According to official statistics, in the last days were regularly fixed cases where ill COVID-19 recognized and recovered again the people have been diagnosed as carriers of coronavirus. According to information on April 19, in South Korea altogether, there were already 179 cases and six of them yesterday.
Initially, doctors had hoped that those who have had it and won COVID-19, develop immunity to it, and therefore will not continue to get infected. This logic applies for vaccine development. In this context, it is understandable why re-infection cause this concern and much attention.
Judging by the published comments, South Korean doctors until they can’t exactly explain why, but all may not be as serious as some feared.
As stated yesterday, the head of the Centre for control and prevention of diseases under the MoH of the Republic of Korea Chung, Eun Kyung, “is currently still ongoing work to determine the causes and mechanism of re-infection”. Thus Jung refused to give any definite conclusions, but suggested that had the place not, strictly speaking, reinfection, and reactivation of the virus that was in the body. Previously, she and other experts suggested that perhaps the tests again revealed the “remains” has already defeated the virus. Note that the version of “bad tests” that supposedly gave the grounds to recognize healed those who were sick, not considered justified.
an Important fact is also that so far from 179 to “re-infected” no one was infected. At least it was not officially registered cases to re-diseased infected anyone again. This allows us to hope that really revealed any remnants of either the virus appears in an easy and relaxed form.
Officials provided additional information on the situation of re-infected. According to Chon, the average re-infection is recorded in 13-14 days after the patient COVID-19 was recognized as recovered.
Korean doctors say that COVID-19 is not yet fully understood, and therefore possible surprises and needed additional observations and analysis of the information.
Statistics reinfection in South Korea allows you to make some assumptions. In particular, it is possible that most re-infected or the most elderly or young patients. So, on April 19, total in the country, 179 cases, or 2.2 per cent of the total number recovered. But the proportion of re-infections in the age group 80 years and above – 10.5%, and from 0 to 9 years old – five percent. This suggests that these age most at risk of powto��tion identifying COVID-19 after recovery. In other groups the percentage ranges from 1.4 to 3.1 percent.
Other “clues” there are not so many. Of the 179 re-infected with most patients aged 20-29 years, 41 people, or nearly 23 percent. But there may play a role in this age group most represented among primary infections. And if you compare the frequency with which young people 20-29 years re-infected, it is only 1.8 percent, which is below the average of 2.2 percent.
Now some insights trying to do it on older people because at the age of 80 years or more abnormally high proportion of re-infections. For the same young patients it is difficult to say something definitely, since there are only five cases of re-infection for 100 recovered. It is too little for any conclusions.
Physicians and scientists of Korea noted that, in any case, with this situation it is necessary to understand how and why those who have recovered, are once again sick.
In General, General dynamics at COVID-19 continues to evolve in a favorable direction. According to midnight April 20 in the country for the day was was two deaths and 13 new cases with coronavirus, but it has recovered 72 human. The number of those who are currently listed as the patient COVID-19, in South Korea declined by 61 people. In General the numbers on 20 April of the following: all cases of diseases – 10 of 674, of whom recovered – 8114 (or 76 percent), the number of patients COVID-19 at the moment – 2324, died only 236 people, the mortality rate was 2.21 percent.
