Transmission of Neurosyphilis from Person to Person. Neurosyphilis is considered infectious but is not transmitted from person to person. Generally, a disease like this is caused by an infectious agent and not spread between people.
On May 29, 1953, Edmund Hillary and Tenzing Norgay completed the first confirmed ascent of Mount Everest, which stands 29,035 feet above sea level.
He perished not far from the summit on his 1924 expedition and his body was discovered in 1999. The challenge to climb the highest mountain has not waned since the peak was first conquered in 1953 by Sherpa Tenzing Norgay (Nepal) and Sir Edmund Hillary (New Zealand).
