First Record of Lutzomyia (Lutzomyia) longipalpis (Diptera: Psychodidae: Phlebotominae) on the Trinational Frontier (Brazil-Peru-Bolivia) of South-Western Amazonia.

In South America, the main sand fly species involved in the transmission of Leishmania infantum chagasi (Cunha & Chagas, 1937), etiological agent of the visceral leishmaniasis (VL), is Lutzomyia longipalpis (Lutz & Neiva, 1912). The species has been recorded in Colombia, Venezuela, Bolivia, Argentina, Paraguay, Uruguay, and Brazil, where it is recorded in 24 of the 27 Brazilian states, except Acre, Amazonas, and Santa Catarina. Collections were carried out for one year (April 2013 to March 2014) using modified CDC light traps in different environments in Assis Brasil municipality, state of Acr…

Critical aspects of yellow fever control in Brazil.

This paper presents epidemiological and control characteristics of yellow fever in Brazil, taking its wild and urban transmission cycles into consideration. No urban cases have been reported in Brazil since 1942, but urban yellow fever cases were reported in Paraguay in 2008, after more than 50 years without registered cases in the Americas. The two main objectives of yellow fever control programs in Brazil are to reduce the number of wild cases and to maintain zero incidence of urban cases. Although there is a consensus regarding control measures that should be applied in areas endemic for th…

Bothrops moojeni venom and its components - an overview.

Belonging to the Viperidae family, Bothrops moojeni are widely distributed in South America, tropical savanna ecoregion (Cerrado) of Argentina, Bolivia, Brazil, and Paraguay with medical importance in Brazil. Accidents caused by this species have a rapid local action with the development of tissue inflammation, causing erythema, pain, and increased clotting time, which can culminate in gangrene or tissue necrosis. Bothrops moojeni venom has a rich composition that remains underexplored, which is of utmost importance, both for elucidating the envenoming process and the vast library of new bioac…

Оценка риска международного распространения вируса желтой лихорадки: математический анализ вспышки в городе Асунсьон, 2008 год.

Вирус желтой лихорадки (YFV) — вирус, передаваемый противомоскитным путем и эндемический для тропической Африки и Южной Америки, может вызвать крупные вспышки заболеваний в городах. С легкостью международных поездок вспышки в городах могут привести к быстрому распространению и последующей передаче YFV в отдаленных районах. Мы разработали стохастическую мета-модель с разновидно выраженными сценариями трансмиссии, чтобы имитировать глобальное распространение YFV от одной городской вспышки ВИЧ-инфицированных авиаперевозчиков. В ходе моделирования вспышки в 2008 году в Асунсьоне, Парагвай, местные

Yellow fever virus (YFV), a mosquito-borne virus endemic to tropical Africa and South America, is capable of causing large urban outbreaks o … single urban outbreak by infected airline travelers. In simulations of a 2008 outbreak in Asunción, Paraguay, local outbreaks occurred in 12.8% of simulations and international spread in 2.0%. Using simple probabilistic models, we found that local incidence, travel rates, and basic transmission parameters are sufficient to assess the probability of introdu …

Comparison of Facial Proportions Between Eastern and Western Attractive Young Women.

The characteristics of what is considered a beautiful face differ between Eastern and Western countries.The authors of this study analyzed beauty pageant contestants using a three-dimensional (3D) photogrammetric analysis tool. All of the 3D photographs were taken between October and November 2016 in Seoul, Korea. The participants were 43 Miss Korea contestants (Group I) and 22 Miss Paraguay contestants (Group II).In absolute length, those in Group I had longer upper and middle faces. In the proportions of volume and length, Group I had larger upper and middle faces than Group II. Widths of th…

Country-Specific Data and Priorities for Pertussis in Latin America: Recent Findings From the Global Pertussis Initiative.

In 2023, the Global Pertussis Initiative met to assess the burden of and vaccination policies against pertussis in 10 Latin American countries. Although pertussis is a notifiable disease in the represented countries, poor disease awareness, underrecognition in older individuals, and limited laboratory capacity and supplies challenge the collection of robust epidemiological data. Infants in all 10 countries receive a 3-dose primary series followed by ≥2 boosters. Except for Paraguay and Venezuela, governments of the represented countries advise or mandate vaccination in pregnancy; however, cove…

[Migration and mental disorders in the Chiraguano civilization].

The ethnographic characteristics of the Chiriguanos allowed us to make up an experimental design to show the relationship between migration and mental pathology. The Chiriguanos are a South American ethnographic population characterized by a traditional migratory tendency. The Chiriguanos group is a resultant of the Tupi-Guaraní migrations. From the 15th century up to the 19th aboriginal guaraníes moved from the current area of Paraguay to the East zone of Bolivia; they conquered and mixed with the group that lived there and after that they resisted the European forces. The Chiriguanos history…

Systematic Review of Hansen Disease Attributed to Mycobacterium lepromatosis.

In 2008, bacilli from 2 Hansen disease (leprosy) cases were identified as a new species, Mycobacterium lepromatosis. We conducted a systematic review of studies investigating M. lepromatosis as a cause of HD. Twenty-one case reports described 27 patients with PCR-confirmed M. lepromatosis infection (6 dual M. leprae/M. lepromatosis): 10 case-patients in the United States (7 originally from Mexico), 6 in Mexico, 3 in the Dominican Republic, 2 each in Singapore and Myanmar, and 1 each in Indonesia, Paraguay, Cuba, and Canada. Twelve specimen surveys reported 1,098 PCR-positive findings from 1,42…

A facility birth can be the time to start family planning: postpartum intrauterine device experiences from six countries.

Initiation of family planning at the time of birth is opportune, since few women in low-resource settings who give birth in a facility return for further care. Postpartum family planning (PPFP) and postpartum intrauterine device (PPIUD) services were integrated into maternal care in six low- and middle-income countries, applying an insertion technique developed in Paraguay. Facilities with high delivery volume were selected to integrate PPFP/PPIUD services into routine care. Effective PPFP/PPIUD integration requires training and mentoring those providers assisting women at the time of birth. O…
