The pandemic, which began two years ago, has resulted in several travel and daily living limitations. China and certain regions of Europe are seeing a new surge in cases, headed by the BA.2 type of Omicron, raising new concerns about the global spike in infections. Shanghai, China, is currently the worst-affected city, with over 4,400 cases reported. India, on the other hand, is seeing a significant decrease in Covid cases. The US Centers for Disease Control and Prevention (CDC) reduced its COVID-19 travel recommendations for India on Monday, citing a drop in coronavirus incidence in India. The Centers for Disease Control and Prevention (CDC) downgraded India from Level 3 (high risk) to Level 1 (low risk).

“The Centers for Disease Control and Prevention (CDC) has issued a Level 1 Travel Health Notice due to COVID-19, suggesting a low level of COVID-19 in the country,” the US government stated in a statement. If you are fully immunized with an FDA-approved vaccine, your chances of catching COVID-19 and experiencing severe symptoms may be reduced.” “Please study the CDC’s particular advice for vaccinated and unvaccinated travelers before planning any foreign travel,” it continued.

The Centers for Disease Control and Prevention (CDC) issues Travel Health Notices (THNs) to warn travelers about health risks throughout the world and provide advice on how to stay safe. For countries, the CDC has four categories of Covid-19 travel advisories.

Here’s everything you need know about them:

Level 1 (low risk)

As the name implies, level 1 CDC guidelines cover countries with a low Covid risk. The CDC encourages travelers to make sure they are “completely vaccinated before traveling to these destinations,” according to the advice. There are currently approximately 30 countries in this category, including India, China, Kenya, Ethiopia, Nigeria, Taiwan, and Uganda.

Level 2 (Moderate Risk)

The second level comprises countries that have been moderately affected by the pandemic. The guideline recommends that travelers be completely vaccinated in this group, and that individuals who are unvaccinated face a “increased risk of serious disease” should avoid non-essential travel. The Bahamas, Bangladesh, Ghana, Guinea-Bissau, Jamaica, Kyrgyzstan, Malawi, Montserrat, Morocco, Nepal, Pakistan, Philippines, Saint Kitts & Nevis, and Zambia are among the 14 countries included in this category.

Level 3 (High-risk)

This level includes high-risk countries or those that have been severely affected by Covid-19. All unvaccinated travelers are recommended to avoid non-essential travel in this category. Albania, Cuba, Botswana, Fiji, Ecuador, Indonesia, Peru, Qatar, South Africa, Sri Lanka, and the United Arab Emirates are among the countries in this group.

Level 4 (Very High-Risk)

Countries that have been badly affected by the coronavirus are classified as Level 4 in the CDC guidelines. The Centers for Disease Control and Prevention (CDC) urges travelers to stay away from these nations entirely. Argentina, Australia, Austria, Azerbaijan, Bahrain, Belgium, Brazil, Canada, Chile, Denmark, Egypt, France, Germany, Hong Kong, Iran, Iraq, Ireland, Malaysia, Maldives, South Korea, Spain, and the United Kingdom are among the countries that fall within this group.

Level Unknown

In its list of travel health notices, the US agency includes another ‘unknown’ level. This comprises nations where the data for the Covid-19 cases is incomplete. This category includes countries like North Korea, Afghanistan, Syria, and Yemen. The Centers for Disease Control and Prevention urges travelers to avoid visiting these locations.

Meanwhile, the United States, which was the hardest impacted by the Covid-19, has reported over 81,658,973 cases and 1,004,244 deaths.
