Abstract:
During the 2015 Korean MERS outbreak, we experienced atypical presentations of MERS-CoV infections in three immunocompromised hosts that warranted exceptional management. Case 1 showed delayed symptom development after a four-day asymptomatic period, Case 2 experienced a 20-day incubation period, and Case 3 exhibited persistent viral shedding without clinical deterioration. Recognizing these exceptions is extremely important in the management of MERS-CoV-exposed or -infected patients and for control of potential MERS outbreaks.
Insights
Atypical Middle East Respiratory Syndrome Coronavirus (MERS-CoV) presentations occurred in immunocompromised patients during the 2015 Korean outbreak. Recognizing these MERS-CoV variations is crucial for patient management and outbreak control.
Area of Science:
- Infectious Diseases
- Virology
- Immunocompromised Host Research
Background:
- The 2015 Korean Middle East Respiratory Syndrome Coronavirus (MERS-CoV) outbreak highlighted the need to understand viral behavior in diverse patient populations.
- Immunocompromised individuals may present unique challenges in MERS-CoV infection diagnosis and management due to altered immune responses.
Observation:
- Three immunocompromised patients exhibited atypical MERS-CoV infection patterns during the 2015 outbreak.
- Case 1: Delayed symptom onset following a four-day asymptomatic incubation period.
- Case 2: An extended 20-day incubation period observed.
- Case 3: Persistent MERS-CoV viral shedding without significant clinical decline.
Findings:
- Atypical MERS-CoV presentations, including extended incubation and delayed symptom development, can occur in immunocompromised hosts.
- Persistent viral shedding without clinical deterioration was observed in one case, complicating transmission risk assessment.
- These variations underscore the complexity of MERS-CoV infection dynamics in vulnerable populations.
Implications:
- Early recognition of these atypical MERS-CoV presentations is vital for effective patient isolation and treatment strategies.
- Understanding these variations is critical for implementing robust public health measures to prevent and control MERS outbreaks.
- Further research into MERS-CoV pathogenesis in immunocompromised individuals is warranted to refine clinical guidelines.
