Coronavirus is mainly transmitted by droplets, so it is important to wear a medical surgical mask properly. Also maintain good personal hygiene habits, use soap or hand sanitizer, wash hands with running water, and do not wipe hands with dirty towels; wash hands immediately after contact with respiratory secretions (e.g., after sneezing). Minimize visits to crowded and closed places. Do not consume diseased animals and their products, buy chilled poultry from regular sources, and cook poultry meat and eggs and milk well. In addition, strengthening exercise, regular work and rest, and improving your immune system are the most important means to avoid being infected.
