How are the two connected? Well, you need ethyl alcohol to conduct tests for tuberculosis.
"With the alcohol ban imposed in Bihar, there is a severe scarcity of ethyl alcohol which is used to conduct tests for tuberculosis in government and private laboratories. The laboratories and hospitals are facing difficulties in procuring alcohol,”
It's amazing how such decisions to ban products are made - purely out of popular choice without really thinking about its long term impact. Not that alcohol ban was a bad idea, but really thinking through the use-cases helps.
Hope other state governments are learning from all this.
