Covid 19 Effects

In January 2020, the world was alerted to a highly infectious and deadly new virus thought to originate in Wuhan, China. This virulent strain of coronavirus or Covid 19, an extremely infectious and aggressive respiratory condition quickly became a global pandemic. Different countries across the world showed varying levels of response but were in many cases overwhelmed by its spread.

The government of Thailand initiated an extremely robust response by bringing on strict travel restrictions, border restrictions and quarantine measures.

As a direct result of this dynamic response by the Thai authorities, Thailand has some of the lowest infection rates in the world affected by the Covid 19 pandemic, with at the time of writing only 60 officially recorded deaths (circa December 2020).

Travelling to Thailand 2020-2021

Due to the current and ongoing coronavirus/Covid 19 pandemic the Thai government has introduced a range of strict measures for visitors entering the country.

Tourists and other visitors are now slowly being welcomed back to Thailand with an easing on some regulations regarding visas and entry to the country.

Thailand still maintains a strict criteria for entry to the country with requirements which include ‘fit to fly certificate (negative Covid test) prior to departure, a 2 week quarantine period in a government affiliated hotel, medical insurance/ cover, appropriate funds and various other lesser visa related regulations.

The Thai government is currently offering extended length visas and other incentives for tourists and visitors who can meet these criteria in an effort to boost the countries tourism industry.

Records showed that the stingray was a recapture from a previous tagging expedition with Dr. Zeb Hogan and National Geographic which had grown significantly in the six-year period between captures.
