• The clinical spectrum of COVID-19 infection appears broad, encompassing asymptomatic infection, mild upper respiratory illness, and severe viral pneumonia with respiratory failure and even death. (1)
• The incubation period for COVID-19 can extend to 14 days. The median time from exposure to the virus to the onset of symptoms was 4 to 5 days. (2)
• At the start of the disease, the most common symptoms are: fever, cough, fatigue and shortness of breath. Other less common symptoms are: headache, confusion, runny nose, sore throat, hemoptysis, vomiting and diarrhea.

Are children less infected, less exposed, better protected, less often symptomatic ?

Children are vectors of the Virus :

The pediatric population is an important vector of the disease, due to asymptomatic forms, recommend the Pediatric societies. (2,3). Transmission would be inter-human, the proof is that the children did not visit the Huanan Market where the first patients adults have contracted SARS-CoV-2. Children were susceptible to COVID-19 at all ages.(1)

Children are less seriously affected

The key points :

• Publication: Stanford University School of Medicine (California)
• The COVID-19 pandemic has led to a major shortage of N95 face masks equivalent to FFP2 masks, particularly among healthcare professionals.
• The Stanford team studied three promising disinfection methods that can be applied to the recycling and reuse of face masks :
  • Hot air (75°C, 30 min).
  • UV light (254 nm, 8 W, 30 min).
  • Water vapor (10 min).

They determined the following :

• “Test, test, test” is the key to controlling the spread of SARS-CoV-2 and its clinical manifestation, COVID-19, according to the World Health Organization.
• However, several months after the first coronavirus infection was reported in China, there is insufficient access to appropriate diagnostic tests worldwide and confusion among healthcare professionals and the public over the prioritization of testing and The interpretation of the results is so far present.
