La nostra maschera antinfluenzale e il coronavirus ci proteggono?

Indossare una maschera medica è una delle misure preventive intese a limitare la trasmissione di infezioni respiratorie, inclusa l'infezione causata dal nuovo coronavirus (COVID-19) in Cina. Tuttavia, indossare una maschera non è sufficiente, quindi è necessario prendere altre misure, tra cui le più importanti sono il rispetto delle norme igieniche.

Cos'è una maschera medica?
Una maschera medica è uno strumento utilizzato per prevenire la trasmissione di infezioni. Copre il naso e la bocca e ha anelli che sono fissati dalle orecchie. Le maschere per il viso aiutano a limitare la diffusione dei germi. Quando qualcuno parla, tossisce o starnutisce, piccole gocce di agenti patogeni vengono rilasciate nell'aria che può infettare le persone circostanti. Indossando una maschera, puoi prevenire la contaminazione di altre persone.

Ma indossare una maschera medica è solo una delle misure per prevenire le infezioni respiratorie. A questo proposito, le misure di igiene personale sono importanti. Lavati spesso le mani con acqua e sapone, copri la bocca quando starnutisci, tossisci o ti pulisci il naso, lavati sempre le mani prima di preparare il cibo, prima di sederti al tavolo e dopo essere andato in bagno.

Chi dovrebbe indossare una maschera medica?
Si consiglia di indossare una maschera medica:

Le persone con sintomi di infezioni respiratorie
Le persone che si prendono cura di pazienti con infezioni respiratorie
Coloro che sono stati in contatto con pazienti con altre infezioni respiratorie
Coloro che visitano ospedali o cliniche
Personale medico
Personale dell'industria alimentare
Autisti o autisti di trasporto pubblico
Persone che lavorano in luoghi incustoditi o insufficientemente ventilati
Studenti e insegnanti (tranne le lezioni di educazione fisica).
È consigliabile indossare una maschera per proteggersi dal coronavirus?
Considerate le preoccupazioni per il nuovo coronavirus in Cina, molte persone si chiedono quale sia il modo migliore per proteggersi dalle infezioni. E molti si chiedono se una maschera medica offra protezione e, in caso affermativo, che tipo di maschera? La cosa più importante da ricordare è che gli specialisti stanno cercando di capire come viene trasmesso il nuovo coronavirus. Il Centro statunitense per la prevenzione e il controllo delle malattie (CDC) raccomanda:

Lavarsi le mani frequentemente durante il giorno;
Evitare di toccare gli occhi, il naso e la bocca a mani nude;
Evitare il contatto con persone malate.
Queste misure aiutano a prevenire molte infezioni, comprese quelle con il nuovo coronavirus.

Le raccomandazioni delle organizzazioni internazionali per le persone che sono sospettate di avere un'infezione con il nuovo coronavirus e che hanno lievi sintomi respiratori dovrebbero:

Lavarsi spesso le mani con acqua e sapone o disinfettare le mani con una soluzione a base di alcol
Mantenere la distanza da persone sane almeno 1 metro
Indossare una maschera medica.
I caregiver di coloro che sono sospettati di essere infettati dal nuovo coronavirus devono seguire le stesse misure e, inoltre, devono smaltire il materiale contaminato con le secrezioni del paziente nel modo più sicuro possibile e aprire le finestre il più spesso possibile.

Questa maschera facciale può svolgere un ruolo nella prevenzione delle infezioni, ma questo ruolo è limitato nelle situazioni reali. Ci sono prove che la maschera ti protegge dalla trasmissione del virus di mano in bocca, probabilmente perché stai più attento a non toccare il viso quando lo indossi. Sei anche più protetto dalle cadute quando qualcuno starnutisce o tossisce vicino a te.

La più grande preoccupazione che i medici nutrono per queste maschere è il falso senso di sicurezza che ti dà il loro abbigliamento. Ci sono molte ragioni per cui le maschere non sono l'ideale. Ad esempio, è difficile trovarne uno che si adatti perfettamente al naso e alla bocca e mantenerlo a lungo. Nel momento in cui tocchi il naso o la bocca quando indossi una maschera, il suo ruolo protettivo si perde. In ambiente medico, ci sono chiare raccomandazioni su quando indossare la maschera e su quale protezione è indicata in base al tipo di infezione dei pazienti.

Precauzioni relative alle gocce di saliva: utilizzare una maschera medica rettangolare in caso di infezione che si diffonde attraverso grandi gocce quando qualcuno tossisce, starnutisce o parla. Infezioni come l'influenza, la pertosse e alcuni tipi di meningite batterica rientrano in questa categoria. Sia la persona infetta che gli altri dovrebbero indossare maschere per il viso. È molto importante che i caregiver indossino una maschera ogni volta che interagiscono con il paziente e ne hanno una nuova ogni volta che entrano in contatto con il paziente.

Does our flu mask and coronavirus protect us?

Wearing a medical mask is one of the preventive measures meant to limit the transmission of respiratory infections, including infection caused by the new coronavirus (COVID-19) in China. However, just wearing a mask is not enough, so it is necessary to take other measures, among which the most important ones are to respect the hygiene norms.

What is a medical mask?
A medical mask is a tool used to prevent the transmission of infections. It covers the nose and mouth and has loops that are fastened by the ears. Face masks help to limit the spread of germs. When someone speaks, coughs or sneezes, small drops of pathogens are released into the air that can infect the surrounding people. By wearing a mask, you can prevent contamination of other people.

But wearing a medical mask is just one of the measures to prevent respiratory infections. In this regard, personal hygiene measures are important. Wash your hands frequently with soap and water, cover your mouth when sneezing, coughing or wiping your nose, always wash your hands before preparing food, before sitting down at the table and after going to the toilet.

Who should wear a medical mask?
Wearing a medical mask is recommended:

People with symptoms of respiratory infections
People who care for patients with respiratory infections
Those who have been in contact with patients with other respiratory infections
Those who visit hospitals or clinics
Medical staff
Food industry personnel
Drivers or drivers of public transportation
Persons working in unattended or insufficiently ventilated places
Students and teachers (except physical education classes).
Is it advisable to wear a mask to protect yourself from coronavirus?
Given concerns about the new coronavirus in China, many people wonder what is the best way to protect against infection. And many wonder if a medical mask offers protection, and if so, what kind of mask? The most important thing to remember is that the specialists are trying to understand how the new coronavirus is transmitted. The US Center for Disease Prevention and Control (CDC) recommends:

Hand washing frequently throughout the day;
Avoid touching the eyes, nose and mouth with bare hands;
Avoid contact with sick people.
These measures help prevent many infections, including those with the new coronavirus.

Recommendations from international organizations for people who are suspected of having infection with the new coronavirus and who have mild respiratory symptoms should:

Wash your hands frequently with soap and water or disinfect your hands with alcohol-based solution
Keep distance from healthy people at least 1 meter
To wear a medical mask.
Caregivers of those suspected of being infected with the new coronavirus should follow the same measures and, moreover, need to dispose of contaminated material with the patient's secretions as safely as possible and open the windows as often as possible.

This face mask may play a role in preventing infection, but this role is limited in real situations. There is some evidence that the mask protects you from transmitting the virus from hand to mouth, probably because you are more careful not to touch the face when wearing it. You are also more protected from drops when someone sneezes or coughs near you.

The biggest concern that doctors have about these masks is the false sense of security that their wearing gives you. There are many reasons why face masks are not ideal. For example, it is hard to find one that will fit perfectly around the nose and mouth and keep it for a long time. The moment you touch your nose or mouth when wearing a mask, its protective role is lost. In the medical environment, there are clear recommendations regarding when to wear the mask and what protection is indicated depending on the type of infection the patients have.

Precautions related to saliva drops: Use a rectangular medical mask in case of an infection that spreads through large drops when someone coughs, sneezes or speaks. Infections such as influenza, pertussis and certain types of bacterial meningitis fall into this category. Both the infected person and others should wear face masks. It is very important that the caregivers wear a mask every time they interact with the patient and have a new one every time they come in contact with the patient.
