Omicron Subvariant BA.2 Is Rising. What Do We Know About It?

Published

on

Two years into the COVID-19 pandemic, and just when new cases and hospitalizations in the U.S. are on the decline, an Omicron subvariant called BA.2 is gaining significant traction in some parts of the world.

Dr. Dorit Nitzan, a World Health Organization regional director, told the Jerusalem Post on Monday that Omicron BA.2 is likely to become dominant worldwide due to its high transmissibility. “The expected trajectory is that it will become the new dominant variant, as once it crosses past a certain threshold it becomes dominant — like we’re seeing in Denmark and the U.K.,” Nitzan said.

While the original Omicron variant, first detected in South Africa in late November, is still responsible for the majority of new cases in most countries, BA.2 has rapidly spread in places such as South Africa, India, England and Denmark, where it is now dominant.

In the U.S., Omicron BA.2 is circulating at a low level, accounting for less than 4 percent of new coronavirus cases, according to the Centers for Disease Control and Prevention. But some experts believe it is just a matter of time until the subvariant takes over and becomes dominant.

“Anytime a variant is more transmissible, even if it’s a little more transmissible, it seems to have taken on that dominance,” Dr. Monica Gandhi, an infectious disease specialist and professor of medicine at the University of California, San Francisco, told Yahoo News. “So Delta was much more transmissible than Alpha. It took over. Then Omicron was four times more transmissible than Delta. It took over. If the BA.2 is more transmissible than BA.1, it’ll take over,” she said.

According to public health experts in both Denmark and the U.K., the variant appears to be between 30 and 34 percent more infectious than the currently dominant BA.1 form. A recent Danish study also found that BA.2 was relatively better than BA.1 at infecting vaccinated people, which indicates the subvariant has greater “immune-evasive properties.”

But, underscoring the value of vaccines, the researchers found that vaccinated people were still less likely to get infected and transmit either the BA.1 or BA.2 subvariant compared with unvaccinated people.

The good news is that there are no indications so far that BA.2 causes more severe disease. In addition, Gandhi says it’s a good sign that the subvariant hasn’t accelerated the pandemic in Denmark and the U.K. “Cases still were able to go down there, despite BA.2 coming into their regions,” Gandhi told Yahoo News.

Data on Omicron BA.2 is still limited, and it is uncertain what impact the strain will have on the future of the pandemic. Gandhi says booster shots are the best way to protect yourself and your community from both Omicron subvariants.

Her point is supported by recent U.K. data that showed booster protection against symptomatic COVID-19 infection was 70 percent for BA.2 and 63 percent for BA.1.

“What we need to get through this time is immunity. … If we got a booster, it would help raise our antibodies and stave off even mild infections. So getting a booster is an important strategy,” Gandhi said.

Three – Day Strike Looms As Lagos Doctors Issue Warning

Published

By

Medical doctors employed by the Lagos State Government have announced a three-day warning strike scheduled to commence at 8:00 a.m. on Monday, July 28, 2025, in protest against what they described as the “unlawful and disrespectful” deduction of their salaries by the state.

Operating under the Medical Guild, the doctors said the strike action follows failed efforts to resolve the dispute through dialogue. The industrial action is expected to conclude by 8:00 a.m. on Thursday, July 31, 2025.

At a press briefing held at the Guild’s secretariat in Lagos, the chairman, Dr Japhet Olugbogi, explained that the impasse began in April 2025 when the state government unilaterally deducted salaries from medical and dental officers without prior consultation.

He noted that although many of their members initially demanded an immediate strike, the Guild’s leadership opted to pursue a more diplomatic route through negotiation and advocacy.

“Following persistent engagement, the deductions were reversed, and a six-member conciliation committee, comprising representatives from both the Guild and the government, was set up,” Olugbogi said. “It was agreed that all parties would maintain the status quo until a resolution was reached.”

However, the Guild accused the Lagos State Treasury Office of violating the agreement by implementing another round of deductions in July, which triggered the decision to embark on the warning strike.

The Guild is demanding:

An immediate reversal of the July salary deductions

Full payment of 12-month revised CONMESS arrears owed to honorary consultants at Lagos State University Teaching Hospital, LASUTH

The union also issued a 21-day ultimatum, warning that failure to meet its demands could lead to an indefinite strike.

Dr Olugbogi expressed deep concern over the growing instability within the state’s health sector, exacerbated by economic hardship and the ongoing exodus of medical professionals from Nigeria.

“It is disheartening that the most senior medical doctor in the Lagos State system earns less than $1,100. Instead of supporting our members, the government is cutting from their already inadequate income. This cannot be allowed to continue,” he said.

He appealed to Governor Babajide Sanwo-Olu to intervene urgently to prevent a collapse of healthcare delivery across the state.

According to the Guild, more than 385 doctors participated in the emergency congress where the strike was ratified unanimously.

The Guild’s Secretary, Dr Adekunle Akinade, confirmed that the union is prepared to escalate its measures if the government does not respond swiftly to their demands.

Lagos State Government has activated its Emergency Response Committee following a diphtheria outbreak in the boarding house of King’s College, Lagos, Victoria Island Annex.

The Commissioner for Health, Prof. Akin Abayomi, confirmed the outbreak and assured the public that the situation was under control.

He urged residents to avoid panic as the government intensified measures to contain the infection.

The outbreak was first detected on February 22, when a 12-year-old student presented symptoms and was admitted to the Lagos University Teaching Hospital (LUTH).

Despite receiving treatment, he succumbed to myocarditis, a severe complication of the infection, on March 6.

Health officials identified 34 close contacts, with 14 developing symptoms. Of these, 12 were admitted for treatment and are recovering.

The government has begun strengthening infection prevention measures at the school and plans a targeted vaccination campaign for students and healthcare workers.

Abayomi emphasized the importance of hygiene, early detection, and vaccination to prevent further infections.

The state has 500,000 doses of diphtheria vaccine ready for deployment in high-risk areas.

The Emergency Operations Centre will meet daily to assess and respond to the situation.

Health authorities, including WHO, NCDC, and NPHCDA, are collaborating with the Lagos State Government to curb the outbreak and protect residents.

Power Outage: UCH Resident Doctors Begin Indefinite Strike

Members of the Association of Resident Doctors, ARD, at the University College Hospital, UCH, in Ibadan have embarked on an indefinite strike, an official said on Monday.

The Association’s General Secretary, Dr. Uthman Adedeji, told the News Agency of Nigeria, NAN, in Ibadan that the strike was due to power outages in some of the hospital’s residential areas.

The Ibadan Electricity Distribution Company, IBEDC, reconnected UCH on Wednesday after more than 100 days of power outage.

The association had earlier issued a communique stating that members would embark on an indefinite strike if electricity was not restored by 4 p.m. on Monday.

Adedeji said that while electricity had been restored, only some parts of the residential quarters were reconnected.

“Arising from the just-concluded Emergency General Meeting, EGM, of ARD UCH, which was convened to appraise the current situation, it was observed that part of the residential quarters was reconnected. Some other parts were, however, left in darkness.

“In light of the prevailing circumstance, we are left with no other option than to embark on the earlier planned total and indefinite strike until all residential quarters are sorted (taken care of).

“We acknowledge the efforts of the UCH Management towards meeting our demand, but a lot needs to be done in order to guarantee uninterrupted service delivery.”

Adedeji assured that the association would regularly review the current imbroglio infringing on the welfare of its members.
