Leptospiroz (Maladi Weil a) Apre Wated nan dlo inondasyon oswa dlo dous: je wouj san pi, doulè ti towo bèf, ak lajònis¶

Lè yon siklòn, yon mouason, yon inondasyon, oswa yon rezèv egou fè lari ak sousòl katye yo tounen dlo mawon ki byen fon jenou - oswa lè yon naje, kayakè, triatlèt, kiltivatè, oswa kous avanti k ap pase nan rivyè dlo dous cho, kanal, oswa labou mouye ki kontamine ak pipi rat, sourit, chen, mamifè sovaj,, mikwoskopik oswa bèt sovaj. Bakteri ki gen fòm tire lyèj ki rele Leptospira interrogans ka pèse tou dwat nan po dlo adousi, ti grate, oswa manbràn mikez yo nan je, nen ak bouch. Si yon moun devlope yon lafyèv ki wo toudenkou, frison tranble, maltèt fwontyè/retwo-orbital batman, gwo doulè nan ti towo bèf yo ak nan do ba yo, ak je wouj klere SAN pi kolan (conjunctival suffusion) anywhere from 2 to 30 days (typically 5 to 14 days) apre dlo inondasyon oswa kontak dlo dous - oswa pwogrese nan ** po/zye jòn-zoranj (jaundice), pipi ki gen koulè nwa te oswa ki pa gen anpil, senyen nan nen, oswa touse san (Weil's Disease)** - rele nimewo ijans lokal ou a atravè nou an nimewo ijans anyè oswa ale nan yon Depatman Ijans lopital imedyatman. Epitou konsilte gid nou yo sou Vibrio vulnificus ("manje vyann" enfeksyon dlo lanmè cho), Sendwòm Pulmonè Hantaviris ki soti nan jete wonjè, blesi nan ren egi, rabdomiolyz, ak triyaj pipi nwa, ak sepsis ak rekonesans chòk septik.

Dapre ** Òganizasyon Mondyal Lasante (WHO)**, Sant pou Kontwòl ak Prevansyon Maladi (CDC), ak Oganizasyon Sante Panameriken an (PAHO), leptospiroz se maladi bakteri zoonotik ki pi gaye sou Latè, ki enfekte plis pase 1.03 million people ak sa ki lakòz 58,900 deaths chak ane - ak epidemi masiv apre siklòn ak apre inondasyon dokimante atravè Puerto Rico, Florid, Awayi, Texas, Wayòm Ini, Ewòp kontinantal, Brezil, End, Filipin, Japon, ak nò Ostrali. Paske premye faz leptospiroz la sanble ak lafyèv deng, grip, oswa yon maladi viral woutin, pasyan yo souvan rate fennèt Oral Doxycycline oswa Azithromycin.Days 1 to 5), sanble refè pou 1 a 3 jou, epi answit tonbe nan Faz 2 Leptospiroz Icteric (Weil's Disease) oswa Sindwòm Emoraji Leptospiral Pulmonè (LPHS), kote mòtalite monte soti < 1% jiska 10% to 50%+ akòz konbine ki pa oligurik/oligurik echèk ren egi, ipèbilirubinemi konjige (orange jaundice), tronbositopeni, ak masif senyen alveolè nan poumon. Rekonèt de siy egzamen fizik bò kabann yo (Conjunctival Suffusion + Severe Calf Squeeze Tenderness) ak divilge ekspoze dlo inondasyon ou imedyatman debloke terapi antibyotik gerizon.

Fè sa kounye a¶

1. Si w devlope yon gwo lafyèv toudenkou (>= 38.5 C / 101.3 F), frison, gwo maltèt, ak doulè nan misk anndan an 2 to 30 days nan pated nan dlo inondasyon, netwaye yon sousòl ki inonde, naje nan yon lak/rivyè, oswa manyen fèm/pipi bèt kay: ale nan yon doktè oswa ale nan yon lopital Depatman Ijans JODIA ak divilge klèman ekspoze dlo ou / inondasyon. Kòmanse oral Doxycycline (100 mg twice daily for 7 days) oswa Azithromycin (500 mg daily for 3 days) pandan 5 premye jou yo rapidman efase spirochèt yo nan san an epi anpeche pwogresyon nan maladi Weil ki menase ògàn yo.
2. Gade blan je w nan yon glas (sclera/conjunctiva) epi dousman peze misk ti towo bèf janm ou yo (gastrocnemius):
3. Siy #1 (Conjunctival Suffusion): Èske blan tou de zye yo wouj klere ki vin wouj ak wouj ak veso sangen ki dilate, SAN pi kolan jòn, san kwout oswa demanjezon? Sifizyon konjonktif rive nan jiska 55% nan ka leptospiroz (appearing on Days 3 to 4) epi li nòmalman pa janm wè nan grip òdinè, malarya, oswa tifoyid.
4. Siy #2 (Severe Calf & Lumbar Myalgia): Li senpleman manyen oswa peze do ti towo bèf ou oswa peze sou do ou (erector spinae) lakòz entans, tandrès wincing? Konbinezon sa a (Fever + Flood/Freshwater Contact + Red Eyes Without Pus + Severe Calf Pain) se tetrad dyagnostik klasik nan leptospiroz egi.
5. Rele 911 / 112 / 999 / 000 oswa ale nan yon Depatman Ijans Lopital IMEDYATMAN si NENPÒT Faz 2 "Maladi Weil" oswa Drapo Wouj Emoraji parèt (often after a deceptive 1-to-3-day dip in fever around Day 5 to 7):
6. Jòn oswa koulè zoranj klere nan blan je yo oswa po (Jaundice),
7. ** Diminye pwodiksyon pipi (not urinating for > 8 hours) oswa pipi nwa mawon/koulè te**,
8. ** Touse san (hemoptysis), krache woz ki mouye, oswa souf kout toudenkou (Leptospiral Pulmonary Hemorrhage Syndrome - 50%+ mortality)**,
9. Eksize tach po wouj/vyolèt (petechiae), jansiv ki senyen, senyen nan nen, oswa poupou nwa goudron, OSWA
10. ** Kou rèd, fotofobi grav (light hurts eyes), konfizyon, oswa batman kè iregilye (aseptic meningitis or myocarditis)**.
11. Di mo egzak sa yo bay Enfimyè ak Doktè Triyay Sal Ijans yo nan premye 30 segonn yo: "I waded in floodwater / freshwater ___ days ago and now have fever, calf pain, and red eyes/jaundice. Please evaluate immediately for Leptospirosis / Weil's Disease, start IV Ceftriaxone (or IV Penicillin G / Doxycycline), and check serum Creatinine, Potassium, Bilirubin, CPK, Platelets, and a Chest X-Ray."
12. ** EVITE ibipwofèn (Advil/Motrin), Napwoksèn (Aleve), Aspirin, ak lòt soulaje doulè NSAID si ou gen lafyèv apre dlo inondasyon oswa ekspoze twopikal.** Tou de Leptospiroz ak Lafyèv Deng lakòz gwo gout plakèt (thrombocytopenia) ak agi blesi nan ren entèrstisyal: pran NSAID bloke prostaglandin ren yo (precipitating complete kidney shutdown) ak paralize rès plakèt (triggering fatal gastrointestinal or lung hemorrhage). Sèvi ak dòz asetaminofèn/parasetamol sèlman avèk prekosyon SÈLMAN si yon doktè te elimine fonksyon fwa/lajònis, oswa itilize twal refwadisman fizik jiskaske yo evalye.
13. (wellingtons) oswa waders nan pwatrin** ak gwo gan ki enpèmeyab kawotchou/nitrile, kouvri chak ti koupe oswa pike moustik ak yon bandaj idrokoloid/Tegaderm ki enpèmeyab, epi lave po ak savon ak dlo pwòp imedyatman apre kontak.

Part 1: How Leptospira Enters the Body (And Why You Do Not Need an Open Cut to Get Infected)¶

1. The Corkscrew Spirochete and the Urban/Rural Rat Reservoir¶

Leptospira interrogans (with over 250 pathogenic serovars, notably *Icterohaemorrhagiae* carried by brown rats, *Canicola* in dogs, *Pomona* in pigs and cattle, and *Hardjo* in cattle) is a tightly coiled, aerobic spirochete bacterium with hooked ends that spins around its axial filaments like a motorized corkscrew. - How Rats and Mammals Seed Floodwater: Chronically infected brown rats (Rattus norvegicus), roof rats, mice, livestock, and unvaccinated dogs harbor Leptospira permanently inside their renal proximal convoluted tubules without appearing sick, shedding millions of live spirochetes per milliliter of urine. - Environmental Survival in Water and Mud: While Leptospira dies quickly on dry, sun-baked pavement or in high-salinity ocean water, in warm, neutral-to-slightly-alkaline freshwater (pH 6.8 to 7.6, temperatures 20 to 32 degrees Celsius / 68 to 90 degrees Fahrenheit), standing floodwater, damp soil, and post-hurricane mud, Leptospira remains alive and infectious for weeks to several months.

2. The Four Portals of Human Entry (Including Waterlogged "Pruney" Skin)¶

Unlike many bacteria that require a deep puncture wound to cross the skin barrier, Leptospira's corkscrew motility and outer-membrane collagenase/hyaluronidase enzymes allow it to enter the human bloodstream through four distinct portals: 1. Microscopic Cuts, Scrapes, Mosquito Bites, or Abraded Shins: Even a 1-millimeter scratch from grass, rubble, or boots lets thousands of spirochetes directly into dermal capillaries. 2. Water-Macerated ("Waterlogged / Pruney") Intact Skin: When a resident or rescue worker wades in floodwater or wears wet, flood-soaked socks and sneakers for more than 30 to 60 minutes, the outer stratum corneum layer of skin swells and softens (maceration), allowing Leptospira to bore straight through intact, unbroken waterlogged skin. 3. **Konjonktif (Eyes(while clearing storm drains or pressure-washing a flooded garage - NEVER pressure-wash flood mud without unvented goggles and an N95 mask) oswa siye figi ou ak men mouye gan inoculate konjonktiv la dirèkteman. 4. Vole Dlo Kontamine: Gòlf dlo rivyè oswa lak pandan naje, chavire yon kayak, oswa bwè dlo pi ki kontamine ak inondasyon.

Pati 2: De siy klasik bò kabann yo ak delè klinik bifaz la¶

Paske seroloji laboratwa (Tès aglutinasyon mikwoskopik / MAT ak IgM ELISA) pa vin pozitif jiskaske Jou 5 a 10 nan maladi, doktè ijans fè dyagnostik leptospiroz egi nan kabann nan lè yo rekonèt de siy fizik patognomonik li yo ak kou klinik bifaz li yo:

1. De endikasyon fizik Hallmark yo (Conjunctival Suffusion + Gastrocnemius Myalgia)¶

+-------------------------------------------------------------------------+
|  HOW TO SPOT LEPTOSPIROSIS AT THE BEDSIDE IN 60 SECONDS                 |
|                                                                         |
|  1. CONJUNCTIVAL SUFFUSION (RED EYES WITHOUT PUS - DAYS 3 TO 4):        |
|     - Pull down the lower eyelid and look at the bulbar and palpebral   |
|       conjunctiva (the covering over the white of the eye).             |
|     - In Leptospirosis, spirochetal vasculitis dilates the pericorneal  |
|       and conjunctival blood vessels, turning the eyes BRIGHT RED OR    |
|       PINK-ORANGE (often with subconjunctival hemorrhages) - character-   |
|       istically WITHOUT purulent yellow discharge, sticky eyelids, or   |
|       itching (unlike viral or bacterial pinkeye).                      |
|                                                                         |
|  2. EXCRUCIATING CALF & LUMBAR TENDERNESS (RHABDOMYOLYTIC MYOSITIS):    |
|     - Leptospira directly invades skeletal muscle fibers, causing       |
|       focal myofibrillar necrosis and elevated Creatine Kinase (CPK).   |
|     - Gently squeezing the patient's CALF MUSCLES (gastrocnemius),      |
|       thighs, or lower back muscles elicits disproportionate pain       |
|       (patients often say walking feels like their calves were beaten   |
|       with a baseball bat), and abdominal wall myalgia can mimic an     |
|       acute surgical abdomen.                                           |
+-------------------------------------------------------------------------+

2. Klasik delè bifaz la (Phase 1 Septicemic vs. Phase 2 Immune / Weil's Disease)¶

• Peryòd enkibasyon: 5 to 14 days apre kontak dlo/labou (full range: 2 to 30 days).
• Faz 1: Faz egi Leptospiremic (Septicemic) (Lasts 4 to 7 Days):
• Spirochèt Leptospira vivan ap sikile nan tout san ak likid serebrospinal la (CSF).
• Aparisyon brid sou kou gwo lafyèv (39 to 40 C / 102 to 104 F), gwo maltèt retro-orbital/frontal, fotofobi, **myalji grav nan ti towo bèf ak anba do **, sifizyon konjonktival, kè plen, vomisman, dyare, ak detanzantan yon gratèl makilè/petèk pasajè sou shin yo ("pretibial fever").
• Remak pou dyagnostik: Pandan Jou 1 a 7, San ak CSF an tan reyèl PCR POSITIF, pandan tès antikò (IgM) ka toujou negatif.
• Danje entèfaz 1-a-3-jou a (Around Day 5 to 8):
• Lafyèv desann nan nòmal epi pasyan an santi l pi byen pandan antikò yo retire spiwochèt nan san an (though spirochetes now hide in the kidney tubules and begin shedding in the urine). 85% to 90% nan ka modere "anikterik" refè pou tout tan apre yon ti repitasyon tou kout nan tèt fè mal.
• ** Faz 2: Faz iminitè a ak Maladi Icteric Weil a (Starts Day 6 to 10 and Lasts Weeks):**
• Nan 10% to 15% nan pasyan (espesyalman moun ki enfekte ak serovar Icterohaemorrhagiae oswa moun ki pa t resevwa antibyotik bonè), Faz 2 eklate kòm Maladi Weil (the classic triad of **Orange Jaundice + Acute Kidney Injury + Hemorrhage**) ak/oswa Sindwòm Emoraji Pulmonè Leptospiral (LPHS)*:
  1. ** "Orange lajònis" nan Maladi Weil a (Cholestatic Hepatic Dysfunction Without Massive Liver Necrosis):**
  2. Je ak po pasyan an vire yon yon jòn-zoranj ki frape (rubinic icterus) kòm serom bilirubin konjige monte nan 15 to 40+ mg/dL (because bright red conjunctival suffusion + yellow scleral icterus = orange eyes), poutan transaminaz fwa (AST and ALT) yo sèlman yon ti kras elve (typically 100 to 250 U/L, raman > 500 U/L), ki imedyatman distenge maladi Weil a ak epatit viral egi A/B/E (where AST/ALT exceed 1,000 to 3,000 U/L).
  3. Ipokalemik inik ki pa oligurik -> blesi ren egi oligurik (AKI):
  4. Pwoteyin manbràn ekstèn Leptospira dirèkteman anpeche Na+-K+-2Cl- (NKCC2) kotranspòtè nan branch monte epè Henle ak domaje tib proximal la.
  5. Kòm yon rezilta, ensifizans ren leptospiral bonè se inikman ki pa oligurik ak gaspiye potasyòm (causing normal or LOW blood potassium / hypokalemia malgre kreyatinin k ap monte) - anvan rapidman pwogrese nan oligurik/anurik nekwoz tubulèr egi (ATN) ak ipèkalemia ki menase lavi, uremi, ak èdèm poumon ki mande emodyaliz ijan.
  6. Sendwòm Emoraji Leptospiral Pulmonè (LPHS - Kòz #1 nan lanmò rapid):
  7. Blesi toksin iminitè-medyatè kase louvri manbràn alveolatè sousòl kapilè yo atravè tou de poumon, sa ki lakòz emoraji alveolatè difize (DAH). Pasyan yo devlope toudenkou dispne, takipne, ipoksi, enfiltre alveolè patch bilateral sou radyografi pwatrin yo, ak emoptiz (coughing up bright red blood), ki ka lakòz asfiksi ak lanmò nan 24 a 48 èdtan menm nan pasyan ki poko vin lajònis.

Pati 3: Tablo Dyagnostik Diferans Mèt: Imite Post-Inondasyon ak Lafyèv Twopikal¶

Apre yon tanpèt twopikal, mouason, oswa inondasyon, sal dijans yo wè ogmantasyon Leptospiroz, Lafyèv Deng, Malarya, Typhoid, Hantavirus, ak Vibrio Sepsis an menm tan. Konpare anprent klinik ak laboratwa yo:

Pati 4: Tretman Lopital, Avètisman Jarisch-Herxheimer, ak Prevansyon Netwayaj Inondasyon¶

1. Premye liy rejim antibyotik (CDC / WHO Guidelines) ak Kilè pou kòmande chak tès¶

1. ** Distribisyon tès dyagnostik yo (Why Blood PCR Works in Week 1 and Urine PCR/IgM Works in Week 2):**
2. ** Jou 1 a 7 nan Lafyèv (Phase 1):** Lòd San antye (ak CSF) Leptospira PCR an tan reyèl (positive from Day 1 before antibodies exist) plis yon debaz Echantiyon serom IgM ELISA / MAT.
3. Jou 7 Avan (Phase 2 / Weil's Disease): Spirochèt disparèt nan san epi deplase nan ren yo; lòd Pipi Leptospira PCR plis Serom Anti-Leptospira IgM ELISA ak tès aglutinasyon mikwoskopik konvalesans (MAT).
4. Seleksyon Antibyotik Curative:
5. Leptospiroz anikterik pou pasyan ekstèn modere a modere:
   • Granmoun (ki pa ansent): Doxycycline oral 100 mg de fwa pa jou pou 7 days (Bonis: Doxycycline ansanm geri enfeksyon rickettsial ko-endemic tankou Scrub Typhus, Murine Typhus, ak lafyèv takte), OSWA Oral Azithromycin 500 mg yon fwa chak jou pou 3 days, OSWA Amoksisilin Oral 500 mg twa fwa pa jou pou 7 days.
   • Fanm Ansent ak Timoun < 8 Years: Azitromisin oral (10 mg/kg Day 1, then 5 mg/kg/day Days 2-3) oswa Amoxicillin (50 mg/kg/day divided TID).
6. Leptospiroz grav entène lopital / Maladi Weil / Emoraji poumon:
   • ** Ceftriaxone nan venn (1 to 2 grams IV every 24 hours for 7 days)**, OSWA penisilin G nan venn (1.5 million units IV every 6 hours for 7 days), OR Intravenous Cefotaxime (1 gram IV every 6 hours), OR Intravenous Doxycycline (100 mg IV every 12 hours).

2. Watch for the Jarisch-Herxheimer Reaction (2 to 6 Hours After the First Antibiotic Dose)¶

Because Leptospira is a spirochete (related to the bacteria that cause syphilis and Lyme disease), administre premye dòz bakterisid Penisilin G oswa Ceftriaxone lakòz dè milyon de spirochèt lyse an menm tan, jete lipoprotein endotoxin ki sanble nan san an: - Nan 1 to 6 hours nan premye dòz antibyotik la, pasyan an ka fè eksperyans yon brid sou kou Reyaksyon Jarisch-Herxheimer: gwo souke vyolan, yon 1 to 2 C ogmantasyon nan lafyèv, woujè, takikardi, ak yon ** gout toudenkou nan san presyon (hypotension)**. - Règ kritik: Yon reyaksyon Jarisch-Herxheimer se PA yon reyaksyon alèjik ak penisilin/ceftriaxone. Doktè yo dwe pa janm sispann antibyotik ki sove lavi a; olye de sa, yo kontwole pasyan an nan ER / ICU ak sipòte san presyon ak pridan kristaloid nan venn ak vasopressor pandan y ap reyaksyon an rezoud sou 12 a 24 èdtan.

3. Èske w ka pran antibyotik prevantif (Chemoprophylaxis) Si yo oblije mache nan dlo inondasyon?¶

• Kovèti pou Pwoteksyon Pèsonèl Vini Premye: Mete bòt kawotchou entak jiska jenou, gan ki enpèmeyab, ak gwo linèt anpeche > 90% nan ekspoze dlo inondasyon.
• ** Pwofilaksi Pre-/Aprè Ekspozisyon Doxycycline a Kout tèm (CDC / WHO Guidance for High-Risk Responders** Pou pèsonèl militè yo, ekip sovtaj dlo rapid yo, oswa rezidan yo inevitableman kap pase nan dlo inondasyon ki enfekte ak rat pandan yon epidemi aktif apre siklòn, esè klinik owaza demontre ke Doxycycline oral. 200 mg pran yon fwa pa semèn (two 100-mg capsules taken together once a week with food and a full glass of water) pandan peryòd ekspoze dlo inondasyon ki gen gwo risk diminye siyifikativman maladi leptospiroz nan klinik.

Nimewo ijans rejyonal yo ak pwotokòl ajans yo¶

Leptospiroz se yon maladi enfektye ki dwe notifye nan nivo nasyonal atravè gwo jiridiksyon sante piblik:

• Etazini (ki enkli Pòtoriko, Zile Vyèj Ameriken yo, Awayi, Florid, ak Gòlf/Kot Atlantik):
• Dispatch Ijans: Rele 911 pou nenpòt lafyèv apre inondasyon ki akonpaye pa lajònis, souf kout, touse san, oswa pwodiksyon pipi diminye.
• Sante Piblik ak Konsèy pou Laboratwa: Jere anba CDC Bakteri Espesyal Patojèn Branch (bspb@cdc.gov / Sant Operasyon Ijans CDC 770-488-7100), ki fè referans MAT seroloji ak lipL32 PCR an tan reyèl.

Kesyon yo poze souvan¶

Ki jan "konjonktivit" sanble, ak ki jan li diferan de pinkeye regilye (konjonktivit)?¶

**Sifizyon konjonktiv** se youn nan endikasyon ki pi serye sou kabann pou leptospiroz, ki parèt alantou 3 oswa 4 jou lafyèv. Lè w gade blan je pasyan an, ti veso sangen ki nan konjonktiv la anfle epi yo wouj klere oswa woz-zoranj (`often most intense around the edges of the cornea`), **men kontrèman ak pinkeye viral oswa bakteri (`conjunctivitis`), gen ZEWO kolan jòn/vèt pi, ZEWO limyèl kwout nan maten an, epi pa gen demanjezon grav**. Lè lajònis devlope nan Faz 2 (`Weil's disease`), konbinezon veso sangen wouj konjonktival yo sou yon skleros jòn bay je yo yon **eklere zoranj klere**.

Poukisa li tèlman danjere pou w pran Ibipwofèn (Advil), Naproxen (Aleve), oswa Aspirin pou lafyèv ak doulè ti towo bèf apre w fin pate nan dlo inondasyon?¶

De karakteristik leptospiroz ki menase lavi (`as well as dengue fever, which often circulates at the same time after tropical storms`) se **blesi nan ren egi (`interstitial nephritis and tubular damage`)** ak ** jete plakèt san yo (`thrombocytopenia`)**. Pran Medikaman Anti-enflamatwa ki pa Estewoyid (`NSAIDs like ibuprofen, naproxen, diclofenac, or aspirin`) konstrikte veso sangen aferan yo ki bay ren yo - sa ki ka pouse yon ren ki enfekte nan **ensifizans ren egi** - pandan y ap bloke fonksyon koagulasyon plakèt yo, ki ka deklanche **emoraji nan poumon fatal (`hemoptysis`) oswa vant senyen**. Toujou chèche evalyasyon medikal pou antibyotik vize (`Doxycycline or Azithromycin`) anvan ou pran soulaje doulè.

Èske mwen ka trape Leptospiroz nan men pwòp chen bèt kay mwen menm si pa te gen okenn inondasyon?¶

**Wi.** Chen domestik ka kontra *Leptospira* (`serovars Canicola, Grippotyphosa, Pomona, or Icterohaemorrhagiae`) lè w bwè nan flak lakou, etan oswa zèb mouye kote rat sovaj, raton, opossum, oswa mouftè te pipi. Menm si chen an sanble sèlman yon ti kras malad (`or after it recovers`), li ka jete bakteri *Leptospira* vivan nan pipi li pandan plizyè semèn. Si ou netwaye pipi chen andedan kay la ak men ou oswa si ou gen koupe nan men ou, ou ka vin enfekte. Toujou mete gan kawotchou/nitril lè w ap netwaye pipi bèt kay, lave men yo byen ak dlo ak savon, epi mande veterinè w la pou chak ane **Vaksen Leptospiroz Canine 4-serovar**.

Poukisa lafyèv pasyan an te ale pandan de jou epi apre sa te tounen gwonde ak je jòn ak pipi nwa?¶

Sa se klasik **bifaz ("de-faz") pèlen leptospiroz**. Pandan ** Faz 1 (`Days 1 to 7`)**, bakteri yo sikile nan san an, sa ki lakòz gwo lafyèv, frison, je wouj, ak doulè ti towo bèf. Anviwon jou 5 a 7, sistèm iminitè a pwodui antikò ki retire bakteri yo nan san an, kidonk **lafyèv la desann yon ti tan nan nòmal pou 1 a 3 jou**. Lè sa a ** Faz 2 (`the Immune Phase`)** kòmanse: nan ka grav (`Weil's Disease`), enflamasyon entans iminitè-konplèks frape fwa a, ren, ak poumon, sa ki lakòz toudenkou ** lajònis (`yellow/orange eyes`), echèk ren (`scant or dark tea urine`), menenjit, oswa touse san**. Pa janm sipoze yon lafyèv apre inondasyon fini jiskaske yon doktè trete li ak yon kou konplè nan antibyotik.

Èske dlo sale lanmè pote Leptospira?¶

*Leptospira* spirochèt yo se **òganis dlo dous ak tè imid**: yo pa ka siviv pou lontan nan dlo lanmè lanmè ki gen anpil fòs ak salinite (`35 parts per thousand`). **Sepandan**, apre gwo lapli oswa siklòn sou bò lanmè yo, ekoulman dlo dous ak drenaj tanpèt yo vide ekoulman kontamine ak pipi rat nan **bay kòt yo, bouch rivyè yo, estuary, plaj, ak dlo inondasyon nan lari salmatè**, kote tou de **dlo dous *Leptospira*** ak **marin. [*Vibrio vulnificus*](hemorrhagic-bullae-vibrio-vulnificus-warm-seawater-wound-infection-and-raw-oyster-septicemia-in-liver-disease.md)** ka enfekte natasyon ak sivivan inondasyon an menm tan.

Gid sa a bay enfòmasyon edikatif medikal pou ijans epi li pa ranplase swen ijans lopital pwofesyonèl, evalyasyon maladi enfeksyon, oswa jesyon nefroloji/ICU. Paske maladi Weil la ak emoraji poumon leptospiral ka lakòz ensifizans ren rapid ak arè respiratwa, nou rekòmande seryezman pou w pran yon premye swen pratik ak kou CPR ki sètifye nan men Lakwa Wouj, Anbilans St John, oswa yon founisè fòmasyon lokal ki akredite.
