Notice on the requirement for two nucleic acid tests instead of "nucleic acid + serum IgM antibody" tests for the purpose of applying for a Health Code for China-bound travelers who have received COVID-19 vaccination as well as updates on other relevant requirements for travel to China
2022-01-14 22:05

With the rapid spread of the "Omicron" variantof Covid, the global epidemic situation of COVID-19 has become increasingly severe and the risk of cross-infection during international travel is growing. The Chinese Embassy in Bulgaria once again reminds everyone to continue to adhere to the principle of "no travelunless necessary" and try to avoid long-distance or cross-border travel.

To ensure the safety of travelers and reduce chances of cross-border transmission, beginning January 20, 2022, the Chinese Embassy in Bulgaria will implement adjusted requirements for the application of the Health Code for travelers from Bulgaria to China via a third country.   One of the most important adjustments is the requirement for peoplewho have received COVID-19 vaccination to take two nucleic acidtests instead of the "nucleic acid + serum IgM antibody" tests.Other adjustments have also been highlighted in this notice.  In case of inconsistency with previously issued notices or supplementary explanations relating to the Health Code application,  this notice shall prevail.

1. Definition of “Traveler from Bulgaria”

A traveler from Bulgaria is one of the following:

(1) A long-term resident in Bulgaria,who holds a Bulgarian passport, ID card, residence card, or residence certificate issued bythe Bulgarian governmentinstitutions, and who has  stayed in Bulgaria for more than 28 days before applying for a Health Code.

(2) A short-term resident in Bulgaria, who has entered Bulgaria with a visa, and has stayed in Bulgaria for more than 28 days before applying for a Health Code.

2. Transit requirements

There is no direct flightbetween Bulgaria and China. All travelers from Bulgaria to China via a third country are only allowed to transit once, i.e. Bulgariaa transit countryChina.    Otherwise, a Health Code will not be issued.

If necessary, you mayenter the transitcountry, but the transit time is not recommended to exceed 48 hours. If you travel from Bulgaria and enter the transit country by plane, train, bus, or car, you must go directly to the transit countrywithout transiting through or staying in another country on the route.

When transiting ina thirdcountry, you must takea test at the transit country as required and apply for a Health Codefrom the Chinese embassy or consulate in thatcountry before continuingyour travel to China. Please note that some transit locationshave recently adjusted the requirements for transit to China. Please makesure to check in time the notices of Chineseembassies orconsulates in transit countries and relevant airlines onthe specific requirements in order to avoid hindranceto the travel. The Health Codeissued by the ChineseEmbassyin Bulgaria can only be used atBulgarianairports, and its validity does not cover anyflight departing fromthe transit country. It is recommended that the applicant take a screenshotof the Health Coderightafter receiving it. It may be required by the Chinese embassy or consulate in the transit country.

3. Pre-departure quarantine

Everyone who goes to China should strictly observe indoor quarantine and self-health monitoring for 14 days before departing Bulgaria, without going out except for necessary tests, and should complete the "Self-Health Monitoring Form" (see Annex 1) as required.

4. Testing requirementsfor travelers under different circumstances

(1) Unvaccinated persons

All travelers to Chinafrom Bulgaria, who are not vaccinated, should take a nucleic acid test and a serum IgM antibody test at an Embassy-designated testing labwithin 48 hours prior to the first leg of the travel itinerary.

They may apply for a Health Code from the Chinese Embassy in Bulgaria if the results of the tests of PCR, IgM antibody, or IgG antibody (if included in the antibody test report)  are negative. 

If the result of any one of the tests of PCR, IgM antibody, or IgG antibody (if included in the antibody test report) is positive, you will be considered “a person with a history of infection”.

Nucleic acid tests must be performed on the 1st, 4th, and 7th day of the monitoring period. If the results are all negative, you can then apply for a Health Code with negative reportsof two PCRtests ( if you are vaccinated), or negative reports of PCR and IgM tests (if you have not been vaccinated) within 48 hours before boarding after the end of the quarantine.

(6) Ship crews disembarked in Bulgaria

Ship crews who have disembarked in Bulgaria and intend to travel to China should be quarantined indoors for at least 14 days in Bulgaria.
