A man has died after he caught a horrific flesh eating bacteria when he chased his dog into a stagnant pool of water.
Jeff Bova, of San Diego, who was engaged to be married, died on Friday, a month after wading into the pond with a small cut on his right arm.
Now the 41-year-old's mum is urging people to take care.
Susan McIntyre has said her son was diagnosed with necrotising fasciitis, a grim disease that spreads quickly in the body and can cause death.
He picked up deadly infection in the mountains of Julian in San Diego County.
The infection eats into the body's soft tissues with symptoms including red or purplish areas of painful swelling appearing on the body followed by fever, fatigue and vomiting.
One in three people diagnosed with the infection die, the Centers for Disease Control and Prevention warn.
If symptoms present themselves, the CDC say: "See a doctor right away if you have these symptoms after an injury or surgery. Even though minor illnesses can cause symptoms like these, people should not delay getting medical care."
Ms McIntyre, 67 of El Cajon, California, said her son did not often visit the doctors.
She told NBC: “He developed these really nasty blisters, and he said that it felt … when his arm was oozing that it was acid coming down his arm."
He tried to suffer through the infection treating it with antibiotic cream but eventually relented and went to a hospital.
Despite this he died two days later, his mum said.
Paying tribute to her son, she said he was compassionate, selfless and a dog lover.
She had a warning to others to avoid a similar fate.
The mum said: “Stay away from standing water, especially after it rains, because there is just a ton of bacteria in it.
“If you get any kind of cut and it starts getting red, go to the doctor immediately — don’t wait."
The mum said her son was building her a wooden stove for her patio.
She said: “He was just within a couple of days of finishing it. Right before he passed, he told me he still had a job to finish for me.”
A 2019 report found climate change may be bringing the bacteria to previously unaffected waters.
The CDC warn to take particular care over cuts, scrapes, insect bites, puncture wounds and surgical wounds.
They also said people can get necrotizing fasciitis after blunt trauma.
This is just one more of "flesh-eating bacteria" North Americans have to worry about.
The rare bacteria, 'Vibrio vulnificus', which is commonly found in warm shallow waters above 64C, that kills one in five infected is spreading fast across the US east coast and infiltrating popular beaches as temperatures warm up.
Florida recorded 65 cases last year, which was double the amount compared to previous years, with infections growing from from 10 to 80 per year over the last three decades.
It is due climate change warming up the seas, according to scientists.
According to a study published in the journal Scientific Report on Nature.com, there were 1,100 people found infections with the bacteria and 159 deaths in the US.
