The spelling of the word "loasis" is not correct. The correct spelling of the word is "oasis". The IPA phonetic transcription of the word is /oʊˈeɪsɪs/. The first syllable is pronounced with a long "o" sound /oʊ/, followed by the diphthong sound /eɪ/ in the second syllable. The final syllable is pronounced with a short "i" sound /ɪs/. An oasis is a fertile area in a desert, often with a water source, and is a welcome respite for travelers.
Infestation with Loa (Filaria) loa, giving rise probably to the condition called Calabar swellings.
