Controlling Coronavirus is Becoming a Big Challenge for China

Last week’s reports on Coronavirus clears the picture that this global outbreak is still out of control. Controlling coronavirus is becoming more and more challenging with every passing day for China.

Coronavirus is transmitted from one person to another even when someone is not showing any signs or symptoms. People don’t remember from where they get the infection because the virus has a very long incubation period (nearly two weeks).

At first, it was thought that the virus is less zoonotic and is not proved fatal as compared to the Ebola and SARS virus. But currently, the danger has been predicted that it might cause many deaths as compared to previous viruses.

The virus was detected in late December in Central China. Till now 2829 cases were reported The number of people who got infected with the virus rose to 17,238  across the country and 361 died.  The infection has been spread in almost two dozen countries including the U.S. with 150 reported cases.

Dr. Anthony Fauci who is chief of the National Institute of Health’s Infectious disease said at the news conference that the risk of spreading coronavirus is less in American public and more efforts are being done to maintain the risk at a low level.

There are many factors involved in the outbreak of this virus and make it worse for people.

According to last week’s report of Chinese scientists in the New England Journal of Medicine that at first 425 cases of coronavirus are detected in China and on average, each case spread the infection to 2.2 others. The virus is the genetic cousin of the SARS virus and its flu is more severe as compared to ordinary flu.

Robert webster who has studied many outbreaks and an infectious disease expert at St. Jude Children Research Hospital said that the virus looks highly contagious and is transmitted from one person to another.

Webster further added that the full potential of the virus is unknown and still there is a need for more learning about the virus whether it will become more powerful or weaken when it spreads.

The main issue is the transmission of the virus from one person to another and its continuous spreading in the whole of China and other countries. Scientists are concerned about knowing the number of people who are infected and not showing any symptoms. This is known as asymptomatic transmission. It increases the burden of cases and makes it difficult to screen the infected patients because the detection of cases mainly depends on the symptoms.

Dr. Ashish Jha, a professor of the Harvard University global health said that if the virus is spread from one person to another without causing any symptoms then it will continue to spread for longer duration more than our expectations.

The mortality rate is 2 to 3% which is less than the SARS where the mortality rate was nearly 10% of the cases. The mortality rate of the flu is only 0.1% but it killed many people across the world during the whole year as it affects millions of people.

According to Lipsitch, the outbreak size can be based on the number of deaths it caused. The average incubation period is about five days, but it would last up to two weeks.

There is no test available for the detection of cases, so it is still not known how to determine the infected cases. The U.S. Center for Disease Control and Prevention has developed a test, but it is not accurate for the detection of cases.

Lipsitch said that the accuracy of this test is still unknown, and it creates a key gap. The need is to find any specific factor that will prove to be helpful in the detection of cases.
