The report by NTI also stated North Korea was capable of indigenously producing other agents of biological warfare including Variola major
(smallpox), Francisella tularensis (rabbit fever), and Bunyaviridae Hantavirus (Korean hemorrhagic fever).
Caused by the variola major
virus, smallpox inflicted great pain on victims, beginning with fever, nausea and other flu-like symptoms before leading to lesions on the face and body.
What's more, she had contracted the deadliest strain, Variola major
On the other hand, Langmuir, Usher and the CDC were surely right to emphasize the great difficulty eradication would actually entail, especially in East Bengal, and it's no an accident that the very last cases on earth of Variola major
were stamped out in Bangladesh--the former East Pakistan--late in 1975.
His mother, Eleanor McMillan, was a graduate of Chatham Hospital School of Nursing and worked on the smallpox wards at Henry Ford Hospital during North America's last outbreak of variola major
in Detroit and Windsor in 1924; his uncle, William McMillan, a physician, would become the ranking Liberal Member of Parliament in the 1960s.
Category A biological agents include: Variola major
(smallpox), Bacillus anthracis (anthrax), Yersinia pestis (plague), Clostridium botulinum (botulism), Francisella tularensis (tularemia) and filoviruses and arena viruses (such as Ebola and Lassa virus which result in viral hemorrhagic fever) (CDC 200511).
caused a serious disease that killed between 10 percent and 30 percent of its victims, whereas variola minor gave rise to a much milder illness called alastrim, with a case mortality rate of less than 1 percent.
In 1975 the last case of smallpox caused by wild variola major
was in a 3-year-old Bangladeshi girl (last case in Asia) and the last case of smallpox caused by wild variola minor was in a 23-year-old Somalian in December 1977.
Parker was diagnosed as having contracted variola major
, the most lethal type of the disease.
Analysis of the complete genome of smallpox variola major
virus strain Bangladesh-1975.
Overall, the average death rate of all types of variola major
is about 30%.
The CDC also has identified an "A" list of biological agents of highest concern, which includes (a) variola major
(smallpox), (b) Bacillus anthracis (anthrax), (c) Yersinia pestis (plague), (d) Francisella tularensis (tularemia), (e) botulinum toxin (botulism), and (f) filoviruses and arenaviruses (viral hemorrhagic fevers).
