China Using Mobile Apps to Follow Spread of Coronavirus

People in China are using apps on mobile phones to follow and perhaps help slow the spread of the new coronavirus, COVID-19. Some of the apps provide the latest information about areas hit by the virus, while others collect data on infected persons.

The Chinese government is working with two of the country’s largest technology companies to keep track of the disease. The two, Alibaba Group and Tencent Holdings, created color-based systems that record the health of individuals and identify carriers of the coronavirus.

In February, Alipay, a payment app operated by Alibaba, released a system that uses colored QR Codes to show the health of people in the city of Hangzhou. A QR code is a sign a smartphone can read with its camera. Once the sign is recognized, the phone takes the user directly to an internet link with information about a subject.

After completing the questionnaire, users receive a mobile phone message. It includes a color-based QR Code that relates to the health situation they described. Users with a red code are told to quarantine themselves for 14 days and continue reporting their condition by using Alibaba’s DingTalk messaging app. Users with a yellow code are told to stay in quarantine for 7 days, while those with a green code can travel freely.

Chinese state media said the Alibaba system would be deployed at train stations, along major roads and other travel checkpoints. They added that the system is also being used in some neighborhoods. People are asked to show QR Codes when entering their apartment buildings. Customers are asked to do the same before entering the local supermarket. Alipay said it was working with the government to expand the system nationwide.

Tencent, which operates China’s popular messaging app WeChat, reported the launch of a similar QR Code-based tracking system. Tencent developed the system with help from China’s National Development and Reform Council, which is currently in use in the southern city of Shenzhen. Officials said they expected it to be deployed to other parts of Guangdong province soon.

Even before the latest systems were announced, many Chinese were already using mapping and travel apps in an effort to avoid areas with coronavirus infections. One of the apps, developed by WeChat, uses official reports to identify places in the cities of Shenzhen and Guangzhou where coronavirus cases have been confirmed.

One user of the apps told Reuters she finds the maps can provide “psychological comfort.” The woman, who did not want her full name reported, said: “You can’t guarantee there won’t be fresh cases, but you can avoid an area that’s already hit.”

The technology website Abacus reported that citizens can request location data from their mobile phone carrier to show they had not been in affected areas. The report said that if requested, China’s state-owned telecommunication companies will send users a message listing all the areas they had visited within the past 14 days.

【题目】 It happens from time to time that after a whole morning of studying, you are tired in the afternoon. It’s then that you might want to eat something sweet, perhaps a Coke or a chocolate bar, to lift your mood. After all it’s popularly believed that a “sugar rush” gives us energy.

But a study published in Neuroscience and Biobehavioral Reviews in April suggests that sugar can make us feel worse rather than boost our moods.

The German and UK researchers collected data from 31 studies involving nearly 1,300 adults. They studied the effect of sugar on various aspects of mood, including anger, alertness, depression and tiredness.

They found that people who have too much sugar become more tired and less alert within an hour and that these feelings become more intense over time.

According to the researchers, when people take in sugar their blood sugar levels rise rapidly, leading to a burst of energy and a short “feel good” period. However, as they begin to digest the sugar, their blood sugar levels decrease quickly leading to a bad feeling.

To remain on a “high” people are likely to eat more and more sugar until they become addicted to it. As with caffeine, this prevents the body from relaxing, leaving people feeling tired and less alert.

But the study findings needn’t make us think we must give up sweet food altogether. According to the World Health Organization, it is healthy to have the sugars found naturally in fruit, vegetables and milk so long as these make up less than 5 percent of daily total energy intake.

So the next time you feel tired and can’t concentrate, perhaps you should think twice before you bite into a chocolate bar. Maybe a spot of exercise at midday would be a better idea!

Tips for beating afternoon fatigue.

* Head outside and sit in the daylight for 10 minutes.
