The Effect of Short Treatment with Nigella Sativa on Symptoms, the Cluster of Differentiation (CD) Profile, and Inflammatory Markers in Mild COVID-19 Patients: A Randomized, Double-Blind Controlled Trial.

Unlabelled: The current study investigated the impact of different doses of seeds on the symptoms, the cluster of differentiation profile group, and inflammatory markers of mild COVID-19 cases.

Methods: The study was a double-blind placebo-controlled clinical trial. Patients with mild and asymptomatic SARS-CoV-2 infection patients were randomly subdivided into seven subgroups: Group (GP) 1: received charcoal capsules as a control group, and GP 2: received three capsules of whole seeds daily, two capsules in the morning and one in the evening; GP 3: received three capsules of whole seeds every 12 h, GP 4: received five capsules in the morning and four capsules of whole seeds in the evening, GP 5: received one capsule of powder every 12 h; GP 6: received two capsules of powder every 12 h; GP 7: received three capsules of powder every 12 h; all treatment course was for ten days.

Microbial surveillance of Hajj tents: Bioaerosol sampling coupled with real-time multiplex PCR.

Background: Respiratory tract infections are common among pilgrims attending annual Hajj in Mecca, Saudi Arabia. Pilgrims typically spend most of the Hajj period inside ventilated tents, where microorganisms may be transmitted through bioaerosols and droplets.

Objective: To perform microorganism surveillance inside Hajj tents and assess the similarities between microorganisms isolated from tent bioaerosol samples and nasopharyngeal swabs (NP) of tent occupants.
