Novel entry inhibitors and replication inhibitors in trials
Monoclonal antibodies in early clinical investigation
Vaccine development
Virus-like particle vaccine in Phase 3 trials as of 2024
Live attenuated and recombinant vaccines in earlier stages
Analgesic strategy rationale
Dengue exclusion before NSAID use critical
Dengue co-circulation in chikungunya-endemic areas
NSAID-induced platelet dysfunction dangerous in dengue thrombocytopenia
Step-up analgesia aligned with WHO pain ladder
Acetaminophen first; NSAIDs second; weak opioids third
Corticosteroid use remains controversial
Short-course benefit for refractory subacute arthralgia
Rebound risk limits utility
Chronic disease management principles
Hydroxychloroquine evidence strongest for CHIKV chronic arthralgia
Anti-inflammatory and immunomodulatory mechanisms
Also used in lupus and RA for similar reasons
Methotrexate for erosive disease mimicking RA
Disease-modifying benefit; requires monitoring
Physical therapy integral to long-term recovery
Prevents contractures and muscle atrophy
Improves functional outcomes in chronic phase
Prevention and public health
Vector control measures
Eliminate standing water (mosquito breeding sites)
Insect repellent (DEET, picaridin, IR3535)
Long-sleeved clothing and bed nets
No prophylactic antiviral available
Travel advisory awareness in endemic zone travelers
Patient Discharge Instructions
copy discharge instructions
Chikungunya home care instructions
Rest during the fever phase
Limit strenuous physical activity until fever resolves
Gentle range-of-motion movements to prevent joint stiffness
Hydration
Drink 2 to 3 liters of fluids daily
Water, oral rehydration solutions, clear broths
Avoid alcohol which worsens dehydration
Pain and fever relief
Acetaminophen (paracetamol) as prescribed for fever and joint pain
Do not take aspirin or ibuprofen until your doctor confirms it is safe
Cold compresses on swollen joints for comfort
Rash care
Antihistamine tablet as prescribed for itching
Avoid scratching to prevent skin infection
Loose comfortable clothing over rash areas
Mosquito precautions to prevent spreading to others
You can pass the virus to mosquitoes while you have fever
Use insect repellent on exposed skin
Wear long sleeves and long pants indoors and outdoors
Sleep under bed nets if available
Eliminate standing water around your home
Buckets, flower pots, tires, clogged gutters
Change water in pet bowls and bird baths every few days
Warning signs to return to emergency
Difficulty breathing or chest pain
Confusion, unusual drowsiness, or seizure
Inability to drink fluids or keep any food down
Very high fever not improving with acetaminophen
Bleeding from gums, nose, or in stool or urine
Severe skin blistering or peeling
No urine output for 8 hours
Extreme weakness or inability to walk
Ongoing joint pain after fever resolves
Some joint pain may last weeks to months; this is expected
Continue prescribed pain medication as directed
Gentle exercise and physiotherapy help recovery
Return to clinic if joint pain persists beyond 3 months
Specialist assessment may be needed for chronic joint disease
Inform close contacts to watch for fever and joint pain
Mosquito exposure is the transmission route; not person-to-person
Follow-up instructions
See your family doctor within 48 to 72 hours
Blood tests may be needed to confirm diagnosis or check organ function
Report your travel history to your doctor for public health notification
