If you are wearing clothing head to foot all the time I expect you don't get much sun on you hence vitamin D deficiency.

One more point

The language point is odd. Presumably whatever news outlets are available at least mentioned the situation and anyone in a country which was suddenly shut down for four months would at least try to find out what was happening.

It's exactly right. The same reason the virus ripped through Spain and Italy. Multiple generations in the same house lead to it spreading.

Advice was given in all languages, but if you are less engaged with the main stream then maybe you were less likely to pick up on good information. Although, I find that hard to believe. Mosques have excellent support networks.

Cultural shame might have played a part. Peer pressure could be stronger in those communities.

Cardiovascular diseases are more prevalent in asian people. The impact of COVID-19 cant be proven, yet, but it is pretty likely to have a bigger effect.

Basically, it's a perfect storm and not really the governments fault.

Also, speaking to a care home owner at the weekend. Many families cant be bothered to look after their elderly relatives so chuck loads of money at a business to do it for them. When COVID-19 was rampant in nursing homes many of these people could have taken loved ones out, especially if they were working on furlough, but couldnt be bothered.
