African horse sickness (AHS) is a viral disease of equids, caused by a virus of the genus Orbivirus, family Reoviridae. The African horse sickness virus (AHSV) genome is made up of ten double-stranded RNA (dsRNA) segments that together code for seven structural and four nonstructural proteins. AHS is endemic in sub-Saharan countries. The efficacy and safety of inactivated AHS vaccines containing all nine serotypes, produced at the Central Veterinary Research Laboratory (CVRL) in Dubai, United Arab Emirates have been proven in the past. All nine AHSV serotypes were isolated from 102 samples collected in the last 20 years from horse fatalities in seven different area of Kenya, Africa. CVRL inactivated AHS vaccines are used in a few African countries defining the importance of this present study to compare the genome sequences of the nine AHSV serotypes isolated from horse fatalities in Kenya and nine AHSV serotypes isolated in South Africa. The hypothesized serotypes of the newly sequenced AHSV field strains from Kenya were likewise confirmed in this investigation, and they show substantial sequence homologies with recently isolated AHSV field strains.

Haemophilus influenzae serotype A is a rare cause of meningitis and invasive disease in pediatric patients. A six-month-old infant presented to the emergency room with fever, cough and nasal drip. On admission, the infant was alert and hemodynamically stable but progressively became more lethargic with bulging of the fontanelle.

Dengue fever is a vector-borne, acute, febrile, and self-limiting systemic viral infection that affects tropical and subtropical regions, including Pakistan. Karachi has a significant burden of Aedes aegypti and Aedes albopictus due to suitable breeding sites, weather, and rapid and unplanned urbanization of squatter areas. The country has limited surveillance studies on circulating serotypes of the dengue virus and the patient's clinical features evolving over temporal changes.
