[One case of overseas imported quartan malaria].

Area of Science:

• Tropical Medicine
• Infectious Diseases
• Parasitology

Background:

• Quartan malaria is a significant global health concern, particularly in tropical regions.
• Imported cases pose a challenge to non-endemic areas, requiring accurate diagnostic capabilities.
• Long-term work in Africa increases the risk of exposure to malaria parasites.

Observation:

• A patient returning from Africa to Weihai City presented with malaria symptoms including fever, sweating, and headache.
• Initial diagnosis was confirmed through blood tests, microscopy, and PCR amplification.
• The patient had no history of blood transfusion or travel to endemic areas within China.

Findings:

• The case was identified as imported quartan malaria (Plasmodium vivax).
• Microscopic examination and PCR confirmed the diagnosis.
• The patient received a successful 8-day treatment regimen of chloroquine and primaquine.

Implications:

• This case underscores the need for heightened awareness and diagnostic preparedness for imported malaria in non-endemic regions.
• Effective treatment protocols can lead to complete patient recovery and prevent recurrence.
• Surveillance systems must be robust to detect and manage such imported infectious diseases promptly.
