The results of a study conducted by scientists in Singapore showed the possibility of the rapid spread of the emerging corona virus through air conditioners, after they found traces of the virus inside the ventilation holes in the air conditioning units in a hospital in Singapore, which provides the speed for the transmission of infection.

The virus moved to Singapore at an early stage, as it is one of China's most important trading partners. Within a few weeks of the first official discovery of the virus, which was dubbed the Wuhan flu, about 12 cases had appeared in Singapore. But she quickly realized that the issue was not just a seasonal flu, and took swift action.

Armed with its experience with the SARS virus in 2002 and 2003, Singapore began tracking cases carefully to uncover links between them. Within a day or two of the discovery of each new injury, the authorities had come to define the complex chain of transfers that led, from person to person, as if it were a genius investigator armed with a database. Beginning in February, every person entering a government building or company building was required to provide detailed information about knowledge, family, and communication methods in order to expedite this process.

Not only was Singapore distinguished in its handling of the virus not only for its ability to detect cases and determine the cause of their occurrence, but it also quickly developed DNA test kits, distributing them to all entry points into the country. Within three hours, while individuals are quarantined at the point of entry, officials can confirm whether or not they have the virus before being allowed to enter.

On the other hand, the United States responded in a completely different way. From the start, most people assumed that this virus was a Chinese or perhaps Asian problem, because epidemics do not hit the United States. Because of that transcendent view, health authorities have been complacent in dealing with this problem. Dozens of infected people, and possibly more, were allowed to enter the United States, and the injured were allowed to go to work while they were ill, but were encouraged to do so, which accelerated the spread of the virus.
