"...Không nên có thái độ cư xử xa lánh kì thị với người bị nhiễm bệnh. Nếu như sợ có thể bị nhiễm bệnh thì ta nên tránh tiếp xúc với họ nhưng vẫn phải tôn trọng người bệnh. Ngoài những biện pháp trên ta cũng có thể giúp những người lớn tuổi, trẻ em, những người ít tiếp xúc với công nghệ thông tin hoặc những người hiểu sai về bệnh dịch này hiểu rõ hơn và giúp họ tìm cách phòng chống.
Mặt khác, nên phê phán tố cáo những người có hành vi lợi dụng dịch bệnh để trục lợi hay những người có hành vi tung tin nói sai sự thật khiến người dân hoang mang lo lắng.
Có thể nói đây là một trong những đại nạn của nhân loại, là khoảng thời gian con người lo sợ bất an nhất. Nhưng cũng là khoảng thời gian ta đồng lòng đoàn kết cùng nắm tay nhau để đẩy lùi đại dịch bệnh này...Hãy luôn vững tin vào một ngày mai tươi sáng cho những nạn nhân của bệnh dịch virus corona"
