<Anchor> The



number of cold cases, which has greatly decreased due to the corona epidemic, is increasing again for the first time in three years.

Most of the quarantine measures seem to be the cause, but among the current cold viruses, there are some types that are as dangerous to infants and the elderly as the flu, so you need to be careful.



This is Cho Dong-chan, a medical reporter.

Kim has just passed the stone.



She had symptoms of a cold, but it was not corona or the flu, so I thought it would pass.



[Cold patient's guardian: (Child) I have had a cough and runny nose since last Thursday, but I have a high fever since Saturday night.

39.5 degrees, up to 40 degrees...

.]



Eventually, the cold turned into pneumonia, and the medical staff is even considering hospitalization.



[Min Taek-ki/Professor of Pediatrics, Soonchunhyang University Hospital: If you are less physically active than usual, or if you eat less, or if you urinate now, it is evidence that your condition is getting worse



. Over 1,000 people.



Among the many cold viruses, metapneumovirus and respiratory syncytial virus are leading the spread.



Both viruses have been shown to be just as deadly as the flu in a recent study for infants and the elderly.



Looking at the domestic trend graph of cold viruses over the past 7 years, several cold viruses that were quiet during the corona are on the rise as before Corona.



This year is the first time that Corona and a cold are spreading at the same time, and the fatality rate is higher if they are infected together.



As a result of a study at Seoul National University Hospital, it was found that 2.2% of hospitalized corona patients also caught a cold until last year, but it is highly likely to increase this year.



Conversely, the case of corona following a cold is not well known, but there are reports that some cold viruses alleviate the symptoms of Corona like vaccines.



Infants and the elderly should visit a hospital and receive active treatment if the high fever continues for more than four days and the cough worsens even if the corona and flu tests are negative.
