The first known case of omicron in the US was found in a person who had traveled internationally, according to the Centers for Disease Control and Prevention.
omicron arrived in the U.S. earlier than thought. The first confirmed case was reported by California. An international traveler returned to San Francisco from South Africa and developed symptoms three days later.
The CDC said that 22 states have confirmed at least one omicron case. According to the CDC, 32% of omicron patients reported international travel before symptom onset or testing positive.
Exposures associated with international and domestic travel have been identified.
There are large public events.
There have been no deaths reported among the patients who have been followed by health officials, according to the CDC.
The majority of the patients were between the ages of 18 and 39 years old, and most were fully vaccined at least 14 days before symptom onset or testing positive. According to the CDC, fourteen people had received booster doses and six had recovered from previous Covid infections. The five who received their booster dose less than 14 days before symptom onset were the only ones.
The most common symptoms were cough, fatigue and congestion.
Many of the first reported cases of Omicron variant infection appear to be mild, although as with all variants, a lag exists between infection and more severe outcomes, and symptoms would be expected to be milder in vaccine recipients and those with previous SARS-CoV-2 infections than in unvacc
More data is needed for conclusive answers, but the World Health Organization says omicron appears to be more contagious than the Delta variant. White House chief medical advisor Dr. Anthony Fauci said early reports of mild symptoms are encouraging, but more data is needed to determine the severity of the disease.
The U.K. Health Security Agency warned that omicron is showing a growth advantage over delta. Omicron infections in the U.K. could top 1 million by the end of the year, according to the Health Secretary.
