Detecting a 2-sublineage hybrid variant of Omicron

The Israeli Ministry of Health said that it has just discovered a new variant combining two strains of BA.1. and BA.2 of the Omicron variant.

Two cases of infection were passengers at Ben Gurion airport. The unnamed variant causes symptoms including low-grade fever, muscle aches, and headache, and requires no special treatment.

“The world has not yet recorded this variant,” the Israeli Ministry of Health said. Cases of infection were diagnosed by PCR testing upon arrival at Ben Gurion airport.

Omicron currently has 3 branches including BA.1, BA.2, BA.3. Countries that have recorded a number of cases of former BA.1 infection continued to have BA.2. There are mixed results as to whether this reinfection causes more severe illness. However, the vaccine still seems to be effective.

The number of people being tested for SARS-CoV-2 in Israel has decreased. Even so, all international arrivals at the airport are sampled upon arrival.

The head of the Ministry of Health, Nachman Ash, assessed that the new variant may have originated in Israel. “It is possible that they were infected before boarding the flight in Israel,” said Mr. Ash.

“The phenomenon of variants coming together is well known. At this point, we are not concerned about the new variant leading to severe cases,” said Dr Salman Zarka.

Scientists also noted a combination variation between Delta and Omicron (Deltacron). However, the total number of cases is not much despite appearing for a long time.

Israel’s daily number of Covid-19 cases has fallen fairly steadily over the past month, from more than 30,000 in mid-March to just 6,300 now. This country has only 789 cases of treatment in hospitals with 335 critical cases and 151 people on ventilators. The number of deaths in the pandemic is more than 10,000 people.

Israel has always been a pioneer in vaccination in the world. Currently, 56.5% of the population of this country has received the 3rd dose. Those who are at high risk (elderly, have underlying diseases, are immunocompromised) are subject to the 4th dose.
