Yeah, that place out 'there'. Anything not really Cambodia related should go here.

Overweight and Obese Americans Make up 78% of COVID-19 Hospitalization, CDC Warns

A study by the Centers for Disease Control and Prevention (CDC) warns that the majority of COVID-19 hospitalization, ventilators used, and deaths are dominated by overweight and obese Americans.

Last week, the World Obesity Federation using data from the Johns Hopkins University released a study entitled, "COVID-19 and Obesity. The 20201 Atlas" showing the dramatic correlation between obesity rates and international death rates.

The study found that countries like the US and the UK, with nearly half of their population classified as overweight or obese, have higher death rates per capita compared to countries with lower adult obesity rates such as Vietnam with only 18.3%.
Obesity and COVID-19

Roughly 8 in 10 patients hospitalized due to the coronavirus were either overweight or obese according to a study by the CDC entitled, "Body Mass Index and Risk for COVID-19-Related Hospitalization, Intensive Care Unit Admission, Invasive Mechanical Ventilation, and Death--United States, March-December 2020."

The study highlights that out of 148,494 adults that received COVID-19 diagnosis in emergency departments or inpatient visits at 298 US hospitals, from March to December 2020, 71,491 were hospitalized.

Among those hospitalized 27.8% were overweight while 50.2% were obese.

The CDC defines overweight as having a body mass index of 25 or higher, while obesity has a BMI of 30 or more.

The study found that hospitalization risks, ICU admissions, and deaths were lower with individuals with under 25 BMIs. The risks of severe illnesses dramatically increased as a patient's BMIs rose especially for people 65 and older.

According to the agency, obesity contributes to serious illnesses due to excess weight impairing proper lung function and may disrupt the body's immune response.

Comparison of some vaccines - they are better in real world scenarios than in trials.
This is a good summary. It seems real world data shows high levels of efficacy with all the leading vaccines, often much better than in their trials. It points out that the trials were different between vaccines and thus it’s hard to make direct comparisons, whereas real world data is directly comparable.


Vaccines comparison
A few months ago the biggest question about covid-19 vaccines was whether any of them would work. Today the problem in some countries is having too many to choose from. In Europe some people are spurning AstraZeneca’s jab, preferring to wait for Pfizer’s or Moderna’s instead.
Such preferences stem from the results of clinical trials. Moderna and Pfizer, which make the same type of vaccine, announced an efficacy of 94-95%, whereas Johnson & Johnson and AstraZeneca reported 63-66%. Emmanuel Macron, France’s president, has maligned AstraZeneca’s jab as “quasi-ineffective” in older patients.
However, the gap in reported efficacy may say more about the trials than about the vaccines themselves. Some studies counted people with mild symptoms as positive cases; others did not. Those with lower reported efficacy used participants in countries where partly immune-resistant variants of sars-cov-2 are common. One tested only a single-dose regimen.
Fortunately, apples-to-apples comparisons are now possible, based on millions of people who got different vaccines in the same country at the same time. And recent data from Britain, which has given either Pfizer’s or AstraZeneca’s jabs to 20m people, paint a different picture from the trial results. Three studies show that single doses of the two jabs are similarly effective.

The latest paper, a preprint for the Lancet published on March 3rd, found that one dose of either jab is 80% protective against hospitalisation in people aged at least 80, starting 14 days after vaccination. Another study, in Scotland, included younger age groups and also found the two jabs had similar potency against hospitalisation.
For a virus seeking new hosts, this is bad news—which will only get worse. Few people in Britain have received second doses. However, Israel has almost finished a two-dose mass- vaccination programme using the Pfizer vaccine. According to the latest data from Israel, two doses are about 90% protective against any form of covid-19, including asymptomatic infection.
Pfizer’s jab is pricey and must be stored in freezers. In contrast, AstraZeneca’s is cheap and needs only normal refrigeration. If the AstraZeneca vaccine also matches Pfizer’s efficacy, which now appears likely, it could play a leading role in ending the pandemic—so long as people do not reject it based on ill-founded swipes from the likes of Mr Macron.■

In countries that have the scientific ability to evaluate the virus and detect and sequence a new variant, these scares will keep coming up. In a country like Cambodia you have to question if they know what strain they are dealing with.

On February 23rd it was reported that 3 cases of the UK variant were discovered here. However, there were only two imported cases that day, both Cambodian UN peacekeepers from Africa and the report did not say they were part of the 3. At least one must be of a community transmission nature and that's the tip of the iceberg.

Since then there has been no mention of it again. This strain is more contagious and has become the dominant strain the UK and also set to become so in Germany and the US. It is also reported in recent studies to be more deadly than the previous one.

Yet all is quiet here about what is circulating.

Does it really matter what variants are circulating? The measures and precautions taken against all variants are the same.

Perhaps not, but given the British variant has become so dominant globally it might test to breaking point Cambodia's efforts up until now. It is more contagious and virulent.

It was just odd that it was mentioned once and then silence.

Yes it is a bit odd. Maybe once they’d established it was here for sure there was no more need to keep doing lots of expensive sequencing tests to identify different strains.
They know the initial source of all the recent infections (the two Sokha escapees) so the variant will be the same for all cases at the moment.

They better be on the look out for the South African variant. If the latest study is to be relied on, anyone with an AZ vaccine is unprotected against it. No wonder the UK is closing her borders and having managed quarantine.
