The Director-General of the World Health Organization warned on Monday that there may never be "a silver bullet" for COVID-19.
"There is no silver bullet at the moment, and there might never be. For now, stopping outbreaks comes down to the basics of public health and disease control: testing, isolating and treating patients, and tracing and quarantining their contacts."
He stressed that the public should keep physical distance, wear masks, and wash their hands regularly.
The Director-General also added that an international team will be deployed to Wuhan, China, to look into how the COVID-19 pandemic began.
He said that an advance investigation team studying the origins of the virus outbreak has completed its mission in China, laying the groundwork for international experts to identify the source of the virus infection there.
"The WHO advanced team that travelled to China has now concluded their mission to lay the groundwork for further joint efforts to identify the virus origins. As a result of these efforts, WHO and Chinese experts have drafted the terms of reference for the studies and programme of work for an international team led by WHO."
The international team will be made up of scientists and researchers from all across the world, including China.
Meanwhile, a study by the U.S. Centers for Disease Control and Prevention revealed, in the 11 weeks before the WHO declared the global pandemic, 27 percent of the first confirmed cases outside of China were linked to travel to Italy, 22 percent to travel to China, and 11 percent to travel to Iran.
A CDC researcher said the findings suggest that travel to just a couple of nations may have "seeded additional outbreaks" worldwide.
