COVID-19 Map: List of all the countries in the world affected by Coronavirus
In a piece of good news, there are several countries where no positive coronavirus cases have been reported. As per the data collected by John Hopkins University, 18 out of the 193 United Nations-member countries claim to be coronavirus-free. Here is the list of 18 countries which have not reported any positive COVID-19 case so far:

- Micronesia
- Nauru
- North Korea
- Palau
- Samoa
- Sao Tome and Principe
- Solomon Islands
- Tajikistan
- Tonga
- Turkmenistan
- Tuvalu
- Vanuatu
- Yemen
- South Sudan
These are the countries that have not reported confirmed COVID-19 cases so far. The reasons may vary. It can be said that these countries may not have reported the cases and it can be presumed that they are lying. Another reason could be the lack of proper health facilities (many countries may not have tested their people for coronavirus, have a lack of medical professionals, hospitals, testing kits, etc.)
Out of these 18 countries, many countries are very small in areas or have a lesser population- social isolation could be a part of people's lives here. While other countries have fewer tourists every year, this implies that these countries have a lesser chance of getting infected compared to countries having more tourists every year. As per WTO ( World Tourism Organization), many of these countries are the least visited countries in the world.
As per some reports, many of these countries have taken precautionary measures such as sealing the borders, cancelling flights, etc. way before any positive COVID-19 case.
