Conjunctivitis is a common and uncomfortable eye condition that can be caused by infections, allergies or irritants. The conjunctiva is thin clear tissue covering the front of the eye. One or both eyes may be affected, and the condition can spread from one to the other.
I'm assuming that by America you mean The United States. There's no country called America. Even when excluding Taiwan and other disputed territories, China is larger than the United States, both in terms of land area, and in terms of land area including inland waterbodies. By land area only: China: 9,326,410 sq km. United States: 9,161,966 sq km, 1.8% smaller than China.
Russia is the worldâs biggest country by land area, while the United States is either the third or the fourth largest (Chinaâs claims to territories disputed by other countries, especially India, will determine which of the two countries is bigger than the other), with 17,098,242 sqm and 9,826,675 sqm, respectively.
