Science: Keeping social distance helps China control the outbreak more effectively

BEIJING, June 30 (Xinhua
) -- China has adopted strict restrictions to urge people to keep their social distance in the early stages of the outbreak of new crown pneumonia, an international research team wrote in the latest issue of Science. But the U.S. states are separate, and although measures have been taken since then to reduce interpersonal contact, the effect has not been significant.
china's measures have been successful, with the number of new cases per day stabilizing in less than a month and slowing since then, he said. "Reducing human-to-human contact has really reduced the severity of neocycline pneumonia in China, and our study shows that keeping social distances played a big role," said Alessandro D'Sbiani, one of the authors of the paper and director of the Institute of Cyberscience at Northeastern University. But
is a different story, according to the researchers. U.S. states have been separate, and although measures have been taken to reduce human-to-human contact and slow the spread of the new coronavirus, they have not stopped. The number of new cases has decreased in some U.S. states, but the number of new cases is increasing in others.
, the epidemic is slowing, but at a slow pace, he said. We are now in a situation similar to the peak of the outbreak in Europe, where neo-crown pneumonia only slowed in February. The measures taken by China are more stringent than among the United States, which greatly reduces the chances of human-to-human transmission of the new coronavirus. During the "city closure" period, Chinese between the two countries decreased seven to nine times, and almost all of the connections occurred within the family.
is really a very effective way to stop the epidemic of neo-crown pneumonia, " he said. Although it is still possible for infected people to transmit the new coronavirus to the rest of the family, it is not possible to spread it further. If no new people are infected, the epidemic will gradually disappear.
's latest study is based on a previous study by Chinese scientists, who stumbled across a study of human-to-human contact patterns in Shanghai before the outbreak of coronary pneumonia, and then repeated it during the "sealing of the city".
first time that scientists have been able to compare normal life patterns with between 2007 and 'sealed cities', " said Sbianiani, a member of the National Security Council. In
, the researchers also found that children appear to be less susceptible to neo-corona pneumonia -- although the exact cause is still unknown. 'Our study found that children under the age of 15 are only one-third more likely to develop new coronary pneumonia, and those over 64 are more likely to be infected with the disease,' said Marco Ajali, a computational epidemiologist at the Bruno Kessler Foundation in Italy and co-leader of the study.
