqualified, untrained), and traditional healers. Commercial channels for the procurement of quality-assured malaria diagnostics like rapid diagnostic tests via pharmacies or other approved outlets would empower Indian populations to self-detect malaria without delay. Easier access would minimize the diagnostic time gap, reduce costs to the patient, prevent inappropriate malaria treatment, and foster timely treatment of both malaria and non-malaria infections. Commercially available rapid diagnostic tests in the hands of the people could be an important tool in our fight against malaria.Antibody tests can be tools for detecting current or past severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 [coronavirus disease 2019 (COVID-19)]) infections. link2 Independent test evaluations are needed to document the performance with different sample sets. We evaluated six lateral flow assays (LFAs) and two laboratory-based tests (EUROIMMUN-SARS-CoV-2 ELISA and Abbott-Architect-SARS-CoV-2-IgG). We tested 210 plasma samples from 89 patients diagnosed with acute COVID-19. These samples were collected at different time points after the onset of symptoms. In addition, 80 convalescent plasma samples, and 168 pre-pandemic samples collected from adults in the United States and in Africa were tested. LFA performance varied widely, and some tests with high sensitivity had low specificity. LFA sensitivities were low (18.8-40.6%) for samples collected 0 to 3 days after symptom onset, and were greater (80.3-96.4%) for samples collected > 14 days after symptom onset. These results are similar to those obtained by ELISA (15.6% and 89.1%) and chemiluminescent microparticle assay (21.4% and 93.1%). The range of test specificity was between 82.7% and 97%. The combined use of two LFAs can increase specificity to more than 99% without a major loss of sensitivity. Because of suboptimal sensitivity with early COVID-19 samples and background reactivity with some pre-pandemic samples, none of the evaluated tests alone is reliable enough for definitive diagnosis of COVID-19 infection. However, antibody testing may be useful for assessing the status of the epidemic or vaccination campaign. link3 Some of the LFAs had sensitivities and specificities that were comparable to those of more expensive laboratory tests, and these may be useful for seroprevalence surveys in resource-limited settings.As the fight against the coronavirus disease 2019 (COVID-19) pandemic continues, the necessity for wide-scale, global vaccine rollout to reduce the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and slow its mutation rate remains unassailable. The COVID-19 Vaccines Global Access (COVAX) initiative's campaign involves a proportional framework to finance and distribute SARS-CoV-2 vaccines in low- and middle-income countries. However, the COVAX framework has critical limitations, including limited funding and the failure to account for the special epidemic risks and needs of its participating nations, as recommended by the World Health Organization's Strategic Advisory Group of Experts on Immunization framework. These drawbacks disproportionately impact Africa, where many nations rely on COVAX as their main source of vaccines. The current plan to vaccinate only up to 20% of participating nations' populations is short-sighted from both epidemiologic and moral perspectives. COVAX must commit to vaccinating all of Africa and its initiative must be modified to account for the health and economic infrastructures in these countries. Lessons learned from successful vaccination campaigns, including the West African Ebola outbreak, have shown that vaccinating all of Africa is possible and feasible, and that infrastructure and human resources can support mass vaccination. To halt this global pandemic, global responsibility must be accepted to finance and equitably distribute SARS-CoV-2 vaccines to African nations. We urge COVAX to act swiftly to prevent Africa from becoming the new face of a persisting pandemic.Antivenoms are the treatment of choice for managing lethal snakebites. However, antivenoms may not be available in instances where non-native vipers are kept in captivity. We report a case of a puff adder (Bitis arietans) bite treated without antivenom. A 23-year-old man was bitten on his left hand by a puff adder that he illegally kept in his house. The swelling spread rapidly to the upper arm and there was a risk of bleeding, suggesting the need for antivenom administration, but this could not be acquired because of lack of stock. We initiated fluid resuscitation and administered recombinant thrombomodulin (rTM) to prevent venom-induced consumption coagulopathy. In addition, hyperbaric oxygen (HBO) treatment was also performed to reduce local swelling. The patient recovered without complications after the multidisciplinary treatment. Further studies are needed to prove the safety and efficacy of rTM administration and HBO therapy as an adjunct or alternative therapy with antiserum for fatal snakebite.The study was an attempt to capture Anopheles stephensi from cattle sheds during dawn to understand the realistic density of the resting mosquitoes. A 2-year longitudinal study was carried out in cattle sheds in close proximity to the human dwellings to collect the resting vector mosquitoes. The man-hour density of A. stephensi ranged from 24.7 to 206.5. The vector incrimination results indicated 0.15% of A. stephensi infected with Pv210 in 2015 and 0.09% in 2016. The current study has revealed that cattle sheds are the preferred resting place of A. stephensi and that dawn is the perfect time to collect and estimate its densities. Hence, adult vector control may also be given due importance in addition to the routine larval source management measures to curb malaria transmission in an urban setting.
