A three-year-old lioness rescued from war-torn Ukraine has undergone critical dental surgery to remove a severely infected canine tooth caused by an abscess.

Most patients experience a sudden onset of fever, headache, muscle aches, rash, and joint swelling within a few days of being bitten by an infected mosquito.

But since the introduction of powerful antiretroviral drugs in the 1990s that allow those infected to continue living healthy lives — and more recent preventative treatments such as PrEP — fatalities have plunged.

But, perhaps most notable, only about half of the 30,000 children infected with hepatitis B got it from their mothers; the other half contracted it through casual contact, likely from other household contacts.
