Severe COVID-19 complications can progress rapidly
While most COVID-19 cases are currently mild or asymptomatic, the CDC warns that they can still progress to moderate or severe illness. People who test positive on rapid tests should pay close attention to the following warning symptoms:
Shortness of breath, rapid breathing
Persistent chest pain
Confusion, loss of consciousness
Blueish discoloration of the skin, lips, or nail beds
Inability to eat, drink, or take medication
No urination for 24 hours or a significant decrease in urine output
Systolic blood pressure <90mmHg or heart rate >100 beats/minute despite the absence of fever
If any of these symptoms appear, immediate medical attention is necessary, and the individual should be taken to a healthcare facility without delay.

Children with COVID-19 require heightened vigilance
The CDC advises parents to seek medical attention for their children if they exhibit any of the following signs:
A high fever >39°C with chills or sweating, lasting more than 48 hours
Prolonged fatigue and lethargy after the fever subsides
Rapid or labored breathing, wheezing, or chest pain
Persistent vomiting, headache, or abdominal pain
No food or water intake, or no urination for over 12 hours
Critical cases requiring immediate emergency care include:
Seizures, muscle twitching, unsteady gait
Prolonged confusion or coma
Difficulty breathing, chest recession with inhalation
Pale or blue lips or skin
Blood oxygen saturation below 94%
Cold hands and feet with mottled skin and cold sweats
Body temperature exceeding 41°C
New variants may be more transmissible among children
According to NOWnews, both COVID-19 and seasonal flu are respiratory illnesses that typically surge in the fall and winter months. However, this year, flu cases have decreased while COVID-19 infections have risen, possibly due to new viral variants and low vaccination rates.
Notably, “sore throat” is now the most common symptom in children with COVID-19, whereas it was rare in previous waves. Therefore, if parents observe sore throat along with body aches in their children, they should take the initiative to seek medical attention for their children as soon as possible.
