The vaccinated and  the sickness of Omicron infection  

When vaccinated 3 doses,  the symptoms have been shown to be most  mild.The symptoms are similar to the common cold (Fever, Cough, Fatigue, Congestion etc.). When vaccinated 2 dose have more symptoms than 3 doses. Including more coughing, fever and fatigue than people who have 3 doses. One unvaccinated person died in his 50s with Omicron infection.The loss of smell and taste is uncommon. How long the incubation time for Omicron?According to data, the time for symptoms to develop may be shorter for omicron thant for other variants. The range is from 1 week to 3 days or lower. It is logical that a highly contagious virus would have a shorter incubation tiem as its goal is to infect as many people as it can. 

Lung and  Bronchial infection of Omicron

There is evidence that omicron often does not burrow deep inside the lungs as much as other variants. A study showed that omicron is less severe in the respiratory tract but it can replicate faster. Omicron can act closer to bronchitis then pneumonia. Patients tend to not have a shortness of breath but rather they often cough and produce sputum.

 What is Variants of concern (VOC)?

Utilizing comparative assessment bioinformatic methods, the sequencing information from  the new Sars COV2 staining showing the mutation meets the requirements to be a VOI. That means it has an increase in transmissibility, virulence Or, change in disease presentation, decrease in effectiveness of public health measures such as vaccines and diagnostics.  The WHO currently designated 5 types of Variant of concern including: Alpha, Beta, Gamma, Delta and Omicron.
