Since a Chinese-developed system to predict the spread of COVID-19 globally was launched online in May, 2020, it has predicted the daily numbers of infection cases of over 100 countries around the world, taking into account the impact of climate and environmental conditions, population density as well as government control measures.
The Global COVID-19 Prediction System was established by the collaborative innovation center of western ecological safety led by Lanzhou University in northwest China's Gansu Province.
Since the outbreak of the COVID-19 pandemic, researchers of the center have been working for three months to develop the system on the basis of the existing regional epidemic prediction model, said Huang Jianping, director of the center.
By creating the prediction model based on authoritative data, researchers will help explore the evolution mechanism of the epidemic and contribute to the establishment and improvement of the epidemiological model.
The infection and death figures they have used to establish the system are from the Johns Hopkins University of the United States, while the weather data, including the temperatures and humidity, are from the European Centre for Medium-Range Weather Forecasts and the National Aeronautics and Space Administration of the United States.
