In order to prevent influenza, pregnant women should not go to crowded places. Where there are many people, there is a high incidence of influenza. Because there are many people, everyone is very close. If one person has the flu, it is easy to infect another person. Wear a mask when going out to prevent people with flu from drooling.
Pay attention to personal hygiene. Pregnant women should keep their clothes and articles clean. Tableware such as bowls and chopsticks should be disinfected to avoid family transmission. Ensure ventilation in the house, and open the window every day for ventilation not less than 1 hour. Wash your hands properly with hand sanitizer. Keep warm and don't catch a cold.
Walk moderately, don't sit every day. Moderate exercise can strengthen the body's resistance, so it is not so easy to catch the flu. Never touch pathogens. For example, if your relative has the flu, you will kindly visit him. Don't go there. Don't touch the flu pathogen.
