Cholera in 1994. Part I

Relevé épidémiologique Hebdomadaire

Abstract

In 1994, Vibrio cholerae O1 biotype El Tor, the agent responsible for the seventh cholera pandemic which began in 1961, continued to spread in all regions of the world (Map 1). In all, 384,403 cholera cases were officially reported to WHO in 1994 (a 2% increase over 1993), reversing the downward trend which started in 1992. A total of 10,692 deaths were reported in 1994, increasing the reported global case-fatality ratio (CFR) to 2.8% from 1.8% in 1993. Cholera cases were notified from 94 countries/areas, the highest number ever reporting in one year. (Table 1 and Fig. 1). The year was marked by the dramatic cholera outbreak that devastated the Rwandan refugee camps in Goma, Zaire in July. Major outbreaks also affected Afghanistan, Brazil, Guinea, Guinea-Bissau and Somalia. Africa reported a rise in the number of cholera cases, and was the continent accounting for the largest proportion of all reported cases. The incidence of cholera cases in the Americas continued to fall and reported CFR was the lowest recorded since the disease reached Latin America in 1991. Asia reported a 17% increase in cholera cases compared with 1993. Europe, which usually reports only imported cases, registered a significant increase in the number of i...Continue Reading

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.
