Basically every year 1 billion people get infected by influenza causing extreme resource shortages still it is getting better to keep the death count down with vaccines but still its potential is still very dangerous and is not quite contained. Along with the super k version of influenza causing a spike in cases globally now. I still think that we need better protection against certain diseases so the resources are not drained globally. Perhaps we can use tricorder like devices on our phones that essentially heal us from diseases which I believe radio nanotransfection could lead to breakthroughs in the future.

Influenza, or the flu, is both a seasonal and a pandemic virus. Every year, mainly during the winter season, seasonal influenza infects as many as 1 billion people. This makes it one of the most common infectious respiratory viruses, after the common cold. Thankfully, the WHO Global Influenza Surveillance and Response System, or GISRS, monitors what viruses are circulating and twice a year recommends which viruses to target in the flu vaccine for the upcoming season. The flu vaccine is the best way to prevent infection and may reduce symptoms if you do get the flu. For those who are more vulnerable to flu, what we call ‘high risk groups’, the vaccine can save your life. Good hygiene practices can also reduce the risk of infection (for more information, see the factsheet here ). Thankfully, although there are hundreds of millions of cases every year, the vast majority of these are not serious. Nevertheless, WHO estimates that there are 3 to 5 million cases of severe illness and between 290 000 to 650 000 respiratory deaths annually.
