At present, Guangdong has entered the season of heavy rainfall and strong convection, and the neighborhoods of Guicheng need to pay attention to the weather warning information, and they also need to be vigilant against "thunderstorm asthma" in this season!
After a thunderstorm, nearly 30 patients with "thunderstorm asthma" came to the hospital
On the evening of April 1, the central city of Chongqing ushered in a thunderstorm. From 0:00 a.m. to 1:00 a.m. on April 2, nearly 30 patients with "thunderstorm asthma" came to the emergency department of the Jiangnan Branch of the Second Affiliated Hospital of Chongqing Medical University.
Their symptoms are generally severe cough, shortness of breath, obvious wheezing, and a history of allergic rhinitis and recent upper respiratory tract infection.
"When I first arrived at the hospital, I was holding my breath so badly that I felt like I was dying, but I didn't expect it to be caused by a thunderstorm. A 34-year-old male patient in the hospital's emergency department sighed. Just two hours earlier, he was comfortably lying in bed looking at his phone, but soon felt breathless and rushed to the hospital. The man was diagnosed by doctors with "thunderstorm asthma".
What is thunderstorm asthma?
Thunderstorm asthma refers to an acute attack or exacerbation of bronchial asthma that occurs during or immediately after a thunderstorm, mostly during the pollen season, and can manifest as a large-scale outbreak of localized asthma, ranging from mild to severe and life-threatening. Most patients with allergies suddenly develop asthma symptoms such as cough, dyspnea, wheezing, and laryngeal edema induced by thunderstorms.
According to the doctor, "thunderstorm asthma" is an acute attack, generally showing a group of attacks, many patients have a simultaneous attack of the disease, can occur in people of any age.
Some studies have suggested that the cold air currents before a thunderstorm can carry pollen or mold particles into the clouds, and the moisture and lightning in the clouds can burst the pollen particles, releasing smaller particles that are easier to enter the respiratory tract.
People with pollen sensitivities need to take personal protective measures in the near future
At present, it is a period of high incidence of pollen allergies, and the "pollen index" of China Weather Network shows that many cities across the country have recently had extremely high pollen concentrations, including Beijing, Xi'an, Wuhan, etc.
Many sensitive people go out, and are prone to allergic symptoms such as sneezing, tears, and eczema after going out to enjoy flowers or walking
Last week, Ms. Lu from Hangzhou went out to enjoy the cherry blossoms. At that time, I felt that my nose was itchy and I was sneezing non-stop. The next day, she began to "snot and tears", and she was miserable. Ms. Lu immediately sought medical attention and was diagnosed with typical allergic rhinitis caused by pollen allergies.
"There are a total of 30 numbers in a specialist clinic on the weekend, and more than 20 people have allergic rhinitis. The number of such patients has increased by more than 30% compared with normal days, and almost all of them are allergic to pollen. The otolaryngologist of Hangzhou First People's Hospital said that most of the symptoms in this group of people are itchy nose and itchy throat.
Hangzhou's 67-year-old Wang Bo got up early for morning exercises, and after going out for a walk, his whole body was "fatter" than usual! The pimples on his lower back and the red rash gradually spread to a size larger than steamed buns, spreading to the back and thighs, and the itching was unbearable. What's even more terrifying is that his two eyes are swollen into "goldfish eyes", and his earlobes are also swollen, accompanied by symptoms such as shortness of breath, rapid heartbeat, and hand tremors.
After Wang Bo went to the doctor, he was diagnosed with systemic allergic symptoms caused by "poplar pollen allergy".
Therefore, it is recommended that people with pollen allergies wear masks and take personal protective measures during the time period when the pollen index is high.

How should citizens prevent "thunderstorm asthma" and pollen allergies? Guangdong CDC gives the following suggestions↓↓↓
1. Pay attention to weather forecasts, especially warnings of thunderstorms or meteorological changes, and it is recommended to close doors and windows and stay indoors as much as possible when thunderstorms occur.
2. Start at the source and cut off the allergens. During the pollen period, try to minimize the number of times you go out, except for the necessary ventilation of the windows, and usually close the doors and windows to prevent pollen from entering the room with the wind. If possible, air filtration equipment can be purchased.
3. When you go out, do a good job of protection, wear masks, glasses, and long-sleeved shirts. You can choose a place with less pollen, such as the seaside.
4. Take a shower and change your clothes when you get home. In case of severe allergic reactions, it is advisable to take allergy medications under the guidance of a doctor.
Guichengjun once again reminded that there have been many strong convective weather recently, and people with pollen sensitivity should pay attention to wearing masks, do a good job of personal protective measures, and forward and remind people around them~
