Answers
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
Answer:
Early in 2020, news of a virus infecting people was discovered to be a type of coronavirus. The epicenter of the viral outbreak was in the city of Wuhan in Hubei province in China. There were concerns the viral infection is spreading, after reports that all regions in China have cases. The more serious concern is its likelihood of spreading after the Chinese Lunar New Year celebrations, in which millions of traveling Chinese could have been exposed to the virus. Soon, cases outside of China were reported.
The world today is so highly interconnected, a contagion that can quickly spread diseases can lead to an epidemic as a worst case scenario. However, there are ways to prevent its spread in order to improve public safety. Since the most likely and common way for the virus to spread is through air travel, airports are becoming the checkpoints for screening passengers who have recently traveled to China. In the past, the screening process required a thorough checkup of every individual regardless of whether they are sick or not. It can be a long and tedious process, so other techniques have been explored to make the process more effective and efficient.
