A very interesting post on FB about Bali Herd immunity - not a specialist but some sound, logical thinking - worth a read:

My theory:
I strongly believe Bali has already developed “Herd Immunity”. The majority of Balinese have likely had or been highly exposed to Coronavirus and have developed antibodies and immunity to it.
We’ve travelled across the island and polled many people, there isn’t anyone here who knows a local Balinese person to have had Covid-19 or shows any symptoms at all since mid-March. There are only 10 people in isolation in the main hospital in Bali, mostly all imported cases.
Meanwhile, many are now reporting that Balinese and expats living here were extremely sick in January and February. But we’re healthy now.
What we need to prove that Bali has Herd Immunity:
1. We need the antibody test for all Balinese to show we’ve already been infected and have immunity.
2. If you can help fund this and get these tests here, we can coordinate and have all Balinese tested through our village Banjar system. We have 99% voter turn out because of our Banjar system.
3. With proven herd immunity, we can open Bali again slowly. With a new tourism that focuses on sustainability, environmental and cultural protection.
Facts:
1. Only 2 people (Foreigners) have died in Bali from Covid-19. The first on March 11. Our hospitals have only had total 89 cases, the majority being foreigners or imported from other parts of Indonesia.
2. We have 2.5 million Chinese Tourists in Bali each year, a huge percentage were in Bali from December 2019 (peak Christmas/NYE) right up until February 5, 2020 (Chinese New Year). 10,000 Chinese tourists remained in Bali during the height of Chinese New Year as they could not get flights back to China when Indonesia banned flights to/from China on February 5.
3. We had direct flights to Wuhan, China up until February 5, 2020.
4. After peak Christmas and NYE, my daughter went back to school on January 6. More than half her classmates were away sick! There were only 12 out of out 26 kids in her class for 2 weeks. Santi fell ill with a hacking cough where she could hardly breathe because she coughed so hard. She still had enough energy to go to school and no fever.
5. She says everyone in her class had this cough. It then passed to the ENTIRE high school, down to elementary school, teachers and parents. At that time, I researched it and determined it was “Walking Pneumonia”. This was January 10-20 timing.
6. China announced the existence of Coronavirus on January 23.
7. On January 27, our extremely good friend died. He was a 65-year-old Balinese male with poor health conditions. He died by not being able to breathe. Immediately following, we had days of massive cremation ceremonies of 10,000-15,000 people packed like sardines in Kerobokan.
8. In January, there was a huge uptick in older people dying in our village. We went to many more cremations at that time (late Jan/early Feb). As these were older people with underlying health issues, it wasn’t shocking or treated as Coronavirus. Nor did we have any ability to test for Coronavirus at that time.
9. From February 14-29, we went into 2 full weeks of island-wide ceremonies called Sugi, Galungan and Kuningan. 4,000,000 Balinese would be huddled together on the floors or bales at temples, drinking communal Holywater, touching each other and going home to their remote villages to stay with their families.
10. For Balinese people, nobody would ever go to the doctor for a dry cough and fever.
11. If old people who had heart, lung or diabetes died, we wouldn’t have though it unusual.
12. And we share EVERYTHING! Especially Holywater at Temple. Can you imagine how dirty that is? Twenty of us Priests make the Holywater in containers that have never been washed with soap, we add bits of offerings that others have made including bits of string and flowers to the water. These individual containers are combined into The Holywater which we them add tap water that’s been smoked and in a ceramic urn that also has never been washed in generations. When I bless people, I bless 100 people with this same water. I splash them and give them this water to drink 3 times.
13. Only 8% of the Indonesian population are over 65 so it's a young population, average age is 29.
14. 76% smoke, mostly men.
15. Our average temperature is 28-30 Celsius
16. 90% of Balinese live in open air family compounds without any air conditioning.
17. Balinese have super strong immune systems as their gut microbiomes are exposed to all sorts of bacterial, dirt, etc. Did you read point #11?
Next steps - please comment below if you can help here:
1. We need the antibody test for all Balinese to show we’ve already been infected and have immunity.
2. If you can help fund this and get these tests here, we can coordinate and have all Balinese tested through our village Banjar system. We have 99% voter turn out because of our Banjar system.
3. With proven herd immunity, we can open Bali again slowly. With a new tourism that focuses on sustainability, environmental and cultural protection.
