How Covid-19 cases are counted in Mexico
The National System of Epidemiological Surveillance (SINAVE) is carrying out fieldwork to compare the numbers of COVID-19 in the country. This is a community of doctors and epidemiologists, men and women, from all the states. Patient by patient, they conduct interviews and collect case study information on symptoms, comorbidities, travel history, and contacts.
All of the information that you see presented overnight at the press conference gets released because someone in a community or district health unit was there with a case study and asked the patients for all of this information.
Once they have collected this information, they report it and upload it to an online system of the Sisver (System of Epidemiological Surveillance of Respiratory Disease). A password is entered and, with this database, the cases of COVID-19 are counted.
Through this system, they enter all the information they took from the patient. The moment they click on Submit, the information falls into the federal database. Each of the health care units and jurisdictions has access to this database. It is the states themselves that capture their results.
Through the data on that platform, the federal government extracts the information that the states capture and prepares the slides on COVID-19 that are presented daily. They also use the information to make decisions about the epidemic.
