About sequelae

COVID-19 is a disease that can affect anyone, but symptoms vary from person to person when infected. Similarly, regardless of the presence or absence of symptoms at the time of infection, various symptoms may be seen as sequelae even after recovery from infection. This sequela is recognized in all ages, with a high percentage of people in their 20s and 30s developing this sequela.
The aftereffects may become more severe, and in order to prevent deterioration, it is important not only for the patient but also for the understanding of those around them, such as family members and workplaces.

[Examples of sequelae]
Severe malaise, brain fog (a type of cognitive dysfunction in a broad sense, such as fog in the brain) , coughing/sputum, taste/smell disturbance, dyspnea, fever, hair loss, etc.

See below for side effects.
