On March 5, 2017, a man in his 50s, who was infected with Kaposi sarorga (KS), was taken to the city’s main hospital.
The hospital did not immediately offer a diagnosis or an expected date for his return.
Instead, they referred him to a specialist for further tests.
The specialist’s report, prepared by the city and confirmed by a public health official, suggested that the man had KS.
He was given a diagnosis of KS and was transferred to a unit at the city morgue, where he underwent a blood transfusion.
“He’s in very good health,” the city official said, “and has no symptoms.”
The man, whose identity has not been revealed, had the virus in his blood, and he was discharged the following day.
Two weeks later, he was diagnosed with KS again.
“The patient is receiving the usual treatment, and we don’t think there is any reason to change the treatment,” said the city public health officer, who declined to be identified.
The public health specialist also declined to provide further details about the man’s case, citing a strict embargo imposed by the authorities.
But there are several theories as to why the man was not treated sooner.
One theory is that the virus was already circulating in the city.
“It is possible that a case of KS is more likely to develop if the city is already infected,” said Dr. Yousif Sattar, a professor of epidemiology and biostatistics at Cairo University.
Another theory is the man is not yet infected and has already been exposed to the virus.
“We don’t have any evidence of that yet,” he said.
It is impossible to know with certainty if KS is spreading because the virus is circulating in large numbers, said Dr Yousisia Zareb, a research associate at Cairo’s University of Medicine and Science and a specialist in infectious diseases.
“If we had a high level of transmission, we would expect the virus to spread through all the city,” she said.
Sattara and Zarep said it would be important to monitor the patient’s condition to see if the virus has already entered his bloodstream.
He said he would take the patient to a clinic in the western suburbs of Cairo for further testing and possibly to a hospital, if necessary.
There are also concerns about the possibility that the infection is spreading among relatives of the man.
“There is a concern about spreading between relatives of those who are ill, so we should take care of them and be careful,” said Zarem.
But while this seems like a likely scenario, it is not the only one.
“In some countries, the disease is known to be transmitted via the indirect transmission of virus through close contact,” said Sattaria.
“But in other countries, it’s not known to have been transmitted through direct contact.”
Sattari said that there are two main reasons why this has not happened in Cairo: The first is that a large number of people in the area, and even in the medical facilities, are not vaccinated against the disease.
“That is why we are not seeing the virus being transmitted,” he added.
“Secondly, there are other reasons, such as that the country is relatively low in the case count, or because it has been operating under a state of emergency, or that people in other cities are not vaccinating their own children,” said Youssef Aboghi, director of the Egyptian Centre for Infectious Diseases Research and Teaching, a non-profit organisation based in Cairo.
The latter, he said, could explain why the virus may have not spread as far as it did.
It’s not clear why the cases are not being reported, or whether they are being hidden or kept under wraps.
“This is a serious problem,” said Aboghi, adding that the number of cases is rising rapidly.
The country has the highest number of confirmed cases in the world, with over 13,000 cases and an additional 13,600 cases confirmed.
In a recent survey of health experts in Egypt, only one in five doctors in the country had seen a case, and only 3% of doctors have seen any cases.
The situation is especially difficult in rural areas where the majority of cases occur.
“Most rural communities are living in fear and in extreme poverty,” said Salah Abou Atef, a researcher at the Egyptian Medical Association, a federation of health care professionals.
“Every day, we see more and more people who have to leave their homes and leave the hospital for work, and they have to stay at home because they don’t know where to go.”
It’s unclear how widespread the infection in Egypt is, or how the man has avoided catching the virus because he has not yet received a blood test or a vaccination.
