The United States Centers for Disease Control and Prevention (CDC) has designated Indonesia's COVID-19 transmission risk level as 1, or low. Indonesia, along with 29 other countries such as Bangladesh, Bhutan, and Chad, has achieved this low-risk category due to a decrease in the risk of coronavirus spread.
Indonesia's success in lowering coronavirus transmission rates is attributable to the government's intensive vaccination efforts and its call for the public to continue adhering to health protocols.
According to the CDC, 15 countries have a level 2 (moderate) transmission rate, including Argentina, Bahrain, Cameroon, and Ethiopia. The CDC has classified 56 countries as level 3 (high), among them Vietnam, South Korea, and Spain. Another 56 countries are at level 4 (very high), including Malaysia, the Netherlands, Germany, and Austria.
Meanwhile, the status of 40 countries is unknown. For these, the CDC recommends a level 4 (very high) risk, including countries such as Algeria, Yemen, Afghanistan, and Cambodia.
The CDC uses Travel Health Notices (THNs) to alert travelers and other audiences about COVID-19 transmission threats worldwide. One key criterion for assessing a country's status as a destination is its cumulative COVID-19 incidence rate over the past 28 days per 100,000 population.
Countries with an incidence rate below 50 per 100,000 population are at level 1; 50-99 per 100,000 are at level 2; 100-500 per 100,000 are at level 3; and those above 500 per 100,000 are at level 4.
