Background: Although there is a rising trend in both dengue cases and immunocompromised conditions, there is limited research on how common severe dengue is in immunocompromised individuals. This data is key for those advising the ever-increasing numbers of immunocompromised travellers.
Methods: We conducted a systematic review and meta-analysis of studies reporting dengue frequency or outcomes in immunocompromised populations. Non-human and review articles were excluded. Risk of bias was assessed using the ROBINS-E tool.
Results: Eighty-five studies were included, 63 had a very high risk of bias. Frequency of dengue among different immunocompromised patient cohorts varied from 0.3%-6.3%. Of 1182 dengue cases, 664 had autoimmune diseases, 388 were post-solid organ transplant (SOT), 20 post-stem cell transplant (HSCT), 28 had haematological malignancies, 24 non-haematological malignancies, and 58 were HIV-positive. Severe dengue and mortality were estimated at 0.27 [0.22-0.33] and 0.14 [0.10-0.18], decreasing to 0.16 [0.09-0.27] and 0.04 [0.03-0.05] when very high risk or small-sample studies were excluded. Twenty-three (5.6%) of post-transplant dengue patients were considered as donor-related. Mortality reached 66.7% in HSCT and 10% in SOT. Dengue RNA was detectable up to four months in blood, and up to two years in urine; viable virus was isolated from urine at nine months.
Conclusions: Dengue in immunocompromised, especially HSCT, is associated with high severity and mortality. It also has the potential for prolonged viral persistence.

The multiple epidemics of Zika virus (ZIKV) posed a substantial threat to public health. Clinical evidence suggests that ZIKV could break through the blood-brain, blood-placenta, and blood-testis barriers, leading to severe outcomes such as congenital malformations in newborns and Guillain-Barré syndrome in adults. Currently, there are no specific treatments for ZIKV infection.

Mucormycosis is a rare, life-threatening opportunistic fungal infection with high mortality rates that primarily affects immunocompromised patients. The co-occurrence of dengue fever and mucormycosis is extremely rare, with only a few cases reported worldwide. We report a case of a 50-year-old female diagnosed with mucormycos following dengue fever.

Background: Dengue, a viral infection transmitted by mosquitoes, is a growing global health concern, particularly as its spread now puts half of the world's population at risk. While dengue usually resolves after the primary infection, persistent or chronic cases can occur in immunocompromised individuals.
Case Presentation: This case study reports a 43-year-old woman with lupus nephritis and end-stage kidney disease who experienced symptomatic dengue reactivation nearly three years after her initial infection.

Background: The clinical manifestations of dengue are well-described, but ocular involvement is being increasingly recognized and alterations to the natural trajectory of disease, including protracted viraemia, have also been recognized in immunocompromised patients. We describe a case of dengue in a lung transplant recipient which manifested predominantly as ocular symptoms following short-lived systemic features, and with protracted viraemia with delayed IgM to IgG seroconversion.
Case Presentation: A 40-year-old woman who had a bilateral lung transplant 15 years prior for cystic fibrosis presented with headaches, bilateral scotomata and rapidly deteriorating visual acuity.
