The 2022 monkeypox outbreak presents atypical symptoms, particularly in individuals with HIV and herpes simplex virus type 2 coinfection. These complex cases highlight the potential for misdiagnosis of monkeypox during the global outbreak.
Area of Science:
- Epidemiology
- Infectious Diseases
- Virology
Background:
- The 2022 global monkeypox outbreak is characterized by atypical clinical presentations, differing from historical patterns observed in endemic regions.
- Concerns exist regarding sexual transmission and disease recognition, complicating public health responses.
- Individuals living with HIV may represent a vulnerable population with unique monkeypox manifestations.
Observation:
- Two cases of atypical monkeypox are presented in individuals with human immunodeficiency virus (HIV).
- Both cases involved coinfection with herpes simplex virus type 2 (HSV-2).
- Elevated troponin levels were noted in both patients, indicating potential cardiac involvement.
Findings:
- The presented cases demonstrate non-classical monkeypox symptoms, challenging initial diagnosis.
- Herpes simplex virus type 2 coinfection may alter the typical evolution of monkeypox cutaneous lesions.
- Atypical presentations underscore the difficulty in recognizing monkeypox in the current global outbreak, especially in immunocompromised individuals.
Implications:
- Clinicians must consider monkeypox in patients with atypical rashes, even in the context of HIV and other coinfections.
- Heightened awareness and diagnostic vigilance are crucial for timely monkeypox identification and management.
- Further research is needed to understand the impact of coinfections and underlying conditions on monkeypox clinical course.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
