specialized doctors
"Yellow" cannot be predicted after "Ebola" was innocent of the death of the citizen Muhammad Daoud (Jeddah). Specialized doctors confirmed to Okaz that identifying the type and virus of the disease that killed a citizen who visited Sierra Leone, which is witnessing the spread of the "Ebola" virus, and the reasons for his death are still in terms of The medical department is not specific and vague and needs time to determine the type of virus at the same time, at a time when the Ministry of Health indicated that the initial examinations of the samples of the deceased citizen were negative, indicating that identifying the disease that killed his life requires more accurate and advanced additional examinations from the laboratories of the «Center for Disease Control and Prevention. »In Atlanta, USA, besides the results of the second sample test for the same case, which was sent to one of the accredited German laboratories.
Virus identification
The director of the Saudi Society for Infectious Diseases and Microbiology in the Western Region, Dr. Nizar Bahabri, says, “There are many and deadly viruses present and spread in the region, including yellow fever, Lava fever, and several other viruses, and as long as the initial tests showed that the citizen did not die of Ebola, other analyzes will definitely prove the result,” he added. : «From a medical point of view, it is known that laboratory analyzes of viruses are carried out separately, for example when placing the compound DNA on a part of the sample that was taken from the patient, the analysis reveals a specific disease, and identifying the disease needs more time if the result does not show that he is infected with Ebola Or yellow fever, it may be a new, unknown virus, and some believe that identifying some pathogenic viruses can be done within a day or two, and this is not correct, as some unknown samples of the type of virus or bacteria need a laboratory culture, and thus the need for more time to determine the accuracy the disease".
He indicated that the Ministry of Health has made great efforts in this aspect, and benefited from the experience of the spread of Corona, and took all preventive and precautionary steps to prevent the spread of Ebola disease, including banning Umrah and Hajj visas from those countries affected by the disease, and taking more preventive precautions in the air and sea ports, as it dealt with The citizen''s condition according to scientific steps, from the discovery of his injury until his burial.
Dr. Bahabri emphasized that prevention remains the most important step in avoiding exposure to any viral or contagious disease, as it is related to awareness and behaviors, all of which aim to prevent the infection from transmitting from the infected to the healthy.
Hemorrhagic viruses
As for the head of the department of viruses and partial analysis and a consultant of medical viruses at King Fahd Hospital in Jazan, Professor Zaki Munawar, he pointed out that the problem of viral hemorrhagic fevers is similar in the initial symptoms, so it is not possible to determine the type of virus except by conducting laboratory tests on most diseases that cause an individual''s infection. Especially since Africa has been endemic to some viral hemorrhagic diseases such as Ebola, Rift Valley fever, yellow fever and dengue, indicating that it is not possible to predict whether a citizen will be infected with yellow fever or any hemorrhagic virus unless the virus is laboratory determined.
Yellow fever
For his part, Dr. Mansour Al-Tubaigy, Director of Patient Safety at the Maternity and Children Hospital, said: “Since the infection has not been identified with Ebola, it takes time to determine the type of virus, and it is not possible to alert it to yellow fever, as it is known that there are strains of viruses that have been endemic for years, including Ebola, Congo, Crimean fever, malaria, yellow fever and other hemorrhagic fevers, and the determinant of the disease will definitely be the analyzes that are conducted on the samples.
On the delay in announcing the results of some of the analyzes that are conducted on some samples, he said, "Some samples need to conduct a laboratory culture, which requires more time to determine the type of virus, and hence, identifying it and the type of infection with it requires accuracy and more time."
He added that yellow fever is a viral disease that may be fatal. It infects humans and monkeys and is transmitted by the bites of female mosquitoes of the type "positive hands" when a person or a monkey is infected with the disease. The monkeys that live in the jungle constitute a source of disease transmission, and the disease spreads in African countries and South America. And the vaccine used in the yellow fever vaccination is an effective vaccine made from the live attenuated yellow fever virus, which stimulates the body to produce antibodies to the virus, thus preventing the emergence of the disease.
