Can Smallpox Be Weaponised?

So, an R0 of 7, for example, means that, on average, one sick person will infect seven other individuals. The reproduction rate of an infectious pathogen can be affected by various factors such as preventative public health measures and the presence of immunity, acquired either naturally or through vaccination. As immunity to a particular pathogen builds up in a given population, a measure known as Re, or effective reproduction number, becomes more appropriate to use when estimating the number of people who can be infected by an individual at any specific time.

In addition, the agency says on one page of the document that the variant is as transmissible as chickenpox. On this page, a graph is featured that was originally published by The New York Times in showing the transmissibility of various pathogens, including the ancestral SARS-CoV-2 virus. The CDC has updated the graph to include information on the new Delta variant. According to the graph, the variant appears to be as transmissible as chickenpox, which is shown to have an R0 value of around 8. But other common estimates for the R0 value of chickenpox indicate a range of , which would mean that infection caused by the varicella-zoster virus is slightly more transmissible than the Delta variant of SARS-CoV Nevertheless, the Delta variant appears to be less transmissible than measles, which is one of the most infectious pathogens that we know about.

The R0 of measles is often cited to be , meaning that on average, one infected person would transmit the disease to others in a totally susceptible population. In fact, measles is so contagious that up to 90 percent of people close to an infected person who are not immune will also become infected, according to the CDC. The internal CDC document suggests that fully vaccinated people infected with Delta may be capable of spreading the variant at the same rate as unvaccinated people.

The document also says that the variant has been associated with a slightly increased risk of more severe illness. There are four types of variola major smallpox: ordinary the most frequent ; modified mild and occurring in previously vaccinated persons ; flat; and hemorrhagic. However, flat and hemorrhagic smallpox, which are uncommon types of smallpox, are usually fatal. Hemorrhagic smallpox has a much shorter incubation period and is likely not to be initially recognized as smallpox when presenting to medical care. Smallpox vaccination also does not provide much protection, if any, against hemorrhagic smallpox. Variola virus is the etiological agent of smallpox. During the smallpox era, the only known reservoir for the virus was humans; no known animal or insect reservoirs or vectors existed.

The most frequent mode of transmission was person-to-person, spread through direct deposit of infective droplets onto the nasal, oral, or pharyngeal mucosal membranes, or the alveoli of the lungs from close, face-to-face contact with an infectious person. Indirect spread i. Symptoms of smallpox begin days range: after exposure, starting with a day prodrome of high fever, malaise, and prostration with severe headache and backache. This preeruptive stage is followed by the appearance of a maculopapular rash i.

The rash appears first on the oral mucosa, face, and forearms, then spreads to the trunk and legs. Lesions might erupt on the palms and soles as well. Smallpox skin lesions are deeply embedded in the dermis and feel like firm round objects embedded in the skin.
