UN / Geneva: The COVID-19 figures in the Southeast Asia region peaked in early May and have been largely plateauing over the last month, mainly due to cases in India that remained stable and consistent declines in Indonesia and Myanmar during the last month, the WHO has said.Read also – Videos Show Chinese officials putting iron bars on houses as delta variant cases rise | Watch

The weekly epidemiological update of COVID-19, released by the World Health Organization on August 10, said that the region of Southeast Asia reported over 799,000 new cases, a decrease of five percent over the previous week, however, several countries in the Region continue to report increasing trends, including Sri Lanka and Thailand (26 per cent and 20 per cent increases respectively).

“Cases in the region peaked in early May and have since been largely plateaued over the past month. This is largely due to the fact that cases in India remained stable and steady declines in Indonesia and Myanmar over the last month, ”the update states.

It added that following a sharp rise in mortality in the region, it is the first time in seven weeks that a decline in the number of new weekly deaths has been reported; a trend largely driven by declines in the Maldives and Myanmar this week.

Major increases in weekly deaths were reported in several countries, including Sri Lanka (47 percent increase), Nepal (35 percent) and Thailand (30 percent).

The highest number of new cases was reported from India (278,631 new cases; 20.2 new cases per 100,000; 2 percent decrease), Indonesia (225,635 new cases; 82.5 new cases per 100,000; 18 percent decrease) and Thailand ( 141,191 new cases; 202.3 new cases per 100,000; increase of 20 percent).

In the region, the highest number of new deaths was reported from Indonesia (11,373 new deaths; 4.2 new deaths per 100,000; 9 percent deaths), India (3,511 new deaths; 0.3 new deaths per 100,000; 8 percent deaths) and Myanmar (2045 new deaths; 3.8 new deaths per 100,000; 22 percent deaths).

Globally, cases of the Alpha variant have been reported in 185 countries, territories or territories, while 142 countries reported cases of the Delta variant, 136 countries reported cases of the Beta variant and 81 countries reported cases of the Gamma variant.

The update said the total number of COVID-19 cases globally exceeded 200 million globally on August 5, just six months after reaching 100 million cases.

This week alone, over 4.2 million new cases and over 65,000 new deaths were reported, a slight increase over the previous week. The largest proportional increases in new cases were reported by the Region of the Americas (14 percent) and the Western Pacific Region (19 percent), with 1.3 million and over 375,000 new cases, respectively.

Of the 228 Member States and territories, 38 (17 percent) reported more than a 50 percent increase in new cases compared to the previous week and 34 (15 percent) reported an increase of more than 50 percent in new deaths.

Nationwide, the largest number of new cases was reported from the United States with 734,354 new cases, an increase of 35 percent, India with 278,631 new cases; a decrease of two percent), Iran (248,102 new cases; 20 percent increase), Brazil (228,473 new cases; 8 percent decrease) and Indonesia (225,635 new cases; 18 percent decrease).

The update said that eight recent studies have assessed the impact of the Delta variant on the performance of COVID-19 vaccines.

It cited a peer-reviewed study from India which assessed the efficacy of the AstraZeneca-Vaxzevria vaccine in the prevention of SARS-CoV-2 infection and severe COVID-19 disease in a high environment. occurrence of the Delta variant.

The study from India showed that two doses of the AstraZeneca-Vaxzevria vaccine were 63.1 percent and 81.5 percent, respectively, effective in preventing infection and moderate-to-severe disease.

Single dose VE against infection (46.2 percent) was lower than two doses of VE, whereas single dose VE against moderately severe severe disease (79.2 percent) was similar to that for 2 doses.

It said that while this study was conducted at a time of high transmission of the Delta variant, it is noteworthy that virus sequencing and genealogy were only available from a small subset of positive cases (4.4%); of these samples, 90% were the Delta variant.

A report on the first local transmission of the Delta SARS-CoV-2 variant in China described viral infection and transmission dynamics for 167 cases traced back to the index.

Daily sequential PCR testing of quarantined individuals indicated that among those infected, the viral load at the first positive test of Delta infections was approximately 1000-fold higher than the original non-Variant Of Concern strain, suggesting the potential for faster viral virus replication and increased infectivity of the Delta variant during early stages of infection.
