failed to ever contract infection. Contraction occurs overwhelmingly from skin exposure to any contaminated soil, contaminated potting soil, contaminated waters, lack of sanitation, or environmental factors as potential vectors. Nearly never to extraordinarily very rarely documented is transmission from person to person (besides from infected male homosexual sex), other than closeness of contact to the productive coughing of a very ill hyperinfected individual. It has been shown possible to occur in that situation, or potentially other similar scenarios, it is speculated via pulmonary secretions of a direly hyperinfected individual. In which case treatment for others may be indicated, if deemed necessary by proximity, symptoms, precautions, probable exposures to the same vectors, or through screening of serology and stool samples, until infection is eradicated. Before administering steroids at least somewhat screening for infection in even remotely potentially susceptible individuals in order to prevent escalating the infection is advised. As not doing so in certain cohorts can have extremely high mortality rates from inadvertently caused hyperinfection via immunosuppression of application of certain steroids. Thus extreme caution with respect to iatrogenic risks is crucial to avoiding deaths or other adverse consequences in treatment, that of course prefigures a correct diagnosis. People with high exposure to Strongyloides stercoralis may mitigate the risk of strongyloidiasis hyperinfection associated with corticosteroid treatment, with the presumptive use of ivermectin. Such hyperinfection has been a particular concern during the COVID-19 pandemic because of the use of corticosteroids for treatment of COVID-19 symptoms. The CDC and other international bodies recommend the use of ivermectin for refugees from areas which have a risk of strongyloidiasis. During the 1940s, the treatment of choice was enteric coated tablets of 60 mg gentian violet, three times daily, for 16 days. The cure rate was reported to be only about 50 to 70 percent, requiring repeat courses. It is possible the cure rate was even less than that published in the literature, due to the difficulty in positively diagnosing infection. Epidemiology Low estimates postulate it to affect 30–100 million people worldwide, mainly in tropical and subtropical countries, while higher estimates conservatively extrapolate that infection is upwards to or above 370 million people. It belongs to the group of neglected tropical diseases, and worldwide efforts are aimed at eradicating the infection. History The disease was first recognized in 1876 by the French physician Louis Alexis Normand, working in the naval hospital in Toulon; he identified the
