Animal rabies in Mozambique: a retrospective study with focus on dog rabies and vaccination coverage.

Rabies, a highly preventable zoonotic disease, remains a major public health problem in Mozambique with approximately 50 human fatalities per annum due to dog-mediated rabies. This study analysed animal rabies cases and dog vaccination coverage, confirmed between 2001 and 2021, based on history, clinical signs, and/or diagnostic tests. During this period, 955 animal rabies cases were reported with the highest occurrence in Maputo ( = 283; 29.

Outcomes from a Zoonotic Disease Prioritization workshop using One Health approach in Mozambique, 2018 to 2023.

Introduction: Around 75% of (re)emerging infections are of zoonotic origins. The risk of zoonotic transmission in Mozambique is high because approximately 81% of the country's labor force is involved with agriculture, which represents a vulnerability for more frequent human-animal interaction and risk of spillover events. A One Health Zoonotic Disease Prioritization (OHZDP) workshop was conducted in Mozambique to facilitate coordination and collaboration within and across sectors to prevent, detect, and respond to zoonotic disease threats.

A Phylogeographic Analysis of Porcine Parvovirus 1 in Africa.

Porcine parvovirus 1 (PPV1) is recognized as a major cause of reproductive failure in pigs, leading to several clinical outcomes globally known as SMEDI. Despite being known since the late 1960s its circulation is still of relevance to swine producers. Additionally, the emergence of variants such as the virulent 27a strain, for which lower protection induced by vaccines has been demonstrated, is of increasing concern.

Detection and genetic diversity of Mopeia virus in Mastomys natalensis from different habitats in the Limpopo National Park, Mozambique.

Mammarenaviruses have been a growing concern for public health in Africa since the 1970s when Lassa virus cases in humans were first described in west Africa. In southern Africa, a single outbreak of Lujo virus was reported to date in South Africa in 2008 with a case fatality rate of 80%. The natural reservoir of Lassa virus is Mastomys natalensis while for the Lujo virus the natural host has yet to be identified.

Porcine circovirus-2 in Africa: Identification of continent-specific clusters and evidence of independent viral introductions from Europe, North America and Asia.

Porcine circovirus-2 (PCV-2) is associated with several disease syndromes in domestic pigs that have a significant impact on global pig production and health. Currently, little is known about the status of PCV-2 in Africa. In this study, a total of 408 archived DNA samples collected from pigs in Burkina Faso, Cameroon, Cape Verde, Ethiopia, the Democratic Republic of the Congo, Mozambique, Nigeria, Senegal, Tanzania and Zambia between 2000 and 2018 were screened by PCR for the presence of PCV-2.

Identification of porcine circovirus-3 in Mozambique.

Porcine circovirus 3 (PCV-3) has been associated with an assortment of clinical conditions in pigs and has been reported in many countries worldwide. In Africa there is no data on the presence of PCV-3. In this study, DNA samples collected from 91 pigs between 2011 and 2019 in nine of the ten provinces of Mozambique in the context of African swine fever (ASF) monitoring were further screened for the presence of PCV-3.

External quality assessment of Rift Valley fever diagnosis in countries at risk of the disease: African, Indian Ocean and Middle-East regions.

Rift Valley fever virus (RVFV), an arbovirus belonging to the Phlebovirus genus of the Phenuiviridae family, causes the zoonotic and mosquito-borne RVF. The virus, which primarily affects livestock (ruminants and camels) and humans, is at the origin of recent major outbreaks across the African continent (Mauritania, Libya, Sudan), and in the South-Western Indian Ocean (SWIO) islands (Mayotte). In order to be better prepared for upcoming outbreaks, to predict its introduction in RVFV unscathed countries, and to run efficient surveillance programmes, the priority is harmonising and improving the diagnostic capacity of endemic countries and/or countries considered to be at risk of RVF.

Prevalence and genome characterization of porcine rotavirus A in southern Mozambique.

Rotavirus A (RVA) is an important pathogen causing gastroenteritis in many species, including humans and pigs. The objective of this study was to determine the prevalence of RVA in pigs from smallholdings and commercial farms in southern Mozambique and characterize the complete genomes of selected strains. RVA was detected at a rate of 11.

Peste des Petits Ruminants Virus Surveillance in Domestic Small Ruminants, Mozambique (2015 and 2017).

Peste des Petits Ruminants (PPR), a transboundary animal disease affecting mainly goats and sheep is caused by a morbillivirus and threatens food security and livelihoods as morbidity and mortality rates can reach 90%. There are no records of PPR in Mozambique, but the disease situation in Tanzania and the ability of PPR virus to rapidly spread across countries constitute a high risk for about 4.7 million goats and sheep in Mozambique.

Molecular characterization of avipoxviruses circulating in Mozambique, 2016-2018.

Samples from 45 chickens, two turkeys, one peacock and one quail with symptoms of fowlpox were collected in Mozambique between November 2016 and January 2018. Phylogenetic analysis revealed that the samples contained avipoxviruses belonging to both clade A1 and clade A2. In addition, all of the Clade A1 viruses were positive by PCR for the integration of reticuloendotheliosis virus, while the clade A2 avipoxvirus samples were negative.

Detection and phylogenetic characterization of porcine circovirus 2 from pigs in Mozambique.

Porcine circovirus-associated diseases (PCVADs), caused by porcine circovirus 2 (PCV-2), have a significant economic impact on the swine industry worldwide. In Africa, there is little information, to date, regarding the occurrence of PCV-2, and it has not been reported in Mozambique's swine population. We randomly collected mesenteric lymph nodes ( n = 111) from slaughtered pigs from 9 districts in southern Mozambique.

High seroprevalence of Rift Valley fever phlebovirus in domestic ruminants and African Buffaloes in Mozambique shows need for intensified surveillance.

: Rift Valley fever (RVF) is an arthropod-borne disease that affects both animals and humans. RVF phlebovirus (RVFPV) is widespread in Africa and Arabian Peninsula. In Mozambique, outbreaks were reported in South; seroprevalence studies performed in livestock and water buffaloes were limited to central and south regions.

Identification of Clade E Avipoxvirus, Mozambique, 2016.

Analysis of scab samples collected from poultry during outbreaks of fowlpox in Mozambique in 2016 revealed the presence of clade E avipoxviruses. Infected poultry were from flocks that had been vaccinated against fowlpox virus. These findings require urgent reevaluation of the vaccine formula and control strategies in this country.

Phylogenetic analysis of Newcastle disease viruses isolated from commercial poultry in Mozambique (2011-2016).

The complete sequence of the fusion (F) protein gene from 11 Newcastle disease viruses (NDVs) isolated from commercial poultry in Mozambique between 2011 and 2016 has been generated. The F gene cleavage site motif for all 11 isolates was (112)RRRKRF(117) indicating that the viruses are virulent. A phylogenetic analysis using the full F gene sequence revealed that the viruses clustered within genotype VIIh and showed a higher similarity to NDVs from South Africa, China and Southeast Asia than to viruses previously described in Mozambique in 1994, 1995 and 2005.

An investigation into an outbreak of Rift Valley fever on a cattle farm in Bela-Bela, South Africa, in 2008.

In 2008, a suspected outbreak of Rift Valley fever (RVF) was reported on a farm in the Bela-Bela area, Limpopo Province, South Africa. Seven calves died on the affected dairy farm, where no RVF vaccination programme was practised. No apparent clinical disease was reported in the other 300 cattle (33 calves included) or 200 sheep on the farm.

Geographic distribution and prevalence of schistosomiasis and soil-transmitted helminths among schoolchildren in Mozambique.

Schistosomiasis and soil-transmitted helminths (STHs) are most prevalent in developing countries. In Mozambique, the first and only national survey of the distribution and prevalence of schistosomiasis and STHs was conducted in 1952 and 1957. Only occasional surveys in restricted areas have been conducted since the 1950s.
