Greenhouse gas emissions that cause negative influence

Greenhouse gases are chemical compounds that contribute to the greenhouse effect by allowing solar radiation to enter the earth’s atmosphere where it warms the earth’s surface and is reradiated back into the atmosphere as longer wave heat energy. These gases absorb this heat and trap it in the lower atmosphere (Reay, 2008). This phenomenon has had adverse effects on the global climate which in turn directly effects the human population.

Classical dengue fever

Dengue fever is caused by RNA containing arbo viruses (Arthropod born viruses) of flavi virus group. The four distinct, but closely related viruses which cause dengue fever are mosquito borne flavi-ribo viruses of family Flaviviridae. Dengue fever is also known as the Break bone Fever. Mode of transmission The viruses of dengue fever are transmitted to humans through the bites of infective female Aedes aegypti (mosquito). Mosquitoes generally acquire the virus while feeding on the blood of an infected person. After virus incubation for 8-10days, an infected mosquito is capable of transmitting the virus.
