What is Hong Kong's flu?

Hong Kong influenza is a type of seasonal influenza, which is due to the subtype of the influenza virus called H3N2. The H3N2 tribe is able to infect birds and mammals such as humans. It causes symptoms similar to the symptoms of common colds, so people often ignore it until their conditions deteriorate. However, Hong Kong influenza can cause serious illnesses and even lead to death if it is not properly solved.

As well as any other influenza virus, the H3N2 subtype has two different proteins on its surface. These proteins are called Hemagglutinin, represented by the letter H and neuraminidase, represented by the letter N. It is assumed that they have been formed due to antigenic shift or gene recharge of various existing flu tribes. In particular, it has been shown that the H3N2 subtype has genes from existing bird tribes, pigs and human influenza A.

The H3N2 influenza virus can cause Hong Kong flu when it is transmitted from a person who has a virus per person who is not immune to The virus. Transmission can occur differentMi routes. The most common routes are through direct contact and respiratory droplets. This means that simply being in the same room with an infected person or touching his belongings could lead to the transfer of Hong Kong influenza.

It is also said that the H3N2 virus can be transmitted by gastrointestinal; hematogenic or blood; and sexual routes. The person can be infected by consuming contaminated food, undergoing a transfusion contaminated with blood or sexual contact with an infected person. Fetal transfer can also occur when a pregnant woman gets a virus.

Symptoms include runny nose, nasal overload, cough and sore throat. Headache, fever, joint and muscle pain, chills and fatigue may also occur. Symptoms usually last about 4 to 5 days. The patient may feel so ill that they lose their appetite and weak. If not properly solved, the disease may lead to pneumonia and asthma or chronicObstructive lung disease (COPD). In children, this may result in high fever and seizures. It can also lead to fetal development problems during pregnancy.

Rest helps in recovery and prevents further virus transfer. Aspirin or paracetamol may be accepted to alleviate fever and pain. Sufficient fluid intake is necessary to prevent dehydration. The physician may give antiviral drugs such as oseltamivir or zanamivir if it is considered appropriate.

The world's first pandemic appeared between 1968 and 1969, and it was believed that it caused a million deaths. This disease still holds a pandemic status because it affects more countries annually. The World Health Organization (WHO) considers it a pandemic of the flu 2 because it only causes the death rate per case 0.1 to 0.5 %. This means that for every thousand people affected by the flu, one for infection. Therefore, compared to other influenza pandemics such as a severe acute respiratory syndrome (SARS), HO HONgkong influenza pandemic is considered mild.
