支原体肺炎以持续性、痉挛性咳嗽为特征，有时和百日咳引起的咳嗽类似，可伴有发热、呼吸困难和咳痰。

Typical symptoms of mycoplasma pneumoniae infection include persistent and spasmodic coughing that is sometimes similar to the coughing caused by pertussis (whooping cough). Fever, difficulty breathing, and coughing up of phlegm may also occur.

持续高热是一个需要引起大家警惕的特征，可以说是具有重症倾向的危险因素之一。

Persistent high fever, which is a risk factor for severe cases, is also something to be mindful of.

其他重症的早期预警指标还包括：治疗后低氧血症和呼吸困难难以缓解或进展、存在哮喘和原发性免疫缺陷病等基础疾病。

Other early warning signs for severe illnesses include persistent or worsening hypoxemia (low blood oxygen levels) or difficulty breathing, as well as underlying diseases such as asthma and immunodeficiency diseases.

肺炎支原体感染广泛存在于世界各地，平时散发性发病，每隔3-7年出现一次地区流行，每次流行持续1-2年。

Mycoplasma pneumoniae circulate sporadically throughout the year, with regional epidemics recurring every three to seven years and each epidemic lasting for one to two years.

在社区、家庭内或聚集人群中可以有流行感染，暴发则往往在学校、托幼机构、夏令营等封闭群体中。

It can circulate in communities, families or gatherings, and infection clusters often occur at schools, nursery care centers or summer camps.

Domestic spread of the disease has been rising since 2015 and peaked in 2019. Due to virus control measures rolled out during the COVID-19 pandemic, infection numbers declined significantly in subsequent years until the latest outbreak emerged.

今年是肺炎支原体在新冠疫情放开后的第一次流行。

The current wave of mycoplasma pneumoniae is the first to occur since COVID-19 containment measures were lifted.

从目前的医院的收治情况来看，混合感染的多，耐药的多，大叶性肺炎变多，整体来势凶猛，同既往流行有明显不同。预计未来一个月是高峰。

Compared to previous years, we have found more patients with mixed infections, drug resistance and lobar pneumonia. This wave is intense, and we expect to experience the peak of the outbreak throughout the next month.

新冠疫情期间，大家一直采取戴口罩、勤洗手、保持社交距离等方式防疫，没有机会接触肺炎支原体，导致易感人群增加和群体免疫变差。

Implementation of COVID-19 control measures such as wearing masks, frequent hand-washing and maintaining social distance has led to limited exposure to the bacteria across the population. As a result, the number of susceptible individuals has increased and herd immunity has declined.

疫情放开后，人们再次接触肺炎支原体时就会出现免疫过激反应，出现流行。
