PEOPLE with the new stealthy Omicron subvariant show two new Covid symptoms that experts warn shouldn’t be ignored.
BA.2, which is super-fast spreading, has become dominant in England, overtaking the original BA.1 Omicron strain.
Health officials say there are two 症状 of BA.2 that are not always seen in patients infected with other variants.
Spokane Regional Health District (SRHD), in Washington, announced last week that people should look for dizziness and fatigue when trying to decipher if they have caught BA.2.
The symptoms were common in BA.2 cases, based on collected data, Medical Daily 已报告.

SRHD health officer Francisco Velazquez said it is crucial to monitor symptoms, especially the two newly reported ones.
But since they are not specific and could come from other conditions and diseases, he encouraged everyone to get vaccinated and boosted to lower the risk of infection.
People still associate Covid disease with a persistent cough, loss of smell and/or taste, and a high temperature.
While these still occur, the symptoms of the virus have largely changed due to new variants, and the effect of vaccination.
Fatigue and dizziness also occur with other strains, such as Delta and the original virus from Wuhan.
But reports suggest it is more common in BA.1 than ever before – and may be the first warning sign after infection.
BA.2 is spreading faster than any other strain before it, early data suggest.
至关重要, there is no signal that Omicron variants cause more severe disease. Multiple studies have shown BA.1 is more mild than Delta, and it’s thought this is the case for BA.2 as well.
But Professor Adrian Esterman, an epidemiologist and former World Health Organisation expert, has warned cases are going to “skyrocket”.
He wrote on 推特: “Omicron BA.2 is about 1.4 times more infectious than BA.1.
“The basic reproduction number (R0) for BA.1 is about 8.2, making R0 for BA.2 about 12.
“This makes it pretty close to measles, the most contagious disease we know about.”
Spending just 15 minutes with someone who has the measles is enough to spread it.
People who have previously had Covid are still at risk of getting the new variant, called a reinfection.

Brits who have tested positive for the bug have been logging their symptoms on the ZOE 冠状病毒 Study App.
