  Influenza or the flu is a contagious  viral infection that attacks your nose  throat  and lungs  it can cause fever  chills runny nose sore throat  cough muscle aches and fatigue the flu  the virus is extremely small and only  visible through electron microscopes  inside the virus genetic material contains  the  information to make more  copies of the same virus a protein shell  provides a hard protective enclosure for  the genetic material as the virus  travels between the people or animals it  infects an outer envelope allows the  virus to infect cells by merging with  the cell's outer membrane projecting  from the envelope are spikes of protein  molecules the flu virus uses its h  spikes like a key to get inside your  cells n spikes allow copies of the virus  to break away from your infected cells  to infect more cells there are 17 known  types of H spik...

Ebola virus disease is a severe and usually fatal illness in humans and  other primates caused by the Ebola virus  the condition which was formerly  referred to as Ebola hemorrhagic fever  has a high risk of death killing between  25% and 90% of people who are affected  in 1976 the disease was first identified  in two simultaneous outbreaks one in  Zahra a town in South Sudan and the  other in the young Baku Democratic Republic  of Congo a village near the Ebola River  from which the name of the disease was  coined the largest and more complex  epidemic outbreak of this condition  occurred in 2014 through 2016 in some  part of West Africa with 28,000 616  cases and 11,000 310 deaths the outbreak  mainly affected three countries in West Africa Liberia Guinea and Sierra Leone  some cases were also reported in some  parts of central Africa Ebola virus disease  spread between these  coun...

This is SARS CoV-2.  It belongs to the family of coronaviruses,  named for crownlike spikes  on their surfaces.  SARS CoV-2 can cause COVID-19,  a contagious viral infection  that attacks primarily your throat and lungs.  What actually happens in your body  when you contract the coronavirus?  What exactly causes your body  to develop pneumonia?  And how would a vaccine work?  The coronavirus must infect living cells  to reproduce.  Let's have a closer look.  Inside the virus,  genetic material contains the information  to make more copies of itself.  A protein shell provides a hard protective  enclosure for the genetic material  as the virus travels between  the people it infects.  An outer envelope allows the virus  to infect cells by merging with  the cell's outer membrane.  Projecting from the envelope are  spikes of protein molecules.  Both a typical...

What is CORONA VIRUS?  So the whole family of coronaviruses are named Coronavirus  because corona means a crown, and so this refers  to the way that the virus looks under the microscope  like there's a crown on the top of the virus.  Some of them, four or five different kinds,  cause common diseases among humans,  everything from the common cold  to mild or moderate respiratory illnesses.  Other kinds of coronaviruses affect animals,  and sometimes, on rare occasions, we see coronaviruses jump  from animal species into the human population. WHY THIS ONE IS GETTING SO MUCH ATTENTION? The 2019 novel coronavirus is getting a lot of attention now  because it is a new kind of coronavirus  we haven't seen among humans before.  The theory is that it may have jumped from an animal species  into the human population, and then begun spreading. scientists  have seen some people that have died of this disease,  and...
