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.

“…Malaria and lymphatic filariasis (LF) cited as one of the main mosquito-borne human diseases, exhibit a high level of morbidity and mortality in Sub-Saharan Africa. These are parasitic diseases, which Wuchereria bancrofti is responsible for the majority cases of LF and most malaria cases are caused by Plasmodium falciparum [ 2 ]. The parasites of both diseases are in majority transmitted by mosquitoes of the genus Anopheles in West Africa [ 3 , 4 ].…”

Background Entomological surveillance of lymphatic filariasis and malaria infections play an important role in the decision-making of national programs to control, or eliminate these both diseases. In areas where both diseases prevalence is low, a large number of mosquitoes need to be sampled to determine vectors infection rate. To do this, efficient mosquito collection methods must be used. This study is part in this framework, to assess appropriate mosquito collection methods for lymphatic filariasis xenomonitoring in a coexistence context with malaria in Burkina Faso. Methodology/Principal findings Mosquito collections were performed between August and September 2018 in four villages (Koulpissi, Seiga, and Péribgan, Saptan), distributed in East and South-West health regions of Burkina Faso. Different collection methods were used: Human Landing Catches (HLC) executed indoor and outdoor, Window Exit-Trap, Double Net Trap (DNT) and Pyrethrum Spray Catches (PSC). Molecular analyses were performed to identify Anopheles gambiae s.l. sibling species and to detect Wuchereria bancrofti and Plasmodium falciparum infection in Anopheles mosquitoes. A total of 3 322 mosquitoes were collected among this, Anopheles gambiae s.l. was the vector caught in largest proportion (63.82%). An. gambiae s.l. sibling species molecular characterization showed that An. gambiae was the dominant specie in all villages. The Human Landing Catches (indoor and outdoor) collected the highest proportion of mosquitoes (between 61.5% and 82.79%). For the sampling vectors infected to W. bancrofti or P. falciparum, PSC, HLC and Window Exit-Trap were found the most effective collection methods. Conclusions/Significance This study revealed that HLC indoor and outdoor remained the most effective collection method. Likewise, the results showed the probability to use Window Exit-Trap and PSC collection methods to sample Anopheles infected.

“…Human Landing Catches (HLC), Window Exit-Trap, Double Net Trap (DNT) and Pyrethrum Spray Catches (PSC) were evaluated. The results showed that HLC remained the most effective collection method by collecting the highest number of Anopheles (2,388; 71.88% of total). Across the study, mosquito infection rate for Wuchereria bancrofti and Plasmodium falciparum were 0.004 and 0.13 respectively.…”

BackgroundEntomological surveillance of lymphatic filariasis (LF) and malaria infections play an important role in the decision-making of national programs, to control or eliminate these both diseases. In order to corroborate infections in the human population, sampling large numbers of mosquitoes is necessary. To overcome this challenge, this study was design to assess the efficiency of four mosquito collection methods for monitoring LF and malaria infections in mosquito population.Methodology/Principle FindingsMosquito collections were performed between August and September 2018 in four villages (Koulpissy, Seiga, and Péribgan, Saptan), distributed in East and South-West health regions of Burkina Faso. Different collection methods were used: Human Landing Catches (HLC) executed indoor and outdoor, Window Exit-Trap, Double Net Trap (DNT) and Pyrethrum Spray Catches (PSC). Molecular analyses were performed to identify Anopheles gambiae s.l. sibling species and to detect Wuchereria bancrofti and Plasmodium falciparum infection in mosquitoes. A total of 3,322 mosquitoes were collected among this, Anopheles gambiaes.l. was the vector caught in largest proportion (63.82%). An. gambiae s.l. sibling species molecular characterization showed that Anopheles gambiae was the dominant specie in all health regions. The Human Landing Catches (indoor and outdoor) collected the highest proportion of mosquitoes (between 61.5%and 82.79%). For sampling vectors infected to W. bancrofti and P. falciparum, PSC, HLC and Window Exit-Trap were been find as the most effective collection methods.Conclusions/SignificanceThis study revealed that HLC indoor and outdoor remained the most effective collection methods. Likewise, the results showed the probability to use Window Exit-Trap and PSC collection methods to sample Anopheles infected and can be useful for xenomonitoring for both LF and malaria.Author summaryIn Burkina Faso the monitoring and evaluation scheme to assess the impact of LF and malaria interventions is only focusing on parasitological tests. While nowadays, the most simple and direct measure of vector borne diseases is xenomonitoring. Thus, in order to confirm both diseases infection rate in the human population, sampling large numbers of mosquitoes is necessary. This study was undertaken in this context to assess the efficiency of four mosquito collection methods for xenomonitoring LF and malaria. Mosquito collections were performed between August and September 2018 in four villages, distributed in East and South-West health regions of Burkina Faso. Human Landing Catches (HLC), Window Exit-Trap, Double Net Trap (DNT) and Pyrethrum Spray Catches (PSC) were evaluated. The results showed that HLC remained the most effective collection method by collecting the highest number of Anopheles (2,388; 71.88% of total). Across the study, mosquito infection rate for Wuchereria bancrofti and Plasmodium falciparum were 0.004 and 0.13 respectively. To collect vectors infected it was found that Window Exit-Trap and PSC were efficiencies. In conclusion, HLC has shown to be appropriate for collect large number of mosquitoes. Likewise, Window Exit-Trap and PSC can be useful for xenomonitoring for both LF and malaria.
