Present time we are listening about Havan syndrome in newspapers. 

Before talk about Havana syndrome we need to know about National Academy of sciences (NAS).

The National Academy of Sciences (NAS) is a United States (US) nonprofit, non-governmental organization. It is established under Act in 1863. NAS submit there science and technology related report on US government.

Now let's talk about Havana Syndrome.

NAS submitted a report to US government in 2020. According to this report Directed Microwave Radiation is a reason of Havana syndrome. Havana syndrome is a Mass psychogenic illness. 

Now let's talk about Mass psychogenic illness.

When a collective group of people felling illness at same time. And If there problems are not related to physical or environment reason. They feels that there illness is related to bacteria or other poisonous substance. Then it is called Mass psychogenic illness. 

Havana syndrome case started from Havana in 2016. It is capital of Cuba. Some American (US) diplomats and employees of US deployed in Havana. There are some US officials face a problem of hearing and other issues.

US government said that it is sonic attack and attacked by Cuba. But Cuba government denied that statement.

Havana syndrome is a Microwave weapon according to National Academy of sciences.

Now let's talk about Microwave Radiation weapons.

It is direct energy weapons. Sound, LASER, Microwave Radiation are use as a weapon in microwave radiation weapons. 

 there are create a sensetive to a human body from high frequency electric magnetic radiation in microwave radiation weapons.

Microwave are excited the water molecules  and vibrate the molecules which available in  food. There are increase the temperature due to vibration. And human beings are face the issue of hearing problem and other issues. 

Microwave weapons are weapon which impact on human beings without any physical spot of body. And it's impact is long duration.

Let's talk about Microwave weapon technology development trend.

China developed a microwave weapon  “W B- 1” in 2014.

US developed a “Active denial system” which is prototype of microwave weapon.

DRDO will ready for new weapon which “Directive Energy Weapon”. This weapon is based on high energy LASER and microwave.

Now technology advancement increase the competition among countries for weapon. New weapon technology is threat for humanity. So United Nations and countries are need to take a effective decision to overcome this issue. United Nations are need to show her presence on this issue because United Nations are established for resolve that type of issues which gives a peaceful world
