Valley Fever is caused by Coccidioides fungi, found in dry desert soils of California, Arizona, Texas, and Mexico.

Infection happens when fungal spores are inhaled during dust storms, farming, or construction work.

Not spread person-to-person.

🌡️ Section 2: Presentation (1:30 – 2:30)

Pulmonary symptoms: fever, cough, chest pain, fatigue, night sweats.

Skin signs: rash, erythema nodosum (painful red bumps).

Severe/disseminated disease: affects skin, bones, joints, or brain → meningitis.

Higher risk in pregnant women, immunocompromised, elderly, and certain ethnic groups.

🛡️ Section 3: Prevention (2:30 – 3:10)

Avoid dust exposure in endemic areas.

Wet soil before digging, wear N95 masks if working outdoors.

No vaccine available yet.

🔬 Section 4: Diagnosis (3:10 – 4:30)

Chest X-ray may show nodules or cavities.

Culture & histology: spherules with endospores (gold standard but dangerous to lab staff).

Serology is most commonly used: detects IgM and IgG antibodies.

Antigen tests and PCR are helpful in severe or disseminated cases.

💊 Section 5: Treatment (4:30 – 5:30)

Many mild cases resolve without treatment.

Antifungal therapy for moderate to severe cases:

Fluconazole (preferred) or Itraconazole.

Amphotericin B for severe disseminated disease.

CNS infection (meningitis): long-term fluconazole, often lifelong.

🧪 Section 6: Serological Markers Explained (5:30 – 6:40)

IgM (Tube Precipitin test):

Appears in 1–3 weeks → means recent/acute infection.

Declines after weeks to months.

IgG (Complement Fixation test):

Appears later, persists longer.

High titers indicate active or disseminated disease.

Rising titers → worsening.

Falling titers → recovery.

CF Titer significance:

less tha 1:2 = no significant disease.

1:2–1:16 = active pulmonary infection.

1:32 = likely disseminated.
