COVID-19 unfolding filariasis: The first case of SARS-CoV-2 and Wuchereria bancrofti coinfection.

With the evolution of the Coronavirus Disease 2019 (COVID-19) pandemic, the number of patients brought to medical attention has increased. This has led to the unmasking of many coexisting occult infections and comorbidities such as tuberculosis, dengue, human immunodeficiency viral infection, diabetes, and hypertension. We report the first case of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, unveiling the diagnosis of asymptomatic filariasis. A 37-year-old gentleman presented with shortness of breath, fever, and cough. He was found to have COVID-19 pneumonia. During his stay, microfilaria of Wuchereria bancrofti was detected incidentally on a blood smear exam. Consequently, the patient received appropriate treatment for both conditions. In order not to miss relevant concomitant diagnoses, it is prudent to keep a broad differential diagnosis when faced with SARS-CoV-2-infected patients; this is especially true when atypical symptoms are present or in areas endemic with other infections.

Case Report: Disseminated Strongyloidiasis in a Patient with COVID-19.

The SARS-CoV-2 virus has emerged and rapidly evolved into a current global pandemic. Although bacterial and fungal coinfections have been associated with COVID-19, little is known about parasitic infection. We report a case of a COVID-19 patient who developed disseminated strongyloidiasis following treatment with high-dose corticosteroids and tocilizumab. Screening for Strongyloides infection should be pursued in individuals with COVID-19 who originate from endemic regions before initiating immunosuppressive therapy.

The potential public health consequences of COVID-19 on malaria in Africa.

The burden of malaria is heavily concentrated in sub-Saharan Africa (SSA) where cases and deaths associated with COVID-19 are rising1. In response, countries are implementing societal measures aimed at curtailing transmission of SARS-CoV-22,3. Despite these measures, the COVID-19 epidemic could still result in millions of deaths as local health facilities become overwhelmed4. Advances in malaria control this century have been largely due to distribution of long-lasting insecticidal nets (LLINs)5, with many SSA countries having planned campaigns for 2020. In the present study, we use COVID-19 and malaria transmission models to estimate the impact of disruption of malaria prevention activities and other core health services under four different COVID-19 epidemic scenarios. If activities are halted, the malaria burden in 2020 could be more than double that of 2019. In Nigeria alone, reducing case management for 6 months and delaying LLIN campaigns could result in 81,000 (44,000-119,000) additional deaths. Mitigating these negative impacts is achievable, and LLIN distributions in particular should be prioritized alongside access to antimalarial treatments to prevent substantial malaria epidemics.

Etiology and epidemiology of viral pneumonia among hospitalized children in rural Mozambique: a malaria endemic area with high prevalence of human immunodeficiency virus.

BACKGROUND: The role of viruses in pediatric pneumonia remains poorly studied in sub-Saharan Africa, where pneumonia-associated mortality is high. METHODS: During a 1-year hospital-based surveillance, a nasopharyngeal aspirate (NPA) was collected from children aged <5 years admitted to hospital in rural Mozambique with clinically severe pneumonia. Identification of 12 respiratory viruses was performed by polymerase chain reactions (PCR). Study children were also tested for invasive bacterial infection (IBI), Plasmodium falciparum parasitemia, and HIV. RESULTS: Almost half (394/807) of the children hospitalized with clinically severe pneumonia had at least one respiratory virus detected. A total of 475 viruses were detected among these 394 children, the most prevalent ones were rhinovirus (41%), adenovirus (21%), and respiratory syncytial virus (11%). Eleven percent of viral infected children had concomitant IBI, 15% had malaria parasites, and 25% had HIV coinfection. Viral infection was 5.5 to 16 times more prevalent among HIV-infected children and incidence rate ratios varied according to virus. Inhospital mortality of viral cases was 9%, being highest among cases with IBI coinfection (odds ratio = 7) or HIV infection (odds ratio = 7). CONCLUSIONS: Study results highlight the high prevalence of respiratory viruses among hospitalized pneumonia cases in Mozambique. HIV infection is an important contributor to the high burden of disease and associated mortality of viral pneumonia. IBI also contributes to a worse prognosis of viral cases. Strategies to prevent mother-to-child transmission of HIV as well as introduction of Hib and pneumococcal vaccines could have a substantial impact on reduction of viral pneumonia and associated mortality among children in rural Africa.
