Coronavirus – All news: Intense concern over the course of cases in northern Greece, showed Talking to Newsbomb.gr the president of the doctors of the hospital of Athens – Piraeus, Matina Pagoni.
The numbers reflected in the reduction of daily cases are not what they expected, the fact that in the last 24 hours there has been a slight decrease in the number cases, does not mean at this stage anything characteristically prominent in Newsbomb.gr the president of the doctors of the hospital of Athens – Piraeus, Matina Pagoni.
“We have a very high viral load, so the numbers of cases are not what we expected.” mentioned features.
Ms Pagoni also added that Attica is in a better situation than Thessaloniki. Indeed, he expressed great concern about co-equity, as a return to normalcy appears uncertain.
“Today’s announcements of the Thessaloniki posts are disgusting, the viral load is still very high. It will be too late to get back to normal in northern GreeceMs. Pagoni highlighted.
What does the wastewater reveal?
The interdisciplinary team of the Aristotle University of Thessaloniki, using the data from the measurements it performs for the main European capitals, seeks documented answers to the question of why the situation in Thessaloniki is not improving, as would be expected after the imposition of strict measures restrictive.
A stabilization trend at the very high levels of early November, when Thessaloniki entered the gray zone of the areas of the country with the highest epidemiological burden, with the application of strict restrictive measures, emerges among the latest measurements in the wastewater of the urban complex, in research carried out by an interdisciplinary team. AUTh, in collaboration with EYATH.
In the corresponding diagram, which shows the viral load measurements in the Thessaloniki sewer system since the beginning of the epidemiological outbreak, it is observed that in the last four samplings – from November 25 to December 2 – the downward trend that began to be registered in the four previous measurements, sampling from November 16 to 23.
“Very easily, the trend can increase again exponentially”
“We are particularly concerned about the results of the latest measurements in wastewater, as they show that the improvement in the epidemiological picture has stopped at a dangerous point. Taking into account international experience, based on the wastewater rationalization measures that we do for Brussels, Amsterdam and Paris, we can say that the situation is very marginal for the city, since the tendency to measure the viral load can very easily to rotate again incrementally and even exponentially. And as the starting point this time is high, the situation can get out of control ”, the rector of AUTh and scientific head of the research project, Prof. Nikos Papaioannou, told APE-MPE, explaining the criticality of the data.
“We are at a critical juncture where the reliability of the measurements is crucial. The computational rationalization applied by the AUTh team in the measurements, based on 24 qualitative and quantitative environmental characteristics of the wastewater, increases the precision of the wastewater by an order of magnitude. determination of viral load. This makes our measurements a reliable tool to diagnose the spread of the virus and a valuable aid in decision-making. In these critical hours, the margin of error should be as small as possible “, he explained Professor of Chemistry and member of the interdisciplinary team, Professor Theodoros Karapantsios.
In the attached diagram, published by ΑΠΕ-ΜΠΕ, the sampling days, recorded in red, correspond to more than 500 cases – as announced on the respective days by EODY – the days recorded in orange to 100-400 cases and the days registered in green in less than one hundred cases.
“Why … Thessaloniki got stuck”
The interdisciplinary team of the Aristotle University of Thessaloniki, using the data from the measurements it performs for the main European capitals, seeks documented answers to the question of why the situation in Thessaloniki is not improving, as would be expected after the imposition of strict measures restrictive.
“Very high viral load is the main reason for the slow rates of decline since the measurements were taken.” The higher the viral load, the longer it takes for the measures to work. This is clear and it must also be borne in mind that the measures implemented since November were not, from the beginning, similar to those of last spring. It is also evident in the traffic on the streets, a greater relaxation of the citizens, compared to last April, which is explained by the fatigue that has occurred, but is by no means justified, at a time when there is suffocating pressure in the city’s hospitals. and how serious the situation is now can be realized by each one of us, who surely already knows someone who became ill, someone who died from complications of the virus “, said the rector of the AUTh, giving an interpretation of the epidemiological picture of the city.
In addition, he set some more parameters: “When it was decided to suspend most of the activities and all the family members were locked up in their homes, this generated new outbreaks, since there were already too many asymptomatic carriers in the community and new ones were created in the same area. Infections In addition, another problem that may not have been adequately addressed relates to areas of possible excessive transmission of the virus and mainly to buses and public markets. Perhaps more measures can be taken there, there are solutions that have been successfully implemented in other European cities, solutions that we could implement immediately, such as the temporary inclusion of tourist buses in the OASTH fleet for the safe movement of citizens, such as the greater “Distribute the stalls in popular markets, etc.”, stressed the rector.
“The measurements are correct but they are not fulfilled correctly”
“The assessment confirmed by the tests on the samples that we receive in the Hospital and Structures Laboratory through EODY, is that there is a stabilization of cases at high levels, there is no reduction that we expected and this may be due to non-strict compliance with the measurements”. , is the interpretation given to the epidemiological picture of Thessaloniki by the director of the 1st Microbiology Laboratory of the Aristotle University of Thessaloniki and member of the Expert Committee of the Ministry of Health, Professor Anna Papa Konidari. “If we were all more consistent, if we followed the measures with more reverence, the outlook would be better,” Papa told APE-MPE.
When asked if this finding leads to discussions in the Expert Committee on the possible need for stricter measures, the professor replied: “The measures are correct, you just have to follow them correctly. More effort is required. If the measures did not work , the increase in cases would be exponential, the spread would be such that hospitals would not be able to function. However, stability is not enough for us, what we want is a drop in the indicators, which means even more strict compliance with the measures ” .
In this context, Ms Papa explained that “with the Intensive Care Units full, the discussion on the lifting of restrictive measures in Thessaloniki is premature, the situation remains difficult and every day in the Committee all the data is discussed epidemiological “.
“We closed the door of the house to the coronavirus when it had already entered the rooms”
“The de-escalation of the epidemic in Thessaloniki is very slow because the so-called blockade was imposed quite late, when there was already a great spread of the virus in the city”, is the assessment of the professor of Pulmonology of the AUTh and Director of the Respiratory Clinic at Papanikolaou Hospital, Giannis Kioumis.
“A popular opinion of the lockdown is that we actually lock our houses assuming we keep the coronavirus out. If the lockdown is delayed, when we close the front door of the house it is already very likely that the coronavirus is inside the rooms, which it means that an epidemic cycle has started within the family itself. This is reflected in the cases and, of course, in the sewage, “Mr. Kioumis told APE-MPE.
“When the restrictive measures were implemented, the virus was already present in many homes, it had spread to an epidemic wave, where we saw in clinical practice that members of the same family were infected. Thus, in the sewerage it is expected that the viral load will decrease, when it has exhausted its cycle within families ”, explained the professor.
He added that “a second explanation – not an alternative, but added to the previous one – is that there are a large number of asymptomatic patients in the community, at a rate that we do not know,” since there are international studies that can be from 3 to 10. The number real number of carriers is many times higher than those diagnosed ”, therefore“ it is not possible to know this and therefore the sampling for the diagnosis of coronavirus must be properly stratified, there must be a representative sample of all social groups, spatial areas, professional activities “, because” if the sample is those who go to hospitals and private laboratories to perform tests, it is not representative. “
