More than ten days in the past，Fighting the new coronavirus epidemic has become the country’s top priority。This incident originated in Wuhan，Spreading across the country，The epidemic spread to other countries and regions，With the lockdown of Wuhan and other cities in 188bet game、Spring Festival holiday extended across the country，Many communities and transportation facilities、Even outsiders are prohibited from entering public places。After Lantern Festival，Many companies that employ a large number of non-local employees still don’t know what quarantine measures to take，Only so that non-local employees can go to work safely。Currently China’s entire economy is in a state of semi-paralysis，Estimated daily economic losses are as high as 100 billion。If this situation continues for a few more months，Many companies will collapse，The number of unemployed people has risen sharply，The economy will suffer a severe blow，Also threatens social stability。

But at the same time we can also see，In fact, the severity of this epidemic has great regional differences。I analyzed it in my previous article "Looking at the New Crown Pneumonia Epidemic Based on US Influenza Data"，Although the number of confirmed cases and death rates in 188bet game and Wuhan are high，And the epidemic in 188bet game will last for a long time，But the mortality rate outside 188bet game is less than two per thousand (not much different from the mortality rate of influenza in the United States)，And most of them are input types。

Visible，The epidemic outside 188bet game is controllable，There is no need for all parts of the country to adopt closed management measures like 188bet game。We should implement different epidemic prevention measures by region，While epidemic prevention measures cannot be relaxed in 188bet game，We must normalize travel for people outside 188bet game as soon as possible。

In fact, the preventive measures taken by many countries towards this epidemic are divided into regions，For example, Japan only quarantines arrivals who have been to 188bet game in the past 14 days。There are also many cities in China that have adopted a more rational approach of restricting only those who have recently been to 188bet game。But how to identify whether these people have been to 188bet game recently？Currently countries like Japan can only use self-notification，Some areas are worried that someone will conceal the report。Out of this concern，Many places simply restrict all outsiders。If every place adopts this "strictly guard against death" approach，Then the entire economy will be in a state of semi-paralysis，This is unsustainable。So it becomes very important to be able to accurately identify whether someone has been to 188bet game。Those who have not been to 188bet game recently (including those whose household registration is 188bet game，But those who work outside the city) can resume work and travel first。

So how to identify whether a person has been to 188bet game within 14 days?In today’s mobile Internet era，It is not difficult to obtain a list of people who have been to 188bet game within a period of time，Several major telecom operators now have such data，A certain mobile Internet company can cooperate with several major operators，To develop such an App software to determine the list of people who need to restrict travel。Of course，The list of people who have been to epidemic areas and other user privacy data need to be kept confidential，Only used to generate electronic passes and epidemic prevention suggestions。

This anti-epidemic APP，You can authenticate your mobile phone through the telecommunications company’s real name，Compare the list of people who have been to the epidemic area (188bet game) and the list of people in close contact with the patient，Generate a “pass” for travel。The government can respond to changes in the epidemic，Flexibly configure the so-called "high-incidence areas"，Rules for passage (or isolation) and even whether masks are required。The current main epidemic area is 188bet game，In the future, other areas with severe epidemics can be added according to specific circumstances (the unit can be city)，And can be updated in real time，If the epidemic situation in a city in 188bet game Province is greatly alleviated，This city can be excluded from the list of epidemic areas。

After having this APP，It can make the vast majority of people in the country，Can travel to work normally。If you can accurately manage the people traveling，Those who are able to travel are theoretically non-infectious，This way you can avoid panic，You don’t even have to wear a mask (so there won’t be a shortage of masks)。The most important thing is to restore economic order and normal social functioning as soon as possible。And，After having this APP certified，188bet game nationals living abroad will not be restricted from traveling。Overseas countries like Japan can also more effectively distinguish whether someone has recently visited 188bet game。Even for people living in 188bet game,，You can also pass in some designated quarantine areas，After a period of observation，Electronic passes issued by government departments。This App is more than just a temporary pass，It can also be used to publish various official anti-epidemic measures, etc.。In terms of specific implementation，This APP can be developed by professional mobile Internet companies such as Ctrip、Tencent takes the lead，Jointly developed with telecommunications operating companies。

In summary，Facing the epidemic，We need to be prepared to fight the virus for a long time，This requires us to accurately control travel in different regions。There are currently restrictions on going out in some places outside 188bet game、Closing roads and villages are too rough，And the efficiency is very low，Serious negative impact on the economy。If high-tech means can be used to differentiate and control the travel of different groups of people，You can avoid unnecessary travel restrictions and quarantine，Restore normal economic activities in most areas as soon as possible。We need to use existing mobile Internet technology and data to build an anti-epidemic App，To intelligently control and coordinate travel and anti-epidemic work。Of course, private data such as whether you have been to 188bet game，Unless there are extraordinary times like now，Must be strictly prohibited。We also hope that this anti-epidemic APP can complete its historical mission as soon as possible。
