Weird news - Going crabbing and getting major infection

This is the kind of weird and tragic news that shakes people who believe that the environment around them is tame and most dangerous items have been controlled. It also tends to scare people (atleast a section of people would get scared enough to not go into water for fear of contracting something similar).
What happened in this case ? Well, this person went crabbing into a local river, something that is fairly common. However, soon after, the person started feeling a pain into one limb, which spread soon to the other limbs. This eventually developed into blisters all over, and when he got the infection checked out, this was apparently a bacteria that is present during summer months and can get into the body through even small cats. Health advisories can be issued but the situation is very common that it is difficult to prevent such infections from happening, even though they happen rarely (link to article):

The hospital said he developed Vibrio necrotizing fasciitis, a bacteria that lives in warm waters and can persist during the summer months. The bacteria can enter through even the smallest wound in the body. "We can only recommend that residents avoid entering brackish waters, especially if they have are immunocompromised or have open wounds or sores on their body," Hetzell highlighted. Brackish water is the combination of fresh and seawater often found in the area where rivers meet the sea. Indeed, Perez's daughter said another family member who swam in the area got skin rashes and painful swelling in one of her legs. Fortunately, she was given antibiotics right away. One of Perez' friends who went fishing in Matts Landing had a swelling as big as a baseball in one of his elbows.
