Hanoi dense fog increases risk of infectious diseases

On the morning of February 2, Hanoi residents were surprised by the fog that covered the area, obstructing visibility and making the floors damp.

According to information from the National Center for Hydro-Meteorological Forecasting, fog occurs due to the difference in humidity and temperature of the air. In winter, low temperature and high humidity combined with very weak wind speed in winter, even no wind. These are 3 important factors for the formation of fog.

Associate Professor, Dr. Tran Dac Phu, former Director of the Department of Preventive Medicine ( Ministry of Health ), said that fog can potentially affect health, because increasing humidity in the air will create conditions for bacteria and viruses to grow.

The current air humidity will affect people with bone and joint problems, cardiovascular problems, and underlying medical conditions. In addition, the fog also leaves smoke, dust, and toxic substances in the air, which will be very harmful to health.

Especially during the time before Tet, the demand for travel increases, making it easy for infectious diseases to spread through the respiratory tract.

To maintain health, Associate Professor Tran Dac Phu recommends that people should limit going out in the early morning, especially children, the elderly, people with underlying medical conditions, and pregnant women. If you need to leave the house, you should wait for the fog to clear so that the toxic substances in the air can rise higher.

When traveling on the street, people should use medical masks to prevent toxic gases in the fog; should not exercise outdoors in the early morning when there is fog. When indoors, it is necessary to dehumidify and turn on the air conditioner to limit the growth of bacteria and viruses that cause illness in the family.

In addition, people need to go to a medical facility promptly when there are signs of respiratory illness to avoid worsening and danger. People with bone and joint problems and chronic diseases need to pay attention to their health when there are signs that they need to go to a medical facility for immediate examination.

People should also note not to dry clothes outside overnight, but should dry and iron clothes to kill mold on clothes to avoid skin diseases...
