**Key Considerations & Tips for your choice:**

* **Your Blog’s Audience:** Who are you writing for? If they’re very tech-savvy and well-informed, you can be more technical. If they’re a general audience, stick to simpler language.
* **Blog’s Content:** Tailor your description to the type of content you usually post. If you focus on travel during the pandemic, mention that. If solely focused on prevention, include keywords about prevention.
* **Search Engine Optimization (SEO):** Include relevant keywords that people might search for. “COVID-19” is a must, but consider variations like “新型冠狀病毒” (New Coronavirus), “防疫” (Disease prevention) or specific symptoms related content.
* **Keep it concise:** WordPress’s tag descriptions are best kept short and to the point.
