INTRODUCTION

Peste des Petits Ruminants virus (PPRV) is a highly contagious transboundary pathogen of small ruminants, with goats being more severely affected than sheep (Kabir et al., 2019, 2020). PPRV is an enveloped, single-stranded, negative-sense RNA virus belonging to the genus Morbillivirus in the family Paramyxoviridae (Fentahun et al., 2012). Globally, four distinct genetic lineages (I–IV) have been identified, with lineage IV predominating in Asia, including Pakistan (Abubakar et al., 2017; Ullah et al., 2022). Although sheep and goats are the primary hosts, spillover infections have occasionally been reported in cattle, buffalo, and camels (Abraham et al., 2005).

Commonly referred to as goat plague, kata, or pseudo-rinderpest, PPR is characterized by high morbidity and mortality, with outbreaks sometimes affecting up to 90% of animals in a herd and causing 30–70% mortality (Abdollahpour et al., 2006). Clinically, PPR manifests as peracute, acute, or subacute forms, presenting with high fever, ocular and nasal discharges, necrotic stomatitis, pneumonia, diarrhea, and significant mortality among young animals (Kabir et al., 2019; Radostitis et al., 2007; Abubakar and Irfan, 2014; Zakian et al., 2016).

Transmission occurs primarily via direct contact with infected secretions and indirectly through contaminated feed, water, and fomites (Abubakar et al., 2015; Nour, 2020). First described in Côte d’Ivoire in 1942, PPR has now spread across Africa, the Middle East, and Asia and is endemic in more than 70 countries worldwide. In Pakistan, the disease was first reported in 1991 and confirmed in 1994 (Shaila et al., 1996; Zahur et al., 2006; Singh et al., 2009; Mdetele et al., 2021). Despite its endemic status, limited epidemiological data are available from Kasur district, Punjab, underscoring the need for region-specific investigations.

MATERIALS AND METHODS

Study area and duration

The study was conducted at the Veterinary Teaching Hospital, University of Veterinary and Animal Sciences (UVAS), Ravi Campus Pattoki, District Kasur, Punjab, Pakistan. Kasur is located about 50 km South of Lahore and shares borders with India to the east and southeast, Okara to the southwest, Sheikhupura to the northwest, and Lahore to the north (Figure 1). The district comprises four tehsils: Kasur, Chunian, Pattoki, and Kot Radha Kishan. The study period extended over six weeks, from 10 August to 25 September 2024.

Study population and sampling

A total of 165 goats were randomly selected from routine cases presented to the teaching hospital, regardless of breed, sex, age, or health status. Owner-provided information regarding animal history and management practices was recorded using a structured questionnaire and cross-verified with hospital records to ensure consistency.

Clinical examination

Each goat underwent a systematic clinical examination to assess signs of Peste des Petits Ruminants(PPR) Table 1.

Clinical diagnosis

Diagnosis of PPR was based on history, owner-reported complaints, and observed clinical signs, including inspection, auscultation, and respiratory assessment. Laboratory confirmation was not performed; therefore, findings are limited to clinically suspected cases.

 

RESULTS

General prevalence

In this study total 165 goats was examined, 49 goats were clinically diagnosed positive for PPR infection through the clinical signs like fever (105-107°F), severe diarrhea, oral lesions, respiratory distress, oculo-nasal discharge, dull and dehydration as shown in Figure 2, and other 116 goats were observed negative for PPR infection, so the general prevalence of PPR in District Kasur is 29.70% (49/165) (Figure 3).

Breed-wise prevalence

Out of 165 goats examined, prevalence of Peste des Petits Ruminants (PPR) varied significantly across breeds (χ² = 52.47, p < 0.001). The highest prevalence was observed in Teddi (86.7%) and Tappri (75.0%) breeds, followed by Cross (43.8%) and Gulabi (60.0%). In contrast, Beetal (10.7%), Pateri (16.7%), and Makhi Cheeni (18.2%) showed relatively lower prevalence rates (Table 2).

Age-wise prevalence

PPR prevalence was significantly associated with age (χ²= 11.48, p= 0.003). The highest prevalence occurred in goats aged 7–18 months (39.8%), followed by <6 months (23.3%), while adults >18 months showed the lowest prevalence (11.9%) (Table 3).

Sex-wise prevalence

No statistically significant difference in PPR prevalence was observed between male (33.3%) and female (25.9%) goats (χ² = 0.76, p = 0.38) (Table 4).

DISCUSSION

The breed-wise prevalence in this study (χ² = 52.47, p < 0.001) demonstrated significant variation among goat breeds, with Teddi (86.7 %) and Tappri (75.0 %) showing exceptionally high prevalence, while Beetal (10.7 %) and Pateri (16.7 %) showed lower values. Such disparity may reflect breed-specific susceptibility, management, or husbandry practices. Similar differential prevalence among breeds has been reported elsewhere, indicating that local breed adaptation, immune competence, and biosecurity measures may influence infection rates (Abubakar et al. 2017). Our overall prevalence (29.7 %) is lower than some national pooled estimates in Pakistan, where a meta-analysis estimated pooled prevalence at ~51 % over 2004–2023 (Zafar et al., 2024) but aligns with observations that PPR prevalence can vary widely by region and sampling method (Abubakar et al., 2015).

Age-wise, the highest prevalence was in goats aged 7–18 months (39.8 %), followed by <6 months (23.3 %) and >18 months (11.9 %). This pattern is consistent with many studies showing that younger and growing animals are more vulnerable due to declining maternal antibodies and increased exposure as they join grazing herds (Kabir et al., 2020). In Pakistan, prior studies also noted that PPR infection is more frequent in animals under two years of age (Jalees et al., 2013).

Regarding sex, although male goats had a slightly higher prevalence (33.3 %) than females (25.9 %), the difference was not statistically significant (χ² = 0.76, p = 0.38). This lack of sex-based disparity is in agreement with findings from similar epidemiological surveys, which often show no clear gender predisposition for PPR (Wendimu et al., 2024).

The observed breed and age associations highlight potential targets for control. The particularly high prevalence in indigenous breeds like Teddi and Tappri suggests that vaccination and management strategies need to be breed-specific, addressing local husbandry practices and genetic vulnerability. Young goats (7-18 months) appear to be a critical risk group and may benefit most from timely immunization and enhanced monitoring.

Other factors likely also contribute to variability in prevalence: animal movement, agro-climatic conditions, vaccination coverage, and biosecurity practices. The national serosurveillance across Pakistan found that differences in sero-positivity among provinces were attributed partly to animal movement and ecological differences (Abubakar et al., 2017).

Limitations of this study include reliance on clinical diagnosis without laboratory confirmation, which may under- or overestimate true prevalence. Also, sample sizes for some breeds (e.g. Gulabi, Pateri) were small, leading to wide confidence intervals. Future studies should incorporate serological or molecular confirmation and consider multivariable risk modeling (e.g. logistic regression) to adjust for confounders.

In summary, this study indicates that PPR remains endemic in goats of Kasur district, with clear breed and age differentials in susceptibility. Effective control will require targeted vaccination, improved surveillance, and strengthening of biosecurity practices tailored to high-risk breeds and age groups.

NOVELTY STATEMENT

This study presents the first field-based clinical assessment of PPR in goats from Kasur district, revealing significant breed- and age-related differences in disease prevalence. Teddi and Tappri goats, along with young animals (7–18 months), were most affected. These findings provide novel insights to guide targeted vaccination and control strategies in endemic areas of Punjab.
