Singer Eason Chan had just started a world tour. Unexpectedly, after completing three performances in Macau, he found that he had a bad cold and a runny nose. He had no choice but to postpone the performance, and finally recovered after a week of rest. He said that he was infected with “rhinovirus”, and experts pointed out that this virus has 4 characteristics, cannot be killed by alcohol, and is easy to be re-infected. If you want to prevent it, you should rely on 3 methods.
Eason Chan recently suffered from a severe cold due to rhinovirus. After returning to the concert, he described that his symptoms included nose inflammation, non-stop nasal discharge, and diarrhea, and he was later diagnosed with rhinovirus. It is the virus that most commonly causes the common cold and is named after the infection that causes inflammation of the nose. Both adults and children can be infected, but symptoms are more severe in children.
4 major characteristics of rhinovirus, which are the main culprits of common colds
In the past, rhinovirus often caused cluster infections. If it only caused a common cold, why should we be so nervous? Wu Changteng, the attending physician at Chang Gung Memorial Hospital in Linkou, analyzed that although the symptoms of rhinovirus are mild, they occur all year round and can easily cause repeated infections. Not only that, it is also “very good at bullying children” and is one of the important pathogens causing respiratory infections in children. He concluded that rhinovirus has four major characteristics, as follows:

It often causes repeated infections: more than 1/3 of common cold patients are infected by rhinovirus. Although a certain degree of immunity can be obtained after infection, and there is some cross-immunity between serotypes, there are more than 120 serotypes of rhinovirus, which means that immunity is not long-lasting and re-infection is easy. Severe symptoms in infants and young children: For young infants, premature infants, or children with chronic diseases, rhinovirus may cause serious complications such as asthma attacks, pneumonia, and central nervous system infection. It is also easy to be combined with mycoplasma, other viruses or bacteria, etc. So need to pay attention. It is a non-enveloped virus: therefore 75% dry alcohol hand sanitizer cannot effectively eliminate the virus, making it more difficult to prevent.
Alcohol cannot eliminate non-mantle viruses, here are 3 tips to prevent them
What are non-enveloped viruses? Most viruses have a “coat.” That is, when the virus replicates from a parasitic cell, it will also replicate the cell membrane of the cell, as if it were wearing a “coat” to deceive the immune system. However, alcohol can dissolve cell membranes, and of course it can also kill viruses with coated membranes.
However, viruses without a coat are called “unenveloped” viruses and are not easily killed by alcohol, such as norovirus and rotavirus that cause gastroenteritis; enteroviruses and polioviruses that cause enteroviruses, and viruses such as adenovirus Viruses, rhinovirus, chickenpox virus, etc. cannot be killed by alcohol. How to prevent it? Infection can only be avoided by washing hands frequently and disinfecting with diluted bleach. Wu Changteng said that we should keep in mind the three key points of prevention:

You need to wash your hands with soap and running water to effectively reduce the transmission rate. Wearing a mask: Since the COVID-19 epidemic, wearing a mask to prevent respiratory diseases has become a habit. A qualified mask can block virus-containing droplets. Use other tools for disinfection: Medical institutions, schools and other collective institutions can be disinfected regularly with alcohol, chlorine and other disinfectants. However, considering that disinfectants can cause certain harm to infants and young children, the use of disinfectants at home is not recommended.
However, now that the COVID-19 epidemic is slowing down, people’s vigilance in epidemic prevention has begun to decline. Not only are fewer people wearing masks, but also fewer people are washing their hands frequently, and at most they use alcohol to disinfect. But there are many pathogens circulating now, not only influenza and enterovirus, but also mycoplasma is quietly rising. Since some germs cannot be killed with alcohol, instead of just dry handwashing for prevention, it is better to re-cultivate the habit of wet handwashing and restart the epidemic prevention habits during the new crown epidemic. This can greatly reduce the chance of infection.
