Mixed infection has occurred! Many places have issued reminders: Wear a mask!

Fever, cough, sore throat... With the arrival of the peak season for respiratory infections in autumn and winter, many people have reported that they or their children have symptoms of respiratory infections.
Recently, the number of outpatient and emergency visits in many hospitals has increased to varying degrees. Most of the patients are children, but there are also many adults who have been infected. In addition to the more well-known mycoplasma pneumonia infections, influenza, and new coronavirus infections, there are also bacterial infections and norovirus infections.

Experts remind us to be alert to the mixed infection of Mycoplasma pneumoniae with other pathogens that cause respiratory infections, such as adenovirus and Streptococcus pneumoniae. In addition, many places have issued reminders: Beware of all kinds of viruses, and wearing a mask is essential!

On October 23, "Healthy Guangdong" issued a statement pointing out that according to the monitoring of the Guangdong Provincial Center for Disease Control and Prevention: the level of influenza activity in Guangdong Province has increased recently. The main strain prevalent this time is the A (H3N2) subtype influenza virus. Citizens should take preventive measures as soon as possible. On October 27, the Jiangsu Provincial Health Commission announced the epidemic situation of legally reportable infectious diseases in Jiangsu Province in September 2023, and 8,194 influenza cases were found.

China CDC warns that there may be a risk of multiple respiratory infectious diseases spreading together

Previously, the Chinese Center for Disease Control and Prevention released a new version of the influenza vaccine vaccination technical guide, updating the types of influenza vaccines and vaccination recommendations for use in the domestic market in the 2023-2024 epidemic season. It pointed out that this winter and next spring, China may face the risk of interaction or co-epidemic of multiple respiratory infectious diseases such as influenza. This year, the respiratory syncytial virus in southern China experienced a peak in the epidemic. After a brief decline, it rose again as the temperature dropped. For children, syncytial virus and influenza can easily attack together. In addition, in previous years, respiratory syncytial virus mostly occurred in children under 2 years old, but this year, the infection of older children has increased.

Cao Ling, director of the Department of Respiratory Medicine at the Children's Hospital Affiliated to Capital Institute of Pediatrics, said that many children are infected with mycoplasma and then with viruses. Some children are infected with one virus and then another virus, or some are infected with three or four pathogens. These children usually have slightly weaker immunity, so it is not the case that they can only be infected with one pathogen at a time. When mixed infections occur, the condition is usually relatively serious.

How to prevent influenza?

The "Technical Guidelines for Influenza Vaccine Immunization in China (2023-2024)" points out that influenza vaccination is the safest and most effective way to prevent influenza , which can effectively reduce the risk of influenza infection, hospitalization, severe illness and death in autumn and winter. It is recommended that all people aged ≥6 months with no contraindications to vaccination should receive the influenza vaccine.

According to the guidelines, people aged 60 and above have the highest risk of death after contracting influenza and are an important target population for influenza vaccination. Patients with chronic diseases such as cardiovascular disease (except simple hypertension) and metabolic diseases (including diabetes), as well as medical staff, pregnant women, children aged 6-59 months, family members and caregivers of infants under 6 months old, etc. are also recommended as priority vaccination groups by the guidelines.

The Guangdong Provincial Center for Disease Control and Prevention also issued a reminder, advising the public to take preventive measures early and get the flu vaccine as soon as possible.

In addition, the Guangdong Provincial Center for Disease Control and Prevention emphasized that secondary bacterial pneumonia caused by Streptococcus pneumoniae is a common complication of influenza, especially in children and elderly patients with chronic diseases. It is recommended that the above-mentioned people receive influenza and pneumonia vaccines at the same time , which can save time and energy while obtaining double protection.

To prevent influenza, we need to do the following:

● Wash your hands frequently, use soap or hand sanitizer and run water, and do not wipe your hands with dirty towels. Wash your hands immediately after contact with respiratory secretions (such as after sneezing).

● Cover your mouth and nose with a handkerchief or tissue when sneezing or coughing to prevent droplets from infecting others. Flu patients should wear masks at home or when going out to avoid infecting others.

●During the peak influenza season, try to avoid crowded places with polluted air.

● Eat a balanced diet, exercise moderately, get enough rest, and avoid excessive fatigue.
