The world's "interconnected society" nature could result in having more outbreaks even if the present outbreak is controlled. This is according to Lawrence Gostin, a professor of public health at Johns Hopkins University.

Since interconnectivity is the nature of the world, both Europe and the United States could face several more waves of the COVID-19 outbreak. 

Gostin explained that COVID-19 is just starting through the Subsaharan Africa and then through the Indian subcontinent. In any case that the outbreak grew uncontrolled in these under-developed regions, the novel coronavirus may find its way back again to the US and Europe. This could grow to a third wave and even a fourth wave even among the developed countries.  

"Even if the United States and Europe were to get their COVID epidemics under control, if you have got COVID raging in other parts of the world, in this interconnected society it will come back to Europe and the United States," Gostin said in an interview with BBC radio. 

Indeed, there are now more than 1 million people in Europe who are infected with the virus. More than 50% of those confirmed cases are in Italy, Spain, Germany, and France.   Together, these four European countries made up a quarter of the world's overall infections.

As of Wednesday night, Spain has 180,659 confirmed cases, Italy has 165,155, Germany has 134,753, France has 134,582, and the United Kingdom has 99,489. Also, around 14 more countries recorded more than 10,000 confirmed cases. These figures are from Johns Hopkins University. 

With regard to the number of deaths, however, Germany has the lowest number. In fact, the country's ratio between confirmed cases and deaths impressed the world. Germany only has 3,804 deaths as of Wednesday night. 

Italy, so far, has the highest recorded deaths in Europe at 21,645. Spain has 18,812 deaths, France has 17,167, the UK has 12,868. 

In the US, there are now 637,000 infected people and 28,364 people who died. The country recorded its highest number of COVID-19 deaths on Tuesday at 2,405.
