Following the outbreak of Hantavirus, U. S. health officials have issued a health alert to 39 other countries as well. They have sent warnings to these countries stating that if any of their citizens have stayed in Yosemite National Park tent cabins this summer season, then there are chances that they might got exposed to this deadly mouse-borne Hantavirus.

In total, 10,000 people seem to be at risk of constricting this pulmonary syndrome, as all of them lived in Yosemite between the months of June and August this year.

As told by Dr. David Wong to Reuters in an interview, around 2,500 individuals even lived outside the United States.

Most of the countries on red alert belong to the European Union.

Hantavirus is a lung disease. It has no cure but if it is diagnosed at an early stage through blood tests, then survival rates increase to a great extent.

Till now it has taken the lives of two innocents and four other people are still in danger. All of them are U. S. citizens.

The most important thing that is concerning the officials is that if visit to this park is not banned immediately then there is a risk of many more people developing this lung disease in the next month or so.
