World Health Organization, The study reviews the available scientific evidence regarding the effectiveness of syndromic screening to stop or slow the spread of COVID-19 at land borders.
Syndromic Screening For COVID-19: The World Health Organization (WHO) stated in a scientific brief that there is not enough data to deploy COVID-19 testing for severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) transmission prevention across land borders.
Overview
According To WHO, Some nations have been conducting syndromic screening of travellers who cross land borders in light of the COVID-19 pandemic. In addition to monitoring and the submission of health declaration forms, methods include checking for fever and respiratory or other symptoms. Communities that are near to land borders are frequently extremely connected by economic, social, and familial relationships, and many travellers cross land borders every day or more. The evaluation of any intervention employed to stop the spread of COVID-19 is complicated by the issue of unauthorised ground crossings and permeable borders.
Background
Over 651 million cases and 6.6 million fatalities have been reported globally since the COVID-19 epidemic began. Due to inadequate testing and infection data from all across the world, the cumulative infection and death rates linked to the COVID-19 pandemic are likely underestimated.
In order to better understand the SARS-CoV-2 virus, safeguard populations from outbreaks, and create reliable diagnostic tests to address these issues, researchers, health officials, and diagnostic businesses have teamed up globally. Syndromic testing is crucial in the fight against the pandemic, but diagnostic tests for SARS-CoV-2 are currently being developed.
What Is Syndromic Testing?
Syndromic testing is the use of a single test to diagnose numerous pathogens with similar indications and symptoms. This may involve keeping an eye on the patient, filling out health statement forms, and getting their temperature and other concerns tested. Syndromic testing was used for various communicable diseases like the plague, pandemic H1N1, and the Ebola virus disease prior to the COVID-19 outbreak.
Effectiveness of syndromic testing
The effectiveness of syndromic testing in reducing traveller COVID-19 transmission has come under scrutiny. Additionally, any effort to stop the spread of COVID-19 and other infectious diseases is hampered by illegal land incursions and open borders, especially in times of national or international crises.
The usefulness of syndromic testing in preventing the spread of COVID-19 at border crossings and transboundary river crossings was evaluated by the authors of this scientific brief. This study used the PICO question to investigate the impact of COVID-19 syndromic departure and entry screening of travellers crossing land borders (Population, Intervention, Comparison, Outcome).
The study
To answer the PICO question, a thorough review was done. The GRADE technique (Grading of Recommendations, Assessment, Development, and Evaluation) was used to grade the quality of the evidence, which was categorised as high, moderate, low, or severely low.
Using the Newcastle-Ottawa Scale, an outside systematic review team evaluated the validity of the research (NOS). The WHO International Travel and Health Guidelines Development Group examined data and made conclusions (ITH GDG). The study discovered seven empirical papers that looked at the effectiveness of COVID-19 screening at border crossings that were published between January 2020 and 2020.
The efficiency of syndromic screening records obtained from 7,181 truck drivers who entered Uganda through Mutukula from 15 May to 30 July 2020, in the United Republic of Tanzania, was investigated in a retrospective cross-sectional study in Uganda.
Syndromic Screening For COVID-19
Findings
Thermal screening was unsuccessful in identifying COVID-19 infections during border crossings in a cross-sectional retrospective investigation carried out in Uganda. Over the course of the seven studies, the tests found considerably different numbers of instances, ranging from 2.2% to 43.6%. There was not enough evidence to prove or disprove the assertion that syndromic screening entails health concerns. As a result, the WHO came to the conclusion that there is not enough evidence to support COVID-19 syndromic testing at border crossings.
Additionally, using unofficial and informal border crossings to avoid checks can make it more difficult to assess the success of the intervention. It should be noted that some nations may not benefit from syndromic testing due to the present spread of SARS-CoV-2 mutations. Additionally, screening could mislead locals and visitors into feeling secure.
It was also mentioned that effective coordination among the participating nations and cross-national communication are crucial for correctly interpreting and employing screening procedures. Syndromic screening may negatively impact a person’s ability to access healthcare professionals and carers if they have a disability.
Additionally, studies comparing the effectiveness and success of syndromic screening in comparison to testing, quarantine, and other public health and social interventions, as well as syndromic screening when combined with other health measures, are urgently needed.
Limitations
There are a number of restrictions in this summary, including the few research (just seven investigations), early pandemic investigations, data stratification, and a lack of scientific expertise. Due to these restrictions, active surveillance in the future and study methods that distinguish the impacts of syndromic screening procedures are required.
