The director of the Center for the Coordination of Health Alerts and Emergencies (CCAES), Fernando Simon, has advocated this Thursday for “reduce indoor activities“, why “closed places are places of risk“.
At the press conference in which he reported on the evolution of the pandemic in Spain, Simón made this recommendation when asked about the inclusion of scientific evidence that points to aerosols as a route of transmission in the scientific information document -Technique of disease by coronavirus, the Covid-19.
Now there is “much more consensus” on the fact that “inhalable and infective particles can remain in the air for a greater or longer distance” than when talking about transmission by droplets, and “it has become increasingly clear that closed spaces are places of risk”, has pointed.
The director of the CCAES has explained that the risk can be reduced above all through natural cross ventilation, which renews the air, or with “good” ventilation systems, while other mechanisms, such as filters, “can help to some extent”. However, “the ideal” is to reduce indoor activities and continue to maintain distance and use of masks.
On transmission in nursing homes, has admitted that the data “they had to surface” “sooner or later” after the peak of the second wave, since “the entry” of the virus cannot be 100% prevented, which reaches these centers through the exits and entrances of the residents, relatives or workers.
“Numerically, they are a significant number, but the proportional impact is much less than in the first wave,” Simón pointed out, alluding to the fact that there are more resources to work both in residences and hospitals, so the transmission is ” somewhat less “, while hospitals are” somewhat less overburdened “and allow” more effective “treatments.
If the fatality of Covid-19 in patients over 80 years old was 22% in the first wave, now it is around 8%. In the first wave, the impact was “huge”.
Among the changes in these centers with respect to the start of the pandemic, Simón has also cited the best surveillance systems, with centers that carry out periodic screenings to detect “infected” who do not have symptoms.
Furthermore, it has confirmed that the incidence of influenza is “lower” than in other years, although there is no “certainty” of the reasonWell, “there remains the doubt” whether it is due to the effect of the use of masks and to the distance, or to a surveillance system “a little affected”, because the resources are devoted to the coronavirus.
The head of the CCAES has indicated that the influenza surveillance system is going to be improved so that “soon” it works like previous years.
