Abstract

Despite the wide use of vaccination, measles outbreaks still occur. This study assessed cases notified during a measles outbreak in northern Sudan in 2011 and the response of the health authorities to contain the outbreak. The records of all measles cases reported to the River Nile State health ministry in 2011 from the Abu Hamad locality, a gold-mining area, were reviewed together with the actions of the health authorities at the time of the outbreak. Seventeen gold-mining clusters were included. Data on demographic, clinical, geographic and chronological characteristics of the cases were extracted. The outbreak occurred from 27 January to 3 May 2011 with the peak in epidemiological week 9. A total of 445 measles cases were recorded, giving an incidence of 27.1 per 10 000 of the mining and resident population. Most cases (87.4%) were aged between 15 and 34 years. High fever was the most common symptom (99.3% of the cases), followed by conjunctivitis (80.4%); haemorrhage was recorded in 29.4%. Most cases (84.9%) were unvaccinated. Six deaths occurred (case fatality: 1.3%); two from cerebral coma and four from haemorrhagic shock. Severity of disease was significantly associated with place of origin of the cases (P = 0.003).

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
