A mystery illness causing headaches, fever and nosebleeds has killed five people in Tanzania as scientists race to try and identify the disease, it is reported.
Health officials have said that seven people have been found to have the illness which they have described as “strange” and has been found in the Kagera region in the northwest of the country.
Doctors are now working hard to identify and understand more about the disease which has killed five people so far.
The government’s chief medical officer Tumaini Nagu said that symptoms of the illness include fever, headaches, tiredness and nosebleeds.
A 'Rapid Response Team,' is now in place to investigate the disease.
"The government has formed a team of professionals who are part of the 'Rapid Response Team' who are investigating this unknown disease," said Ms Nagu, reported the BBC.
Authorities are urging residents in the Kagera region to remain calm and avoid contact with people who have been infected by the disease.
Last July, people suffering from similar symptoms were reported in the southern Tanzanian district of Lindi with three dying.
The illness was found to be leptospirosis, also known as Weil’s disease, which is an infection that spreads via the urine of animals including cows, pigs and rats.
Like this current mysterious illness, the symptoms include fevers and headaches while people were also vomiting, suffering swollen ankles and feet as well as seeing their skin turn a yellow colour.
The disease normally clears up quickly with antibiotics over a few days or weeks but without treatment can lead to kidney and liver failure.
Last December in the UK, dog owners were urged to keep their pets away from ponds and puddles due to toxins in the water causing illnesses like Weil's disease.
An RSPCA Knowledge Base statement reads: "Leptospirosis can cause kidney failure and liver failure, and occasionally severe lung disease and bleeding disorders.
"If you have any concerns about your pet please contact your vet as soon as possible. Leptospirosis can be treated, usually with antibiotics and supportive care.
"The chance of recovery depends on how severely the dog is affected, and how quickly they receive veterinary treatment."
