'Stay home when sick' advice: implications for sport and exercise

Area of Science:

• Sports Medicine
• Public Health
• Infectious Disease Epidemiology

Background:

• The coronavirus pandemic highlighted the risks of respiratory illness spread.
• Young athletes, while less vulnerable than the elderly, can still experience severe outcomes from viral infections.
• Traditional athletic culture often encourages training and competing while ill due to event pressures and team obligations.

Purpose of the Study:

• To emphasize the importance of individual and public health strategies in preventing respiratory illness transmission within athletic communities.
• To advocate for a cultural shift in sports, promoting the 'stay home when sick' principle.
• To address the risks of chronic fatigue and myocarditis in athletes experiencing viral illnesses.

Main Methods:

• Review of existing data and public health knowledge regarding respiratory virus transmission.
• Analysis of the correlation between respiratory and cardiovascular deaths in different countries during the pandemic.
• Discussion of the ethical and health considerations for athletes participating in sports while ill.

Main Results:

• Respiratory viruses are linked to cardiovascular deaths, as evidenced by correlating death rates in countries with varying COVID-19 prevalence.
• While young athletes have a lower risk of severe illness, they are not immune to complications such as myocarditis or overtraining-induced chronic fatigue.
• The pandemic has increased awareness of public health responsibilities in mitigating the spread of infectious diseases.

Conclusions:

• A 'stay home when sick' policy is a sensible individual strategy for athletes to mitigate personal health risks.
• Promoting a culture where staying home when sick is considered the 'right thing to do' is crucial for protecting vulnerable populations.
• Integrating public health obligations into sports culture can help prevent the spread of respiratory illnesses and safeguard community health.
