COVID-19 Pandemic Causes Increased Clinic Visits with Diagnosis of Tegumentary Leishmaniasis in Brazil in 2020
SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), a highly pathogenic β-coronavirus (family Coronaviridae) is the etiologic agent of COVID-19 (Coronavirus Disease 2019), the disease that gave rise to a difficult to control pandemic, especially in Brazil (Candido et al., 2020). Due to the lack of vaccines and drugs to contain the disease and given the high transmissibility of the virus through aerosols and droplets, it became consensual in several countries around the world to take respiratory etiquette measures to reduce interactions between people and reduce the risks of transmission and slow the progression of the pandemic (Szylovec et al., 2020).Serological cross-reactivity using a SARS-CoV-2 ELISA test in acute Zika virus infection, Colombia
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the etiological agent of coronavirus disease-2019 (COVID-19), an emerging zoonotic viral disease responsible for an ongoing pandemic (Chams et al., 2020). The infection has spread globally, with 31,167,374 confirmed cases and 962,046 related deaths as on September 21, 2020 (https://coronavirus.jhu.edu/map.html). Clinically, according to a recent systematic review with meta-analysis, in patients with COVID-19, fever was the most prevalent clinical manifestations (88.7%, 95% CI 84.5–92.9%), followed by respiratory symptoms such as cough and dyspnea, which could be present in less than 60% of the patients (Rodriguez-Morales et al., 2020).Sensitivity of different RT-qPCR solutions for SARS-CoV-2 detection
The ongoing pandemic of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causing the coronavirus disease 2019 (COVID-19) has imposed an increasing demand on daily diagnostic screening. This is expected to perpetuate over the coming months, due to the recurrence of outbreaks and lifting of lockdown measures worldwide (Patel et al., 2020). Given the high sensitivity compared to serological testing (Cassaniti et al., 2020), standard diagnosis continues to rely on RNA extractions from respiratory or oral samples followed by one-step reverse transcription and real-time quantitative polymerase chain reaction (RT-qPCR) that entails one or several primer-probe sets for targeting SARS-CoV-2 sequences (Corman et al., 2020).Ascertainment rate of novel coronavirus disease (COVID-19) in Japan
As of March 1, 2020, a total of 58 countries had reported at least one confirmed case of novel coronavirus disease (COVID-19), and the cumulative number of deaths had reached 2977 persons across the world (WHO, 2020). To achieve appropriate countermeasures, it is vital to understand the current epidemiological situations of the COVID-19 epidemic.
