Corona virus: two subtypes of concern

The severity of these two subtypes is yet to be determined. The WHO said on Wednesday that they were behind a new wave of the Govt-19 epidemic in South Africa.


Study time: 2 minutes

LSouth African scientists who discovered Omigran late last year have flagged the other two Omigran subtypes, PA4 and PA5, due to an increase in cases in South Africa, ā€¯World Health Organization Director-General Tetros Adanom Caprais told a news conference.



“It’s too early to know whether these new subtypes will cause more severe disease than other Omigran subtypes,” but early data suggest that the vaccine may provide better protection against severe Govt forms and reduce the risk of death.

The Center for Epidemiological Response and Discovery (CERI) warned in late April that South Africa, which had been officially hit hard by the Covit-19 on the continent, had entered a new wave of epidemics.

The country, where less than 45% of adults have been fully vaccinated, experienced a 48-hour period without any deaths from Govt disease in early March, the first time since 2020. President Cyril Ramaphosa announced in early April that he would lift all restrictions. Legal restrictions on epidemics.

“Vaccination is the best way to protect the population, as well as proven community and public health measures,” Dr. Tetros said.

In Belgium, BA.2 is the most widely used variant

Between April 23 and 29, 4,785 confirmed govt cases were registered (-20%) and an average of 15.1 (-23%) deaths each day in Belgium, Cincinnati reports. Between April 26 and May 2, an average of 137.9 people were hospitalized each day, indicating a 22% drop.

The BA.2 sub variant of Omigran now represents more than 96% of Kovit cases listed in Belgium, more than 3% of the Omigran variant.

The symptoms associated with this subtype are similar to those of Omigran: runny nose, headache, fatigue, sneezing and sore throat. Other symptoms are sometimes reported: loss of appetite, muscle aches or mild fever.
