America is running short on four key antibiotics and respiratory drugs for children, as seasonal bugs come back with a bang after being suppressed during lockdowns. Health officials have declared a shortage of amoxicillin, a vital antibiotic used to treat bacterial infections such as pneumonia, respiratory infections and strep throat. But doctors on the ground are also reporting dwindling stocks of Augmentin - a antibiotic drug that uses amoxicillin alongside clavulanic acid - Tamiflu, the most commonly used flu medication in US hospitals, and albuterol, an inhaler for asthma and to relieve other lung symptoms.
