By Dr. Stephen A. Berger   Cynomolgus monkey, a known reservoir of the Monkeypox virus   WHAT IS MONKEYPOX? Monkeypox, as the name implies, is a disease of monkeys (unlike chickenpox – which has no relation to chickens). Although the condition is reported in a group of eleven African countries, the virus was first discovered in a laboratory in Denmark in 1958, when it was first isolated from cynomolgus monkeys. The signs and symptoms are similar to those of smallpox. Following a three-day prodrome of fever, headache, myalgia, and back pain, patients develop a papular rash in the face, extremities, and genit...

ar H Abstract The ability to sequence genomes from ancient biological material has provided a rich source of information for evolutionary biology and engaged considerable public interest. Although most studies of ancient genomes have focused on vertebrates, particularly archaic humans, newer technologies allow the capture of microbial pathogens and microbiomes from ancient and historical human and non-human remains. This coming of age has been made possible by techniques that allow the preferential capture and amplification of discrete genomes from a background of predominantly host and environmental DNA. There ar...

Purpose of review This review provides a historic perspective of the impact that major pandemics have had on human and their relationship with ophthalmology. The novel coronavirus epidemic is also analyzed, highlighting the relevance of the eye as a possible source of transmission, infection, and prognosis for the disease. Results Smallpox is suspected to be present for more than 12 000 years. However, trachoma seems to be the first recorded ophthalmological infectious disease. The deadliest pandemics include the bubonic plague, smallpox, and Spanish flu. The CoVID-19 epidemic is still developing and measures need t...

Cells express multiple molecules aimed at detecting incoming virus and infection. Recognition of virus infection leads to the production of cytokines, chemokines and restriction factors that limit virus replication and activate an adaptive immune response offering long-term protection. Recognition of cytosolic DNA has become a central immune sensing mechanism involved in infection, autoinflammation, and cancer immunotherapy. Vaccinia virus (VACV) is the prototypic member of the family Poxviridae and the vaccine used to eradicate smallpox. VACV harbors enormous potential as a vaccine vector and several attenuated strains ar...

Dog vaccination programs are the most effective way to prevent Rabies   Rabies is endemic to over 150 countries, and according to the World Health Organization, 99% of all transmissions to humans are from dogs, potentially bringing into question the animal’s status as the ‘man’s best friend’.  In Europe, southern Africa, and parts of North America, most cases are acquired from wild carnivores; mongooses, and vampire bats in Latin America and the Caribbean. In more recent years, humans have acquired rabies from inhalation of aerosols in bat caves, ingestion of dogs and cats for food, ticks...

Abstract My career as an accidental nutritionist began with my immersion in cholera control, a cyclone disaster, a smallpox epidemic, and formal training in ophthalmology and epidemiology. Interest in blindness prevention inexplicably led me to (re)pioneer the effects, treatment, and prevention of vitamin A deficiency, while faced with intense criticism by many leading scientists in the nutrition community. The resulting efforts by the World Health Organization and UNICEF in support of programs for the global control of vitamin A deficiency still face vocal opposition by some senior scientists, despite having been...

(American Chemical Society) Vaccines have curtailed the spread of several infectious diseases, such as smallpox, polio and measles. However, vaccines against some diseases, including HIV-1, influenza and malaria, don't work very well, and one reason could be the timing of antigen and adjuvant presentation to the immune system. Now, researchers reporting inACS Central Science developed an injectable hydrogel that allows sustained release of vaccine components, increasing the potency, quality and duration of immune responses in mice.
