Clinical pleiomorphism in human leishmaniases, with special mention of asymptomatic infection
(Elsevier, 2011)
This review gives an update of current knowledge on the clinical pleiomorphism of Leishmania, with a special emphasis on the case of asymptomatic carriage. The first part describes the numerous unusual expressions of the ...
Insights into Plasmodium vivax Asymptomatic Malaria Infections and Direct Skin-Feeding Assays to Assess Onward Malaria Transmission in the Amazon
(American Journal of Tropical Medicine and Hygiene, 2022)
Understanding the reservoir and infectivity of Plasmodium gametocytes to vector mosquitoes is crucial to align strategies aimed at malaria transmission elimination. Yet, experimental information is scarce regarding the ...
Human rhinovirus infections in symptomatic and asymptomatic subjects
(Sociedade Brasileira de Microbiologia, 2012-12-01)
The role of rhinovirus asymptomatic infections in the transmission among close contacts subjects is unknown. We tested health care workers, a pair of one child and a family member and immunocompromised patients (n =191). ...
Asymptomatic SARS Coronavirus 2 infection: Invisible yet invincible
While successful containment measures of COVID-19 in China and many European countries
have led to flattened curves, case numbers are rising dramatically in other countries, with the
emergence of a second wave expected. ...
Relative contribution of low-density and asymptomatic infections to Plasmodium vivax transmission in the Amazon: pooled analysis of individual participant data from population-based cross-sectional surveys
(Elsevier, 2022)
Background: Low-density and asymptomatic Plasmodium vivax infections remain largely undetected and untreated and may contribute significantly to malaria transmission in the Amazon. Methods: We analysed individual participant ...
Asymptomatic carriers of Plasmodium spp. as infection source for malaria vector mosquitoes in the Brazilian Amazon
(2005-09-01)
We have described the existence of asymptomatic carriers of Plasmodium vivax and Plasmodium falciparum infections in native Amazon populations. Most of them had low parasitemias, detected only by polymerase chain reaction ...

Visualizing the invisible: The effect of asymptomatic transmission on the outbreak dynamics of COVID-19
(2020)
Understanding the outbreak dynamics of the COVID-19 pandemic has important implications for successful containment and mitigation strategies. Recent studies suggest that the population prevalence of SARS-CoV-2 antibodies, ...
The incidence of the novel coronavirus SARS-CoV-2 among asymptomatic patients: a systematic review
Background: the recent outbreak of the coronavirus disease 2019 (COVID‐ 19) has
quickly spread globally since its discovery in Wuhan, China, in December 2019. A comprehensive
strategy, including surveillance, diagnostics, ...
Transmission potential, skin inflammatory response, and parasitism of symptomatic and asymptomatic dogs with visceral leishmaniasis
(BIOMED CENTRAL LTD, 2008)
Background: Visceral leishmaniasis in Brazil is caused by the protozoan Leishmania (Leishmania) chagasi and it is transmitted by sandfly of the genus Lutzomyia. Dogs are an important domestic reservoir, and control of the ...
