Does n95 get a virus, does n95 have to be antivirus?

Yes, and there is a high probability, (if you use it to surf the Internet) N95 is a smart phone, it is similar to a computer, have you ever seen a computer that can access the Internet without being poisoned? Hehe, just kidding, but that's the case, you first get an antivirus software suitable for your phone, and remember to update it often in real time, prevention-oriented, don't install unfamiliar software casually, and be cautious about connecting those you don't understand, but don't be too careful, ruin the mood, just use it like a computer.

Why would it be? Did you use the S60 system upstairs? The system60 system used by N95 In fact, the S60 system has very strict control over the software, and the software installation has the right to use 17 and 19 permissions respectively, but it does not involve changing the mobile phone system and changing the data without permission There is no virus at present, let alone installing an antivirus tool. However, the SMS vulnerability of FP1 models (including N95) was recently discovered in Germany, that is, users may suffer from "1234567@**" sent in the form of e-mail. Unprotected and not used for exploit attacks, use to hide) attacks may cause system paralysis Requires a hard grid machine But it can be protected by SMS patches or third-party software So far, there has been no official virus in S60 Most of them are due to the black screen and reboot caused by improper user operation and third-party software development problems.

So it's safe to use the S60!

Yes, smartphones do. No matter what the system.

But the three versions of the machine do a good job in anti-virus. There is one main point that has been overlooked. Press Software to Certificate. But everyone doesn't like certificates and is running away from the problem.

Definitely back! As long as you are careful not to get into that kind of unknown ** and receive inexplicable text messages, you can avoid these! And when connected to the computer, it is best to kill the computer! ~`

Wearing a surgical mask or disposable mask can effectively prevent the virus. However, to wear it correctly, you must completely cover your nose and mouth with a mask and maintain a good airtightness to effectively block the virus infection.

However, medical staff who are directly confronted with patients with infectious diseases must wear N95 masks with a relatively high level of protection. If you use it for 4 hours or if it is contaminated, you should replace it with a new mask in time.

The masks commonly found on the market today can be divided into 3 categories.

That is, a medical surgical mask, which can block 70% of bacteria; or medical protective masks (N95 masks), which can block 95% of bacteria; There are also ordinary cotton masks, which can only block 36% of bacteria.

Experts say that if citizens go to public places without contact with patients, it is enough to wear a surgical mask without excessive protection, but if they can come into contact with patients, they should wear N95 masks.

Some paper masks, activated carbon masks, cotton masks, and sponge masks are not recommended to be used in the current situation because the material is not tight enough, and the effect of preventing bacterial infection is limited.

Academician Zhong Nanshan, head of the senior expert group of the National Health Commission, said in an interview with CCTV News that wearing a mask to prevent the new coronavirus is beneficial, but it is not necessary to wear an N95 mask for prevention, and ordinary medical surgical masks can also prevent most of the viruses stuck to the water droplets from entering the respiratory tract, thereby preventing viral infection.

Standard: It can block 95% of non-oily particles with a diameter of more than microns.

The N95 medical mask is one of the nine anti-particulate masks certified by the National Institute for Occupational Safety and Health in the United States. N95 means that the filtration efficiency reaches 95% under the testing conditions specified by the National Institute for Occupational Safety and Health in the United States, as long as it meets the standards of N95 and passes the standards of such review, it can be called N95 type masks.

The U.S. Occupational Safety and Health Administration (OSHA) has stipulated that medical personnel exposed to highly contagious bacteria and viruses must wear masks with N95 or higher standards.

Difference between KN95 mask and N95 mask:

There is actually no very big or obvious difference between KN95 masks and N95 masks, in fact, only the standards for mask production and testing are different, and the protection level of KN95 and N95 masks is comparable, but they follow the testing standards of different countries.

The KN95 mask follows the Chinese testing standard, and the N95 mask follows the American testing standard, and the protection efficiency of the two against non-oily particles such as experimental sodium chloride particles is not less than 95%. In a certain flow rate range, such as the standard air flow rate range of 85L per minute, the protection efficiency of the diameter particulate matter reaches more than 95%.
