“…The CPA 5‐year prevalence was about 77,502 cases after taking into account the annual expected deaths among those survivors over the course of 5 years. The total prevalence of CPA was anticipated to be 115,675 cases by adding the 33% of cases that are unrelated to TB 16‐20 …”

“…In the current estimate of invasive aspergillosis (IA), besides leukaemia, organ transplant and COPD hospitalisation, we added risk factors of haematopoietic stem cell transplantation (HSCT), lung cancer and HIV/AIDS‐related death into the calculation. Chronic pulmonary aspergillosis (CPA) incidence was estimated based on combination of misdiagnosed cases, CPA cases arising within 12 months of TB diagnosis or subsequent years plus 33% additional cases, for those not linked to TB (based on international reports) 16‐20 . The method for estimating allergic bronchopulmonary aspergillosis (ABPA) and severe asthma with fungal sensitisation (SAFS) remained unchanged from 2015, except the denominator numbers for adult asthma cases were updated to reflect local reports 8,21 …”

“…The total prevalence of CPA was anticipated to be 115,675 cases by adding the 33% of cases that are unrelated to TB. [16][17][18][19][20] Allergic bronchopulmonary aspergillosis was first described in Vietnam in 2016. 37 Using international data, indicating that typically around 2.5% of adult asthmatics have ABPA, we estimated 74,658 cases per year.…”

Background Anecdotally, the burden of fungal diseases in Vietnam is rapidly rising, but there has been no updated estimate on this issue since a previous report in 2015. Objectives In this study, we aimed at estimating the incidence and prevalence of serious fungal infections for the year 2020. Methods We made estimates with a previously described methodology, using reports on the incidence and prevalence of various established risk factors for fungal infections from local, regional or global sources. Results We estimated 2,389,661 cases of serious fungal infection occurred in Vietnam in 2020. The most common condition was recurrent vaginal candidiasis (4047/100,000 women annually). Among people living with HIV, we estimated 451 cases of cryptococcal meningitis, 1030 of pneumocystis pneumonia, 166 of histoplasmosis and 1612 of talaromycosis annually. Candidaemia incidence was estimated at 12/100,000 population each year. Owing to its high burden of tuberculosis and respiratory diseases, Vietnam had high rates of severe infections caused by Aspergillus species. Incidence of invasive aspergillosis is 24/100,000 population, allergic bronchopulmonary aspergillosis 78/100,000 and severe asthma with fungal sensitisation 102/100,000. Five‐year period prevalence of chronic pulmonary aspergillosis is 120/100,000 population /5‐year period. Mucormycosis, fungal keratitis and tinea capitis were estimated at 192, 14,431 and 201 episodes each year, respectively. Conclusions The number of patients with mycoses in Vietnam is likely underestimated due to a lack of local data and limited diagnostic capacity, but at least 2.5% of the population might have some form of serious fungal disease.

“…At our center, post-pulmonary tuberculosis lung disease (PTBLD) is the most common predisposing lung disease for CPA [ 1 , 2 ]. CPA has a considerable global burden, with an estimated burden of over 300,000 cases annually in India alone [ 3 , 4 ]. CPA is a progressive disease with a 5-year mortality of 30–40% [ 5 , 6 ].…”
