The Assistant Undersecretary of Ministry of Health for Preventive Health and Member of the Scientific Committee of Infectious Diseases Dr. Abdullah Al-Asiri pointed out that the Committee affirmed that the virus Corona does not spread easily between humans and requires direct contact with an infected pneumonia patient, and therefore no cases have observed associated with human crowds such as Hajj, Umrah or in schools and football stadiums. Asked on the impact of a climate change in the Kingdom on the increasing numbers of Corona infections, he said that this is not yet clear, adding "We have faced an increase in the number of cases around the same time last year at the end of winter". On the reason for the return of Corona virus during this period, Dr. Al-Asiri said that the virus has not disappeared at all in order to return, there are cases recorded every month and announced when they are confirmed. In reply to a question, he stressed that no hospital has been actually closed in Jeddah due to a virus Corona, but there has been coordination for directing some ambulatory cases to other hospitals. He noted that the development of vaccination against Corona viruses is difficult in terms of technology and the current efforts focus on prevention and assessment of available treatment methods.
