Although its sensitivity when LAMP is used is lower than reverse-transcriptase polymerase chain reaction, this procedure can contribute to COVID-19 control by detecting individuals able to transmit the disease.

This report highlights the importance of an adequate sample treatment for saliva to detect SARS-CoV-2 and describes a flexible procedure that can be adapted to point-of-care. Although its sensitivity when LAMP is used is lower than reverse-transcriptase polymerase chain reaction, this procedure can contribute to COVID-19 control by detecting individuals able to transmit the disease.

Antimicrobial IgG avidity is measured in diagnosis of infectious disease, for dating of primary infection or immunization. Navitoclax mouse It is generally determined by either of two approaches, termed here Avidity Index (AI) or End-Point-Ratio (EPR), which differ in complexity and workload. While several variants of these approaches have been introduced, little comparative information exists on their clinical utility.

Here, we systematically compared their performances and designed a new sensitive and specific calculation method, for facile implementation in the laboratory. We compared the avidities obtained by AI, EPR, as well as the newly developed approach, across parvovirus B19, cytomegalovirus, Toxoplasma gondii, rubella and Epstein-Barr virus panels comprising 460 sera from individuals with recent primary infection or long-term immunity.

With optimal IgG concentrations, all approaches performed equally, appropriately discriminating primary infections from past immunity (ROC-AUC 0.93-0.94). However, at lower IgG concentrations the avidity status (low, borderline, high) changed in 17 % of samples using AI (AUC 0.88), as opposed to 4 % using EPR (AUC 0.91) or 6 % using the new method (AUC 0.93).

The new method measures IgG avidity accurately, in a broad range of IgG levels, while the popular AI approach calls for sufficiently high antibody concentration.

This study aimed to investigate an outbreak of a non-malaria, undifferentiated febrile illness, among internally displaced persons (IDPs) living in humanitarian camps in North Darfur, Sudan, in 2019.

An investigation team was deployed to North Darfur to identify suspected cases and collect blood samples, and clinical and demographical data. Blood samples were examined microscopically for Plasmodium spp and tested for dengue (DENV) and yellow fever viruses by reverse transcriptase-quantitative polymerase chain reaction.

Between September 7 and December 18, 2019, we clinically identified 18 (24%), 41 (54%), and 17 (22%) cases of dengue fever, dengue with warning signs, and severe dengue, respectively. Blood samples were collected from 22% of patients, and 47% of these tested positive for DENV-1 RNA. We confirmed 32 malaria cases with 5 co-infections with DENV. This outbreak of dengue was the first among IDPs in the humanitarian camps.

Our findings indicate that dengue has become endemic or that there has been a new introduction. Further epidemiological, entomological, and phylogenetic studies are needed to understand disease transmission in the area. An early warning and response system and an effective health policy are crucial for preventing and controlling arboviruses in Sudan.

To analyze the relationship between traffic inflow and COVID-19 prevalence in South Korea for formulating prevention policies for novel infections.

We evaluated traffic inflow and new COVID-19 cases in 8 regions of Korea from January 1, 2020, to January 31, 2021. The toll collection system (TCS) traffic volume for 2019-2020 and traffic inflow trends were analyzed using independent samples t-test and nonlinear regression, respectively. The association between TCS traffic volume and new COVID-19 cases by city was analyzed using correlation analysis.

Traffic inflow volume in 2020 decreased 3.7% from 2019. The TCS traffic inflow trend in the 8 provinces decreased during the first COVID-19 wave, gradually increased until the second wave, decreased after the second wave, and showed a sharp decrease in the third wave. There was a positive correlation between the traffic inflow volume and new cases in Busan-Gyeongnam and Jeonbuk, but not in Daegu-Gyeongbuk or Gangwon.

A decrease in new COVID-19 cases in the regions was associated with increased traffic inflow volume. Therefore, the Korean government can establish preventive social distancing policies by identifying increases or decreases in traffic volume. These policies will also need to consider the distribution of vaccines in each area.

This study introduces a case of MIS-A, where the patient presented 3 weeks after initial COVID-19 exposure. His clinical course was consistent with the working definition of MIS-A as specified by the CDC. Aggressive supportive care in the intensive care unit, utilization of advanced heart failure devices, and immunomodulatory therapeutics (high-dose steroids, anakinra, intravenous immunoglobulin) led to clinical recovery. Management of MIS-A is a topic of ongoing research and needs more studies to elaborate on treatment modalities and clinical predictors.
