It is important that each and every one of us take the necessary steps to prevent the spread of the virus, so I think I too will be careful.
ご質問ありがとうございます。
"It is important that each and every one of us take the necessary steps"=「一人ひとりが必要な対策を取ることが大事である」
"to prevent the spread of the virus,"=「ウィルスの拡散を防ぐために」
"so I think I too will be careful."=「なので私も気を付けようと思う。」
ご参考に。
Since individual prevention measures are important, I also plan to be careful.
「一人ひとりの感染対策が大切なので私も気を付けようと思う」は、「Since individual prevention measures are important, I also plan to be careful.」と表現できます。
「individual prevention measures」は「一人ひとりの感染対策」や「個々の予防対策」を意味し、「plan to be careful」は「気を付けようと思う」という意思を伝えます。
