India does a high population density as well.
My sister lives there, so the truth about covid figures: She knows a lot of people who had covid (around 300+), only 4 got tested by Covid PCR , the rest - they got confirmed by other test but Covid test itself was avoided.
Why? If there were beds in the hospital in your area positive people were expected to go to hospital. The bills were in the range of £1500-£7000 depending if you were just given medicine (paracetamol and antibiotics) or oxygen, remedivisir . In India , most people don't have medical insurance, the covid bill was usually same as a major surgery. So people actively avoided the Covid Test. Small clinics , family GP usually confirmed Covid by symptoms, other blood test, lung function test, and sometimes by CT. These test usually cost around £70, and even if expensive then PCR test @£30 was still a way of isolating at home rather than a forced hospital treatment. If interested, read articles about how Indian govt had to intervene and fix cost of medical bills per day. Even so the cost were really high and if multiple people in a family were getting sick then it was simply not affordable. I have even heard stories about bribes given to testing people to make the results negative but it could be rumours.
Treatment at home - Indians are big on taking medication. You can get any medication from pharmacy without prescription 🙄. So with any suspected case in the household everyone was taking a combination of ivermectin (antiparasite) and Doxycycline (antibiotic) . It did have phycological effect and made them feel invincible. Also family doctors were freely giving ciplofloxin, hydrocholroquine, zinc, blood thinners to any suspect case. I think it was reckless but may be it helped save lives.
Overall , studying India is a waste of time because most figures are wrong. No one wants to get tested, they usually have mild covid , they have a chest full of covid medication so no one really cares that much about Covid, and if someone dies they have a funeral same day and no one gets a death certificate signed by a doctor.
