The world unseals and whether the mask continues to wear!

The German government announced on the 6th further "unsealing" plan, many outbreaks of more than 100 people of collective infection, North Rhine-Westphalia has announced the resumption of the blockade measures, and the number of confirmed in two other states is also increasing, may also restart the blockade.

Germany has 16 federal states, each with independent powers to relax restrictions.
All states have agreed to re-impose the blockade if 50 new cases per 100,000 people in seven days, but now three have passed that threshold and are taking a step back.

At first, European and American countries also suggested that citizens do not need to wear masks, but should strengthen personal hygiene habits, such as frequent hand washing, sneezing and coughing with paper towels and then discarded, they are mainly worried that the general public to buy masks will cause front-line medical staff mask slack.

But as the epidemic spread around the world, the public in Europe and the United States have defied government advice to wear masks like Asians, and recently some European and American governments have changed their minds, advising people to wear masks in public.

After the body is infected with the new coronavirus, the virus replicates in the body, is found in the lungs, mouth and nasal fluids, infected people cough ingestors or sneeze, will spray particles containing the virus droplets.

Coughing can produce up to 3,000 droplet particles at a time, and even spit droplets out of the mouth and nose while you're talking. A recent study showed that when we talk about the word "stay healthy", we spit out thousands of droplet particles that are invisible to the naked eye.

Once these droplet particles leave the body, the larger falls on the surface of the object, which can float in the air for hours. Others in the vicinity may become infected if they touch the surface of an object with droplet particles touching their mouth and nose, or may be infected if they breathe directly into the air where droplet particles float.

Ben Cowling, an epidemiologist at the University of Hong Kong, says wearing masks can help reduce community infections, especially in places where public transport and crowds are crowded.

Gobben and his team recently published a study of wearing masks to prevent viral infections, and found that using a general surgical mask can significantly reduce the amount of virus espewing when an infected person breathes and coughs.

After lifting the blockade, Mr. Goben said, there must be a lot of inspection and close tracking of contacts and other supporting measures to ensure that the outbreak does not expand again, health authorities to track the families of infected people and social contacts is easier, but to track who is sitting next to you on the bus or train is not easy.

"This time, if you're wearing a mask, or if everyone on the bus is wearing a mask, you can dramatically reduce the infection rate. "

Another epidemic prevention loophole is that some of the original straps did not show any symptoms before the infection was confirmed, but were already pathogen-borne and contagious, with an estimated 6 to 18 per cent of the population being asymptomatic patients.

The other is the incubation period of infection before the onset of symptoms, 5 days short, 14 days long, even those who are finally infectious patients, before they become ill may have been transmitted to others.

In the above-mentioned epidemic prevention loopholes, wearing masks can effectively prevent the occurrence of these epidemic prevention loopholes.

If enough people wear masks when they go out, the effect of the epidemic prevention on the whole society will also have a great impact.

An unpublished study by scientists at Arizona State University found that even if the mask was generally effective, the death rate in New York could be reduced by 17 to 45 percent within two months as long as 80 percent of people wear it. If the mask sits only 20 percent, New York's death rate could be reduced by 2 to 9 percent if enough people wear it.

In countries with a shortage of masks, some studies have shown that giving older people priority wearing masks can also be a good anti-epidemic effect.

While some people may think that wearing a mask can make the face feel uncomfortable, breathing is not smooth, can not see other people's facial expressions, but as long as you can protect themselves and the people around them safe and healthy, that a small price is what.

Today, wearing a mask is a must on public transport and in shops.
