Now variants aside..
From the look of things, it's pretty obvious no matter how diligent we may be, observing the SOP.. The moment we remove our masks to eat, we turn vulnerable.. don't we ?
Wouldn't this explain, eg: latest 43 staff at Changi Airport positive #COVID19 ?
I will always remember this journal report abt cases amongst patrons at a Guangzhou restaurant back in Jan 2020.. Out of 83 customers at 15 tables, 10 were positive #COVID19 from 3 tables facing air-cond flow. Other 73 at tables elsewhere were negative wwwnc.cdc.gov/eid/article/26…
Hence we are sitting near, even if at 1m.. we are in proximity of aerosol from the index case nearby, we WILL GET infected.
If our loved ones came back from work.. infected by fellow workers at lunch table.. We WILL INFECT the family at home at the dinner table..
So it's pretty obvious, isn't it..
No Dine-in = Less Case.
Maybe a Research Model for a chi square test..
Null hypothesis:
Dine-in has no effect on #COVID19 case
A retrospective study. Just interview the current positive patients. Have a set cohort, say Px in Penang PKRC
Read this article dated 15th Dec 2020.. on how customers at restaurants are susceptible !! google.com/amp/s/www.forb…
The above article quotes from this journal publication by Kwon Keun-Sang et. al. .. jkms.org/DOIx.php?id=10…
Reading the article, you will realize that even at a distance of 2m.. in fact 4.8m & 6.5m to be exact !! Droplet aerosols can travel from index case and infect 2 others .. jkms.org/DOIx.php?id=10…
Hence it begs the question..
How many clusters in whole of Malaysia: work place or community or high risk or religious.. have had a collection of people eating together, even for 1 single occasion ?
Dine-in was the SINGLE COMMON FACTOR !!

Latest update: 1st Aug 2022, 10.45am.. Leaking Sewage @ Jln Masjid Negeri, near Autopont Flyover Bridge to Lam Wah Ee Hospital !! It's BAD !! @IwkComms in #Penang has been informed. #IWK ..
Now to the uninitiated.. @KKMPutrajaya has been putting out our #COVID19 data in a website called #CovidNow as below 👇🏻 ..
which gives a full range of info like vaccination rates, hospitalization data, case numbers etc .. #Malaysia .. 1/n covidnow.moh.gov.my
Nevertheless, current #COVID19 data in #Malaysia definitely shows a rising trend. I'm sure many amongst us are seeing cases in our friends, acquaintances, work colleagues, students, church family etc..
Is there a commonality in the present cases, especially the clusters ? .. 2/n
Taking present "official" 20 #COVID19 clusters in #Malaysia (I say "official" some obvious "clusters" were not reported eg: by JKN, in #Penang ) .. 🤔
Back to the "official" 20 clusters:
10 = Education 50%
8 = High Risk 40%
1 = Detention Centre 5%
1 = Workplace 5% .. 3/n
