A rarefied but potentially serious epenthetic infection spread by racoon has been line up in Los Angeles . This hebdomad , LA public wellness official report that at least two residents have been infested byBaylisascaris procyonis , more manifestly have intercourse as the raccoon roundworm . The worms can potentially stimulate severe neurologic and eye harm .
Baylisascarisworms will usually stick to one major carnivore host , but can infect other hosts , which lean to be prey . As their name allude to , raccoon ( Procyon lotor ) are the primary host ofB. procyonis . The worms will reach a racoon ’s gut , checkmate , and lie eggs that get pooped out by the critter into the extraneous public ( thankfully for the raccoon , the infection mostly does n’t make them fed up ) . The eggs will then modernise into infectious larvae ( still encase inside a protective shell ) , which can take two to four weeks .
From there , the larvae will unremarkably either be take by another racoon , ripe , and begin a new life cycle , or be eaten by diminished prey fauna like rodent . Even a slender detour is n’t necessarily the end for the worm , since they can envelop themselves into stout cysts that get buried in the animal ’s tissues ; should the prey later be eat by raccoons , the worms can emerge and proceed with business as usual . But thing get a little more complicated whenpeople or our petsare ill-starred enough to get infected by these louse .

On Wednesday , the Los Angeles County Department of Public Healthannouncedthat it was investigate two human cases ofB. procyonisinfection , both of which occurred in the South Bay arena of Los Angeles County . Though the functionary did not provide any item on the condition of these two victims , they noted that these infections can be a serious matter .
While raccoons are the dirt ball ’s primary host , dogs can play the part well enough , as they can be infected byB. procyonislarvae and successfully server adult dirt ball that will slough egg back into the public . But humans ( and cats for that matter ) are complete dead remnant for the insect larvae when we get infected by them . regrettably for us , the larva can still grow bigger and will sometimes transmigrate to our internal organs , eyes , or brain , induce serious havoc . Human cases of baylisascariasis are rare , but can be life - minatory when this pass off . According to the Centers for Disease Control and Prevention , only a few dozen case in full have beendocumentedin the U.S. , but of the 23 known cases with neurological legal injury , as of 2018 , six have died .
A turgid pct of raccoons in the Western U.S. are thought to carryB. procyonis(up to 82 % , according to some estimates ) , and the infective larvae can survive in the environment for years , according to the CDC . leave that raccoons thrive by living near humans , the risk ofB.procyonisis certainly ever present , if pocket-sized . LA officials say that younger children , hoi polloi with developmental disabilities , and those with pica ( an eating disorder where people run through thing that are not typically considered nutrient ) are at higher danger for these transmission , since they ’re more likely to put polluted fingers , filth , objects , or feces into their mouths . But people can take vernacular sense guard to lower their betting odds of catching these nasty worms .
