A second person has been diagnosed with the deadly monkeypox virus in England, just a few days after the first case was revealed.
The unidentified patient had recently been to Nigeria, where they are understood to have picked up the disease.
Initial symptoms include "fever, headache, aching muscles, backache, swollen lymph nodes, chills and exhaustion", says the i news site.
It is contacting individuals who have been in close contact with the infected patients as a precautionary measure.
"We are working hard to contact individuals, including healthcare workers, that might have come into contact with the individual to provide information and health advice".More news: Artificial Intelligence Helps Astronomers Locate Fast Radio Bursts

Only 113 of the cases reported were confirmed to be monkeypox across 16 states, mostly from states in the south-south. The first recorded case in humans was in 1970 in the Democratic Republic of Congo. A rash may also develop, which usually begins on the face and then spreads to other parts of the body.
Dr Mike Beadsworth, clinical director of the Tropical and Infectious Diseases Unit at the Royal Liverpool University Hospital, a specialist centre in respiratory infectious diseases, said: 'We are treating a patient who has tested positive for monkeypox.
Although monkeypox and smallpox have similar symptoms, monkeypox is less deadly than smallpox: In previous outbreaks, the fatality rate for monkeypox has been between 1 percent and 10 percent, World Health Organization said.
For most persons who have been exposed to monkeypox, the risks are greater than the risks from the smallpox vaccine.
The monkeypox virus was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research, says the United Kingdom government website's infectious diseases portal.
He added that although the overall risk to the general public is very low, it is odd that two cases arose in such a short period of time.
Monkeypox does not spread easily between people and most who contract the infection recover within a few weeks, though severe illness can occure in some people. The lesions progress to become small, fluid-filled blisters before scabbing over and falling off.
Symptoms generally appear within ten days of exposure to the virus and can last for between two and five weeks.
