Descriptions Influenza Virus (Bird-Human) transmission Influenza viruses have viral envelopes covering their protein capsids. The virus envelopes are derived from host cell membrane and viral glycoprotein. Functionally‚ viral envelopes are essential for entry into host cells. lipids are involve in attachment ‚signaling‚ replication and budding processes. During transmission even if the virus transmit from eukaryotic to eukaryotes cells the attachment of virus to the host cell may be different

Respiratory syncytial virus (RSV) Introduction of the Lungs: The primary role of our respiratory system is the exchange of gases in our blood stream. As we inhale our lungs take in Oxygen (O2)‚ as we exhale our lungs release Carbon Dioxide (CO2). The major parts of the respiratory system consist of; The upper respiratory tract consists of the nose‚ sinuses‚ mouth‚ larynx and throat. The lower respiratory tract consists of trachea‚ bronchial tubes and the lungs. The right lung

Humans are the major hosts of the dengue virus and Aedes aegypti mosquitoes represent the principal vector .A aegypti is closely associated with human habitation and its larvae are often found in artificial water containers such as discarded tires‚ buckets and water storage facilities. Dengue is a mosquito borne disease that has recently become a public health concern. The WHO has estimated that 40% of the world’s

INTRODUCTION Dengue Fever is caused by one of the four closely related‚ but antigenically distinct‚ virus serotypes Dengue type 1‚ Dengue type 2‚ Dengue type 3‚ and Dengue type 4 of the genus Flavivirus and Chikungunya virus. Infection with one of these serotype provides immunity to only that serotype of life‚ to a person living in a Dengue-endemic area can have more than one Dengue infection during their lifetime. Dengue fever through the four different Dengue serotypes are maintained in the
