Severe Acute Respiratory Syndrome (SARS) epidemic illustrated the crucial role of infection surveillance and control measures in the combat of any highly transmissible disease. We conducted an interview survey of 121 medical staff 145 doctors, 46 staff nurses and 30 medical assistants) in a state hospital in Malaysia three months after the end of SARS epidemic (from October to December 2003). Staff was grouped according to those directly involved in the care of suspected SARS patients [S+ group n=41] and those who were not [S- group; n=80]. On hand washing following sneezing, coughing and touching patients, the proportions of medical staff that reported an increase after the SARS crisis were 22.3%, 16.5% and 45.5% respectively. On wearing masks, gloves, and aprons when meeting potentially infectious patients, the proportions that reported an increase were 39.7%, 47.1% and 32.2% respectively. Significantly more staff in S+ than S- group reported these increases. Sixty percent of staff was aware of changes in hospital infection control policies after SARS; 93.4% was aware of notifying procedures, and 81.8% was aware of whom to notify in the hospital. Regarding infection isolation ward, Infectious Control Nurse and Infection Control Committee Chairman in the hospital, the proportions of staff that could correctly name them were 39.7%, 38.3% and 15.7% respectively. Significantly more in S+ than S- group could do so. However, more than half the staff claimed ignorance on the knowledge of infection isolation ward (56.2%), Infection Control Nurse (57.9%) and Chairman (65.3%). Our findings demonstrated that SARS crisis had some positive impact on the infection control practices and awareness of medical staff especially on those with direct SARS involvement. Implications for future control of infectious diseases are obvious.

Severe acute respiratory syndrome (SARS) reminds us that sudden disease emergence is a permanent part of our world--and should be anticipated in our planning. Historically the emergence of new diseases has had little or no impact beyond a small, localized cluster of infections. However, given just the right conditions, a highly virulent pathogen can suddenly spread across time and space with massive consequences, as has occurred on several occasions in human history. In the wake of the SARS outbreak, we are now forced to confront the unpleasant fact that human activities are increasing the frequency and severity of these kinds of emergences. The idea of more frequent biological "invasions" with economic and societal impacts comparable to SARS, presents stakeholders in and the global economy with unprecedented new risks, challenges and even opportunities. As a major contributor to economic stability, the insurance industry must follow these trends very closely and develop scenarios to anticipate these events.

The recent outbreak of the novel coronavirus disease, COVID-19, has highlighted the threat that highly pathogenic coronaviruses have on global health security and the imminent need to design an effective vaccine for prevention purposes. Although several attempts have been made to develop vaccines against human coronavirus infections since the emergence of Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) in 2003, there is no available licensed vaccine yet. A better understanding of previous coronavirus vaccine studies may help to design a vaccine for the newly emerged virus, SARS-CoV-2, that may also cover other pathogenic coronaviruses as a potentially universal vaccine. In general, coronavirus spike protein is the major antigen for the vaccine design as it can induce neutralizing antibodies and protective immunity. By considering the high genetic similarity between SARS-CoV and SARS-CoV-2, here, protective immunity against SARS-CoV spike subunit vaccine candidates in animal models has been reviewed to gain advances that can facilitate coronavirus vaccine development in the near future.
