According to the doctor, there are many ways to control myopia at present, including various concentrations of atropine, OK lens, some defocused frame glasses, and defocused contact lenses, all of which can help control myopia.
In daily life, it is recommended that children should be allowed to engage in outdoor activities as much as possible if conditions permit, so as to achieve a balance between work and rest. Zhu Mengjun, deputy chief physician of the Optometry Center of Shanghai Eye Disease Prevention Center, suggested:
■Two hours of outdoor activities can effectively prevent the occurrence of myopia, and help to slowly deepen myopia after it has already occurred.
■Everyone should combine work and rest. After studying for a period of time, a proper period of overlooking can help your eyes rest.

Norovirus "comes back" again
Four students in a high school in Zhejiang were infected with norovirus
Norovirus, also known as Norwalk virus, is one of the common non-bacterial pathogens that cause acute gastroenteritis. It occurs frequently in cold seasons, mainly through contact transmission and secretions of the digestive tract. Because norovirus is highly contagious, it often causes mass outbreaks in schools and childcare institutions.
The reporter learned from the Zhejiang Shaoxing City Center for Disease Control and Prevention that not long after the start of this semester, the center dealt with an outbreak of norovirus infection in a school. "A few days ago, we received 4 patients with norovirus acute gastroenteritis, all of whom were students from the same high school. "
Bao Yuquan, Director of the Public Health Department of the Affiliated Hospital of Shaoxing University of Arts and Sciences, who assisted in dealing with the norovirus infection outbreak, said, "Not only children are susceptible to infection, but people of all ages are susceptible to infection."
Doctor: usually after school starts
There may be a small peak of infection
In Hangzhou Xiaoshan Hospital, pediatrician Wang Baofeng told reporters, "Currently, norovirus group infection has not occurred in Xiaoshan, most of them are sporadic cases, and the number of patients with obvious gastrointestinal discomfort like norovirus is not many. "
Dr. Wang said, "But based on past experience , there may be a small peak of norovirus infection after school starts, as children's chances of contacting each other increase. "
It is reported that the incubation period of norovirus gastroenteritis infection is mostly 24 hours to 48 hours, the onset is acute, and the main symptoms are vomiting and diarrhea. The course of the disease is usually 1-3 days, and a few can reach 5 days, and the younger the age, the longer the course of the disease. Vomiting is common in children, and diarrhea is common in adults.
In addition, norovirus is a self-limiting disease. There is no specific antiviral drug yet. Do not blindly take antibiotics for infection. Generally, symptomatic treatment is used. Antiemetic, antidiarrheal, and prevention of dehydration are the key.
How to prevent norovirus?
Although norovirus is highly contagious, parents should not panic too much. The most effective measure to prevent norovirus infection is to maintain good hygiene habits. Wash your hands frequently, especially before eating and after using the toilet. Pay attention to food hygiene, such as taking out pre-stored food in the refrigerator and reheating it thoroughly before eating; washing raw vegetables and fruits must be washed; raw and cooked food processing utensils should be separated, etc.
In addition, Dr. Wang reminded the general public to focus on disinfecting the surface of environmental objects, daily necessities, food processing tools, drinking water, etc. contaminated by pollutants such as patient vomit and feces after infection. After infection, patients need to be isolated until symptoms 72 hours after disappearing completely.

The causative agent of "respiratory syncytial virus"
more and more attention
On February 10, the Chinese Center for Disease Control and Prevention issued a question and answer on the prevention and treatment of human respiratory syncytial virus (HRSV) infection, introducing authoritative knowledge about HRSV .
According to information released by the Health Communication Center of the Chinese Center for Disease Control and Prevention, HRSV is an RNA virus of the Pneumoviridae family and the genus Orthopneumovirus. After HRSV infection , the incubation period is usually 2-8 days. The clinical manifestations are mainly respiratory tract infection symptoms. Early HRSV infection is mostly confined to the upper respiratory tract, and the clinical manifestations are nasal congestion, runny nose, cough and hoarseness. Most symptoms of children with HRSV infection will disappear spontaneously within 1-2 weeks, and a small part may develop lower respiratory tract infection, mainly manifested as bronchiolitis or pneumonia, which is more common in infants under 2 years old. Clinical symptoms include cough, wheezing, Very few cases further aggravate shortness of breath and feeding difficulties, etc., and severe cases may develop respiratory failure.

"For children, we should pay attention to the impact caused by respiratory syncytial virus infection." Xu Wenbo, director of the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention, said that people of all ages can be infected with HRSV, but the high-risk groups of HRSV infection are mainly concentrated in children , the elderly and immunocompromised populations.
In terms of transmission routes, both symptomatic HRSV-infected persons and asymptomatic recessively infected persons can transmit the virus, usually through the following routes:
One is contact transmission, such as nasopharyngeal mucosa or eye mucosa coming into contact with virus-containing secretions or pollutants.
The second is close contact with patients coughing or sneezing.
Gao Zhancheng, director of the Department of Respiratory Medicine, Peking University People's Hospital, said that for the prevention of susceptible groups, we should wash our hands frequently, avoid touching the eyes, mouth and nose with unclean hands, develop good personal hygiene habits, wear masks in time, and reduce the density of people entering and leaving. place.
