With the acceleration of the vaccination campaign against the SARS-CoV-2 coronavirus and the arrival of summer, some anti-infective measures have been relaxed, such as the obligation to wear masks outdoors, which are gradually relaxing. Until then, if there is no personal protective equipment, it will be safe.
Since last fall Italy Obliged to wear mask also Outdoor activitiesBut with Vaccination campaign Against this Coronavirus disease This measure may be withdrawn soon. Pierpaolo Sileri, Deputy Minister of Health Recently announced When I 30 million vaccinated, At least with First dose. At present, according to the “Vaccination Chart” in “Data World”, in my country, a total of 25.9 million doses of vaccine have been injected, of which 8.08 million received full immunization, accounting for 13.4% of the national population.In spite of this, we are still far from the place where we dream of co. Herd immunity -Some scholars believe that in fact this is a goal we may never achieve-to reach the limit pointed out by Dr. Sileri, it may only take a few weeks.After all, hundreds of thousands of doses are administered every day, and the new benign goals pointed out by General Emergency Specialist Francesco Figliuolo plan to achieve As of June, one million doses.In areas where the competent authority travels faster, it has already been mentioned Outdoor mask They may become memories; in LazioFor example, more than 2.5 million people have been vaccinated, It can be withdrawn in JulyAs the regional health commissioner Alessio D’Amato said in an interview with Messaggero.
inside United States This New standard Centers for Disease Control and Prevention(CDC) Not only do people who are fully vaccinated don’t need to wear masks anymore shut down), but they may also disrespect spacing From others. In practice, they can resume their behavior as they did before the COVID-19 pandemic. Anyone who is fully vaccinated can participate in indoor or outdoor activities, regardless of size, without wearing a mask or maintaining physical distance.If you are fully vaccinated, you can start doing what you stopped doing because of the pandemic,” the new director of the CDC said at a press conference Rochelle Walensky. This is the third relaxation of masks in the United States since the start of the vaccination campaign. In March, the Centers for Disease Control and Prevention (CDC) stated that vaccinated people can gather at home without wearing masks, and soon afterwards the ban on using masks outdoors was lifted. in short, vaccine Representing the broad road of relaxation measures Personal protective equipment We have known since the beginning Pandemic. After all, a recent study by the Centers for Disease Control and Prevention (CDC) showed that Pfizer E Modern They can break down the infection by 90% after the second injection and 80% after the first injection.
An extremely valuable help will also come from Beautiful season; As we all know, in fact, at the most comfortable temperature cycle withaggression God Respiratory virus It has been greatly reduced due to the following reasons.Except in a short period of time, we spent indoors hot Which makes Breath droplets (Water droplets E aerosol) Contains virus particles, which can also trigger several Physiological condition This makes it easier for our body to respond to any virus invasion.Taking a cold as an example, they determined Angionectin, Mucosal irritation And reduce Movement of the eyelashes The upper respiratory tract prescribed by pediatrician Valentina Paolucci; these are conditions that put us at greater risk of infection, so in spring and summer, the risk of infection is much lower.
But, of course, good weather alone is not enough to completely contain infectious viruses such as SARS-CoV-2. From popular countries (e.g.India with Brazil.More importantly, if one considers the emerging variants in circulation: as Dr. Corrado Spinella, head of the Department of Physical Science and Technology of CNR (Cnr-Dsftm), recently announced, new strains-especially English variant -It is required to increase the physical distance between each other by 40 cm, thus increasing from 1 meter to 1.40 meters.Technically speaking, based on the findings of several people education, Even if you don’t wear a mask, this distance may not be enough to protect us. the study”About the transmission of coughs and droplets in the air to humans“For example, a Cypriot scientist from the University of Nicosia published an article in Fluid Physics that determined that respiratory droplets (droplets and aerosols) can reach 6 meters It shoots out from the source with a small wind of 4 to 15 kilometers per hour. I learn”Violent exhalation events: when coughing and sneezingA paper published by the Massachusetts Institute of Technology (MIT) in the Journal of Fluid Mechanics found that coughing and sneezing can eject droplets within 8 meters, further increasing the risk.
Therefore, even outdoors, when the virus spreads at a high speed, masks are also extremely valuable tools if they are killed by masks. Mass vaccination And it can (also) be counted under favorable climatic conditions, so this may be one of the first measures to be cancelled.As Fanpage, a virologist at the University of Milan, said Fabrizio PregliascoIf General Figliuolo conducted a vaccination campaign in Italy and reached 60% of the population receiving the first dose of vaccine by June, the obligation to wear masks outdoors can be cancelled. For indoor places where the risk is naturally higher, virologists recommend waiting more time.
