COVID-19 pandemic was first identified in December 2019 in Wuhan, China. At the end of January 2020, The World Health Organization declared a Public Health Emergency of International Concern, and later, on the 11th of March 2020, the pandemic was declared. Since then, many things have changed dramatically, many new words previously unknown became a part of our daily life. How many people have heard about lockdowns, PCR tests, Antibody tests, and travel restrictions? It is a new emerging technology. Nevertheless, vaccination campaigns have started globally. Many countries still struggle to vaccinate sufficient numbers of people to create herd immunity. Consequently, travel restrictions remain in place and new tests are created for traveling.
Two years ago, many of us could not imagine not being able to buy a ticket on a plane and to go anywhere we wanted. However, with the beginning of the pandemic, many countries have closed their borders to non-citizens and some countries such as Australia have even banned their citizens from leaving the country.
Many businesses have been hit severely by the COVID pandemic, but the airlines are one of those who suffered the most. Several airlines have ceased to exist or asked for support from the government to continue being operational. For instance, in 2020, the Italian Ernest Airlines and American Miami Air International declared bankruptcy and these are just two examples. New mutations of COVID-19 have pushed back the restart of global air travel. Moreover, the International Air Travel Association announced that air carriers will have about 41 billion dollar losses in 2021.
However, not only airlines have struggled from the pandemic. Cruise ships were particularly badly hit by the COVID-19. Moreover, due to the confined environment onboard, there was a high number of infections among crew and passengers, especially in the early stages of the pandemic. The Carnival Cruise Liner was linked to 28 deaths in Sydney and was responsible for spreading the virus in Sydney. Consequently, any cruises have been banned and there were few travel sectors hit as severely by the pandemic as the global cruise line industry. The Cruise Line International Association (CLIA) announced a loss of 10 billion dollars in 2020 with all the routes stopped to be operational for a year. CLIA had to secure 26.3 billion of investment to continue being operational.
As the world gradually returns to normal, the cruises are back to operation. Nevertheless, the full re-opening of the industry is still underway, many people were able to travel again. The cruise holidays for a long time have been dominated by people over 60 and the majority of them have already received both of their COVID vaccines and can travel again. Consequently, to prevent the spread of the virus and to make the cruises safer, the CLIA implemented new measures.
The NAB COVID-19 Test is different from the PCR Test and is used to detect neutralizing antibodies from recent or prior SARS-CoV-2 infection. The tests are not to be used to diagnose an active infection. Moreover, the test could detect the level of protection from the vaccination or recent infection.
There are around 50 different antibody tests, but the new NAB COVID-19 Test could detect the neutralizing antibodies (Nabs). Not all antibodies are neutralizing ones. Nabs do not only bind to viral antigens but also block viral infection. There are also binding antibodies, but in contrast to neutralizing antibodies, they can’t show the level of immunity from the virus. The COVID-19 Neutralizing Antibody Test is a blood test and takes just 25 minutes.
Consequently, they show the level of protection of all the people on board the cruise ships and make them unlikely to spread the virus. The vaccination campaigns are likely to revive the industry, but it is important to stay cautious. The implementation of the Nab COVID-19 Tests is a big step forward towards safer traveling.
