Temperature checks are commonly used in some countries as part of their strategies to combat the disease. According to the Centers for Disease Control and Prevention, coronavirus symptoms can develop anywhere between two and 14 days after exposure — meaning someone can have the virus and not know it. After someone is infected the virus will multiply in their body until it reaches a critical level, which causes the body to respond with symptoms. This briefing from Irwin Mitchell offers guidance to organisations who are considering using temperature checks.
