A police officer died from tuberculosis that she got from a defendant who spat in her face.

On New Year’s Day, while Arina Koltsova, 35, was putting a man under arrest, the suspect spat in her face, according to the Daily Mail. At the time, she was unaware that the man had tuberculosis.

Koltsova was left untreated for a while until one day she passed out at work. After receiving a TB diagnosis, she began treatment.

Officer Mikhail Kindrakevich, her partner on duty, told the Daily Mail that she fell ill after New Year’s Day. “This man spat in her face after she had detained him. After a while, she passed out. She had been given medical attention. She lost a lot of weight, received chemotherapy, and was supplied food via an IV drip.

Two days after Koltsova passed away, he was buried in Kiev.

Koltsova’s police department posted on social media, “Favorite memories of Arina will remain in our hearts forever. This is an irreplaceable loss for the whole Kiev police.”

One of her friends wrote, “Arina wanted to change something for our country.” “She made the deliberate decision to join the police because she wanted things to improve.”

Antibiotics can be used to treat tuberculosis for six to twelve months, according to the National Institutes of Health. Drug resistance may exist in certain circumstances, making treatment difficult. It’s unknown if Koltsova had tuberculosis that was resistant to drugs or if her illness wasn’t identified in time for a successful course of therapy.

It is unclear if the suspect will be charged in Koltsova’s death.
