Whats Brewing In Vietnam? 1987 New COVID-19 Infections In Last 24 Hours And Growing Number Needing Supplemental Oxygen. New Sublineage Detected!
: Health authorities reported 1987 new COVID-19 infections in Vietnam over the last 24 hours. The figure represents a huge rise over the previous day of only about 1050 reported infections.
As very minimal COVID-19 testing is being done, local physicians warn that the actual numbers could be much higher.
Another interesting development is that the number of individuals needing supplemental oxygen is also growing with 76 hospitalized cases now on supplemental oxygen.
No COVID-19 Deaths were reported in the last 24 hours but then it should be noted that the manner of classifying COVID-19 deaths in Vietnam is a bit misleading and many unexplained deaths are often not even tested for COVID-19.
According to the CoV-2 Spectrum platform, there are more than 21 different types of XBB sub-lineages circulating in Vietnam including the various spawns of the XBB.1.5, XBB.1.9 and XBB.1.16 variants.
However, researchers and variant trackers have recently identified a new XBB.1.9.1 sub-lineage spotting the spike mutation F456L in Vietnam. The new sub-lineage besides the mutations found on the XBB.1.9.1 variant, also carries additional mutations like C28846T and G2174A(orf1a:E637K).
There is no evidence that this new sub-lineage increases risk of disease severity or mortality nor are there any data yet about its pathogenesis, immune evasiveness etc. However, its emergence coincided with the increasing number of new COVID-19 infections needing supplemental oxygen.
Another worrying trend to note is that there is very little genomic sequencing being conducted in Vietnam and as such it would be difficult to ascertain as to what new sub-lineages could be driving disease severity or hopsitalizations.
In a related COVID-19 News
coverage by the media outlet: VietnamNet, it was reported that the Deputy Director of the Department of Medical Examination and Treatment under the Vietnamese Ministry of Health, Dr Nguyen Trong Khoa had warned that the death rate from COVID-19 higher than that from other infectious diseases in Vietnam.
He said that the death rate from COVID-19 at present is 0.37 percent which is still higher than the death rate from ot
her infectious diseases which stands at about 0.09 percent. He stressed that it was essential to continue to be vigilant in addition to detecting cases early and improving the capacity of the resuscitation system and limiting cross-infection in hospitals in order to reduce COVID-19 mortality rates.
The Vietnamese Ministry of Health on the average, the number of deaths recorded in the past 7 days was one death a day. However, it was concerning that there are now about 100 severe COVID-19 patients are requiring supplemental oxygen and the situation is being monitored closely in the country.
