greed and excitement caused by a gold rush.
: the contagious excitement of a gold rush.
The California Gold Rush was sparked by the discovery of gold nuggets in the Sacramento Valley in early 1848 and was arguably one of the most significant events to shape American history during the first half of the 19th century.
By the spring of 1848, people poured out of San Francisco hoping to strike it rich. It is said that San Francisco emptied after businessman Sam Brannan walked down the city's Montgomery Street with a bottle containing gold flakes, grains, and dust, shouting: “Gold! Gold!

On 12 February 1851, Edward Hargraves found five grains of gold in mud washed from Lewis Ponds Creek. Gold was such a valuable and desired material that for a while, the whole country was caught up in 'gold fever'. Men left their jobs, homes and families to rush to the goldfields in New South Wales and Victoria.
Yellow fever is spread by the bite of infected Aedes aegypti mosquitoes. A mosquito becomes infected when it bites a person who has yellow fever in his or her blood. Direct spread of yellow fever from one person to another does not occur.
The California Gold Rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad.
One of the biggest gold rushes in history was started in New South Wales, Australia, in 1851. Hundreds of thousands of "diggers" from other parts of Australia, Great Britain, Poland, Germany, and even California sought their fortunes and redefined Australia's national identity.
Edward Hammond Hargraves is credited with finding the first payable goldfields at Ophir, near Bathurst, New South Wales, on 12 February 1851. News of gold spread quickly around the world and in 1852 alone, 370,000 immigrants arrived in Australia. By 1871, the national population had trebled to 1.7 million.
The only cure for gold fever was to get to California. This rush of folks to find gold was the largest gold rush ever in the United States. The people who came in 1849 were called “forty-niners.” So many people came that California became the thirty-first state on September 9, 1850.
In 1848 mineralogist William Tipple Smith found gold near Bathurst and the following year revealed the find to the NSW Colonial Secretary Edward Thomson. Research by one of Smith's relatives, Lynette Silver, established that Smith's find was the first discovery of payable gold.
Disease was rife upon the goldfields, where poor sanitation meant that refuse and excrement were liable to end up in the rivers that supplied drinking water for those on the diggings. Dysentery, typhus and other contagious diseases were all represented.
In the summer of 1899, news arrived that a fortune in gold dust had been uncovered on the beaches of Nome, Alaska. The reports immediately triggered a mass exodus from the Yukon. Dawson—which had once boasted a population of some 17,000—lost 8,000 residents. History's last great gold rush was effectively over.
In 1849 about 80,000 gold-seekers came to California, hoping to strike it rich. These gold-seeking migrants to California were called forty-niners.
California--1849
The 1848 discovery of gold at Sutter's Mill in California sparked the greatest gold rush of all time.
About 60% of Australia's gold resources occur in Western Australia, with the remainder in all other States and the Northern Territory.
In Australia this concentration of gold took place in the Earth hundreds of millions of years ago in the eastern states, and thousands of millions of years ago in Western Australia. As well as gold, the fluids can carry other dissolved minerals, such as quartz. This is why gold is often found with quartz.
The first person or civilization to discover gold is the Ancient Egyptians. They mined gold in Nubia around 2450 BC. An Egyptian alchemist named Zosimos was the first to find pure gold (24 centuries before Columbus reached the Americas).
The Australian gold rush was a large number of gold discoveries in Australia. Thousands of people came to Australia in the hope of finding a lot of gold and becoming rich. The rush started in 1851 when gold was found near Bathurst, New South Wales and ended with the last rush in 1893 to Kalgoorlie, Western Australia.
On February 12, 1851, a prospector discovered flecks of gold in a waterhole near Bathurst, New South Wales (NSW), Australia. Soon, even more gold was discovered in what would become the neighboring state of Victoria. This began the Australian Gold Rush, which had a profound impact on the country's national identity.
Most patients with yellow fever are asymptomatic, but among the 15% who develop severe illness, the case fatality rate is 20%–60%. Effective live-attenuated virus vaccines are available that protect against yellow fever (1).
People who do get sick will start having symptoms (e.g., fever, chills, headache, backache, and muscle aches) 3–6 days after they are infected. About 12% of people who have symptoms go on to develop serious illness: jaundice, bleeding, shock, organ failure, and sometimes death.
People aged ≥60 years may be at increased risk for serious adverse events (serious disease or, very rarely, death) following vaccination, compared with younger persons. This is particularly true if they are receiving their first yellow fever vaccination.
