Introduction

In November 2002, the first case of SARS was identified in Guangdong Province, China. The virus quickly spread to multiple countries and regions. In the spring of 2003, the outbreak peaked, with over 8,000 confirmed cases reported worldwide and 774 deaths. During this period, countries implemented strict public health measures, including isolation, quarantine, and travel restrictions.

Generally, the SARS outbreak lasted from November 2002 to July 2003, spanning approximately eight months. If any abnormalities occur, it is recommended to seek medical attention promptly. The detailed analysis is as follows:

In the spring of 2003, the outbreak reached its peak, with over 8,000 cases reported worldwide and 774 deaths. During this period, countries implemented strict public health measures, including isolation, quarantine, and travel restrictions.

As prevention and control measures were enforced and research into the transmission routes of the virus advanced, the outbreak gradually came under control. By July 2003, the World Health Organization declared the end of the SARS outbreak. The duration of the outbreak primarily depended on the speed of transmission and the effectiveness of control measures; early spread occurred due to a lack of effective treatments and insufficient understanding of the virus, while later containment resulted from strengthened prevention and control efforts.

In daily life, it is important to maintain good personal hygiene habits, such as frequent handwashing, wearing masks, and avoiding close contact with infected individuals to reduce the risk of infection.

During a COVID-19 infection, the body requires substantial energy and nutrients to fight the virus and repair damaged tissues. Consuming moderate amounts of beef can provide high-quality protein, help maintain normal physiological functions, enhance immune function, and promote recovery.
