A new Covid-19 AI tool from Tencent could tell doctors if patients are likely to become severely ill
- The tool uses a deep learning model to assess a patient's risk of critical illness from Covid-19
- Chinese scientists, including renowned doctor Zhong Nanshan, have been working with Tencent on the new AI tool

Assessing a lung scan for a Covid-19 patient can take anywhere from five to 15 minutes. Determining whether a patient is at risk of becoming critically ill from the coronavirus could take even longer. That’s why some scientists are now trying to speed the process up with the help of artificial intelligence.
The tool is based on a deep learning model using data from nearly 1,600 patients from different medical institutions. To predict a patient’s risk level, the scientists narrowed down a list of features to what they found to be the 10 most relevant ones. These include X-ray abnormalities, age, cancer history and more. These were then used to establish the AI model for risk prediction.

The tool is another example of tech giants using AI for medical applications. In the US, IBM has Watson for Health and Google has DeepMind Health. In addition to Tencent, other Chinese tech giants, including South China Morning Post owner Alibaba, have been using AI for everything from better diagnostics to drug research. Deep learning models have already been used to diagnose skin cancer and other types of carcinoma.
