Korean's leading infectious diseases in winter are influenza (influenza) causing respiratory diseases and Norovirus infection caused diarrhea.
◆ Influenza A (flu)
Influenza is an acute respiratory disease caused by Influenza virus and is popular in Korea from November to April. On November 16, the disease control headquarters issued a huge epidemic and called for compliance with personal hygiene regulations such as immunization, proper hand washing, and keeping cough striking to prevent influenza.
Influenza viruses are characterized by the presence of sudden high fever, muscular pain, headache, and respiratory symptoms, which are mainly transmitted by human contact in a tight environment.
◆ Flu vaccine prevention is required
The most important thing to prevent flu is vaccination. According to the Centers for Disease Control and Prevention, even if a full-fledged influenza epidemic has already begun, high-risk groups such as pregnant women and adults and adults need vaccination to prevent infection.
In particular, high-risk groups such as pregnant women, older people, children and people with chronic illness must be vaccinated because the flu pandemic increases the mortality rate. In the case of healthy adults, about 1 to 2 out of every 10 people are absent from the flu. Inoculation is recommended because the infected person often suffers from severe symptoms that may not take several days.
If the vaccine is inoculated, it can prevent the flu by 50-90%, and it can be easily even if it is ill. It is also important to keep personal hygiene, such as hand washing, in addition to vaccination to prevent influenza, and stop cough Etiquette to cover your mouth and nose to the top of your tissue or clothing sleeve when you cough.
"The flu vaccination is essential even when traveling abroad," said Dr. Kang Sung-yop, chairman of the Korea Medical Research Institute.
Central influenza usually occurs around the winter, but the tropical sub-tropical regions of Hong Kong, Taiwan, and Southeast Asia, which are popular with domestic travelers, are all the years of flood surge, regardless of the season. You should not worry that you will not get the flu in a warm country, considering your summer.
It is very dangerous because it can not tolerate the symptoms of influenza associated with high fever and severe myagenia in a hot overseas travel site, and it is not easy to use overseas overseas medical institutions. Therefore, it is important not to have a flu vaccine before traveling, but also to keep the rules for preventing infectious diseases while traveling abroad.
◆ Norovirus infection caused gastrointestinal disease
Norovirus is the subsequent agent of food poisoning and enteritis most commonly in winter in Korea. The prevalence of domestic rhinovirus infections is from November to April and is consistent with the influenza epidemic. Because Norovirus survives for several years at 20 degrees and may cause infections by less than 10 channels, it is common for large-scale patients to develop additional meals in large-scale restaurants or community centers such as schools.
Norweger infections are often transmitted by ingestion of food or water contaminated with viruses or contact with patients. In Korea, it is often said that contaminated drinking water or reproduction of seafood such as oysters, such as winter oysters, is the cause of the disease.
Injuries in infection go through a day to two days after infection, resulting in vomiting, diarrhea and stomachache. Prevention is best because vaccines or effective remedies have been developed.
Because Norovirus can withstand general disinfectants, it is safe to disinfect kitchen utensils, kitchen utensils, etc., which can contaminate the Norovirus with chlorine disinfectants (such as lactose).
Norwegian infections are often a problem when traveling abroad. Norovirus is the most important and common cause of food poisoning and enteritis in the world as well as in Korea, so it is not free of the risk of infection in Norway, regardless of where you travel around the world. Particular care is required because the cruise travel is a common impact on a large scale.
"In order to prevent Norovirus infections, we must wash our hands after using the toilet, after changing diapers, or before cooking," Kimi said. I have to eat enough to eat, "he said.
