According to the National Test Strategy for SARS-CoV-2, tests for covid-19 are carried out every 14 days in schools, prisons, factories and in construction in the communities with a high fall frequency.
According to the strategy update from the General Directorate of Health (DGS), which came into force on Monday, communities with a cumulative incidence of Covid 19 to 14-day cases of more than 480 per 100,000 inhabitants are affected.
In these regions rapid antigen tests (TRAg) with a frequency of 14/14 days are used in “occupational contexts with high social exposure” such as factories, construction, schools, etc.
“If no cases of SARS-CoV-2 infection are identified: The screening periodicity is retained,” emphasizes the DGS standard, which comes into force on Monday, oh.
In a cluster and outbreak situation, such as in schools, educational institutions, residential structures for the elderly (ERPI) and similar / closed facilities, a rapid antigen test should preferably be carried out on all high and low level contacts with low risk under the coordination of teams public health in cooperation with municipal partners or other institutions.
According to DGS, it must be possible to adapt the now revised strategy to the epidemiological situation at regional and local level as well as to the available resources in order to reduce and control the transmission of data through the “appropriate use of laboratory tests”, and prevent and mitigate their effects on health services and populations at risk and monitor the epidemiological evolution of Covid-19.
The standard extends testing for SARS-CoV-2 to all contacts, including performing low-risk molecular testing “at the time of identification” of the contact.
Antigen tests are available in Health Center Groups (ACES) and Local Health Units (ULS) to control community transmission and monitor epidemiological evolution of Covid-19.
Rapid antigen tests are also provided with personal advice to asymptomatic users who agree with their performance.
“In urgent and emerging proceedings, the lack of a laboratory test must not delay the provision of adequate clinical care, and in these circumstances the appropriate personal protective equipment (PPE) must be used by health professionals to care for patients suspected of having COVID -19 “, emphasizes the DGS.
Laboratory tests to screen for SARS-CoV-2 infections should be performed in health units.
According to the strategy, laboratory tests should be prescribed and interpreted through diagnosis and screening according to a clinical and health purpose.
Diagnosis with the identification of the infection in symptomatic persons suspected of having Covid-19 and in asymptomatic persons in contact with a confirmed case and screening with detection of the infection in asymptomatic persons and without contact with a confirmed case of covid-19 refers to the standard that updates the standard published on October 29, 2020.
DGS says that “given the current stage of the Covid-19 pandemic, it is important to strengthen lines of intervention based on epidemiological developments and the advancement of scientific knowledge”.
According to the Fall-Winter 2020-21 Health Plan, “the ability to control the epidemic through effective contact screening, the use of large-scale laboratory diagnostic tests for SARS-CoV-2, active detection and early case management; and strict isolation of cases and their contacts are key elements in limiting the spread of covid-19. “
