Lubango central hospital in Angola is under pressure due to the growing number of patients, reporting the possible collapse of the system. In the Angolan province of Huíla, local health authorities are concerned with the increase in deaths and cases of Covid-19, especially since the beginning of May. The province recorded 14 deaths in the last seven days, an average of two a day, in addition to an increase in hospitalizations for serious and critical cases at the central hospital in Lubango.
In view of the worsening situation and the fear of collapse in the health system, local health authorities are reiterating calls to the population to redouble preventive measures and announced the opening of four new Covid-19 patient care centers in the municipalities of Chibia , Kuvango, Jamba and Cacula and thus try to stop the wear and tear in the largest hospital in the region.
Uganda was the first country on the continent to confirm the presence of the B.1.617 variant first identified in India late last year.
This variant has now been reported in Kenya, Morocco, Algeria, South Africa, Botswana, Angola, DR Congo, Nigeria, Uganda, Zambia and Zimbabwe.

Forbes are carrying an interesting about the recently discovered coronavirus variant found in Tanzania, Africa in travellers arriving from Angola. The variant is from “From An Entirely New Branch Of SARS-CoV-2”, and carries Spike mutations E484K, P681H, T478R, Q957H, H655Y, D215G, D80Y. L210N, W258L, R246I. “An additional 18 amino acid changes occur in proteins outside the spike protein. These include 14 in the orf1ab proteins that specify the replication complex. “
“This is a remarkable illustration of convergent evolution,” say’s Forbes
“We detected a new VOI in three incoming travelers from Tanzania who were tested together at the airport in mid-February. The three genomes from these passengers were almost identical and presented highly divergent sequences within the A lineage. The GISAID database contains nine other sequences reported to be sampled from cases involving travel from Tanzania, two of which are basal to the three sampled in Angola”
This new VOI, temporarily designated A.VOI.V2, has 31 amino acid substitutions (11 in spike) and three deletions (all in spike) (Figure 1C & 1D). The spike mutations include three substitutions in the receptor-binding domain (R346K, T478R and E484K); five substitutions and three deletions in the N-terminal domain, some of which are within the antigenic supersite (Y144?, R246M, SYL247-249? and W258L)4; and two substitutions adjacent to the S1/S2 cleavage site (H655Y and P681H). Several of these mutations are present in other VOCs/VOIs and are evolving under positive selection.
The most mutated variant of the coronavirus yet was found in travellers from Tanzania. A report submitted to the World Health Organization and regional bodies shows the strain has 10 more mutations than found on any other version, according to Tulio de Oliveira, director of Krisp, a scientific institute that carries out genetic testing for 10 African nations.
Krisp, which discovered a new strain in South Africa last year that propelled a resurgence of infections in the country, found the new variant in travellers arriving in Angola from Tanzania.
