Symptoms of the Novel H1N1 flu are mostly in the respiratory system including cough and runny nose, and sneezes. It aggravates underlying chronic respiratory diseases such as Asthma, chronic obstructive pulmonary disease, and emphysema. It can have secondary bacterial infections associated like bronchitis, and sinusitis, and in the more severe cases, pneumonia and respiratory failure.
It will affect mostly mammals and sometimes birds.
Mostly the mucous tissue in the respiratory system, but mucous tissue in the gastrointestinal system is also affected.
H1n1
There are many different viruses that can cause respiratory illness. One that has been in the media is H1N1, also known as the swine flu.
It is possible but less likely since the respiratory system is attacked by the H1N1/09 virus. In very early stages of the infection you may not have a cough. See the links below for related questions about the symptoms of the pandemic flu and for a link to a web site for a self assessment tool.
H1N1 refers to a subtype of the influenza virus, not a bacteria. Influenza viruses can cause respiratory illness in humans and animals. It is important to note that viruses and bacteria are different types of microorganisms that can cause different types of infections.
H1N1, the virus responsible for the swine flu, can have significant effects on the heart, particularly in individuals with preexisting cardiovascular conditions. The infection can lead to inflammation of the heart muscle (myocarditis) and exacerbate underlying heart diseases. Additionally, severe respiratory symptoms can cause increased stress on the heart due to reduced oxygen levels and increased heart rate. Overall, H1N1 can contribute to serious cardiovascular complications, especially in vulnerable populations.
The effects are to make you immune to the virus by stimulating your immune system to respond to the tiny amount of virus in the vaccine and build up a defense for if you are ever exposed to the virus in the "wild". The way the effects are created by vaccines is described in the related question below.
The major cells affected by influenza viruses, including swine flu H1N1/09, are those in the respiratory system mucous tissues.

THE COMMON RESPIRATORY DISEASES ARE -COMMON COLD, COUGH, ASTHMA, CHRONIC OBSTRUCTIVE PULMONARY DISEASE ( DUE TO SMOKING ), TUBERCULOSIS (ESPECIALLY IN INDIA), PNEUMONIA, PLEURAL EFFUSION, LUNG CARCINOMA ETC. The respiratory system is a group of organs that help you breath. Therefore it consists of the airways, ie, nasal passages, the trachea (windpipe), the lungs, pleura (pleura is the double membrane covering of the lung and respiratory muscles. Diseases of any of these parts are termed as respiratory diseases. They can be grouped into -congenital anomalies (present since birth), acquired diseases, and tumours. CONGENITAL ANOMALIES (NOT SO COMMON)- agenesis or hypoplasia of lungs or its lobes, tracheal and bronchial atresia,stenosis, trabeoesophagial fistula etc. ACQUIRED DISEASES- asthma, emphysema, bronchitis, bronchiectasis, pneumonia, sarcoidosis, tuberculosis, pneumoconiosis, hypersensitivity pnemonitis, pulmonary edema, pulmonary hypertension, pulmonary embolism, pulmonary haemorrhage, Good-pasteur syndeome, pleural effusion, pneumothorax etc. TUMOURS- benign and malignant tumours of the lung, pleura and various metastatic tumours.
The H1N1 virus does not typically lay dormant in the human body like some other viruses, such as herpes viruses. Instead, it usually causes an acute respiratory infection that the body clears relatively quickly. After infection, the immune system generally eliminates the virus, and any remaining antibodies provide protection against future infections. However, like other influenza viruses, H1N1 can mutate, leading to new strains that may evade immune protection.
