I spoke with American virology expert Dr. Hakim Djaballah Friday morning about the COVID-19 outbreak in Korea.



In New York, where he is based after stint as head of the Institut Pasteur Korea, he repeated: "This is bad." He was referring to a cluster of cases in Daegu and the first death in Korea from the Wuhan pneumonia epidemic.



Djaballah described the Daegu outbreak as a case of "community transmission," by which the disease can jump to pandemic proportions. It is because members of a community eat, drink and play together and live close, meaning a greater chance of contraction and contagion.



He called on Korean authorities promptly to account for those who the "super spreader" churchwoman in Daegu had contact with or the situation might get out of control. He said it is a race against time.



Djaballah, who proved prescient during Korea's 2015 MERS outbreak, said that with ground zero being a close-knit church, the government could not shut that particular church down or other places of worship without risking being accused of suppressing religious freedom, a basic democratic tenet.



If there is panic, people from Daegu might hit the road by train in an exodus and it would be a disaster. He said that in a worst-worst case scenario, "it could be a Wuhan in Korea."



The Chinese city, the epicenter of the disease, has seen tens of thousands of people sickened or dead. It has been under complete lockdown, a step only possible in an authoritarian country like China but next to impossible in a democracy like Korea.



Therefore, Djaballah raised the possibility of a potential "perfect storm" if tens of thousands of Chinese students return to Korea for a new semester in March.



"Campuses are a lot like churches in terms of the high risk of contagion," he said. "The next couple of days are important to better understand the situation. We had better brace for a worse situation than MERS."

The following is what Dr. Hakim Djaballah sent me after our conversation -- ED.



With the number of confirmed cases on the rise and the report of the first death on South Korean soil, is the government's preparedness and response adequate enough to contain the spread of the virus?



The past few days seem to suggest a lapse in the process due to the sudden and unexpected rise in cases on three subsequent days to over 100 confirmed cases. The landscape has changed dramatically with the a "super spreader" churchgoer in Deagu from COVID-19; South Korea has now a first SARSCoV2 cluster outside of China, joining Singapore and Germany. (The World Health Organization named the virus SARSCoV2 and the disease COVID-19).



The government response thus far has been very well balanced as not to upset their Chinese counterpart and at the same time control and reduce the number of visitors who can also be carriers of the SARSCoV2; and efforts to repatriate Korean nationals in the Wuhan region and quarantine them. I am impressed with the government's vigilance at the ports of entry without expensive monitoring throughout the rest of the country, especially rural places; but transparency is lacking in the way information is provided through the Korea Centers for Disease Control and Prevention (KCDC).



Many citizens would like to know the daily numbers of nationals and visitors entering the country and how their number correlates with the confirmed cases and their geographical location. Is this truly an imported virus or the virus has already settled in Korea; and what we are observing is the beginning of a bigger problem of a "local Korean cluster," where the spread is now via "community-based activities." If the upward trend continues for the next few weeks, then the government is heading toward a pandemic with a worse outcome than the MERS outbreak almost five years ago.

This time, they may not be as lucky as with the MERS outbreak. Closing churches and other places of worship is not the answer and would create unwanted stigmatism against their followers. The counter-argument would be to close all places and spaces where people can gather including airports, train stations, markets, cinemas, etc … The government must be cautious to avoid stigmatization and vulnerabilities.



The SARSCoV2 is similar in genomic content to the other members of the coronavirus family, but at the same time it is different in its mode of infection and, in particular, it seems to infect the pneumonia-causing bacteria colonizing the lungs such as Pneumococcal pneumonia or Streptococcus pneumonia, wake them up from dormancy and make them much more virulent than usual, thus speeding up lung inflammation and destruction, leading to severe pneumonia-associated symptoms. From the death cases in China to date, a common trend is that most of the deaths were associated with the elderly population prone to community-acquired infections and possibly with a history of pneumonia.



It is also important to note that there were not many reports of babies and young children being infected, showing symptoms, or dying from the COVID-19 disease. The reason perhaps why babies and young children are not generally infected with the pneumonia-causing bacteria at such a young age, and therefore seem to be spared, is because the virus is unable to enhance its virulence once it infects them. These children may remain carriers of the SARSCoV2 virus for a long time.
