A virus or illness causing fever and headache: flu.
Norovirus has overtaken rotavirus in causing most gastric illness
The measles virus is transmitted via respiratory secretion and causes very serious illness. It first infects the conjunctiva, respiratory tract urinary tract and the central nervous system.

Respiratory syncytial virus (RSV) was first discovered in 1956 during research on a respiratory illness in chimpanzees. The virus was isolated from these animals and later identified as the cause of respiratory infections in infants and young children. Since then, RSV has been recognized as a significant pathogen, especially in pediatric populations.
RSV stands for respiratory syncytial virus, the most frequent cause of serious respiratory tract infections in infants and children younger than 4 years of age. RSV causes nasal stuffiness and discharge, cough, and sometimes ear infections.
The Mumps virus is characterized by swelling of the parotid glands, salivary glands and other epithelial tissues, causing high morbidity (illness) and in some cases more serious complications such as deafness or damage to the testes.
No, the stomach flu and influenza are not the same thing. Influenza is a respiratory illness caused by the influenza virus, while the stomach flu is a gastrointestinal illness caused by various viruses.
Pneumonia is a respiratory illness.
An example of a virus is the influenza virus, which causes the seasonal flu. It is a contagious respiratory illness that can range from mild to severe, and it spreads easily from person to person through droplets in the air.
To get sick with a virus, you typically need to be exposed to the virus itself, which can occur through direct contact with an infected person, contaminated surfaces, or respiratory droplets. The virus must then enter your body, often through the respiratory tract, mucous membranes, or breaks in the skin. A weakened immune system or underlying health conditions can increase susceptibility to infection. Once inside, the virus can replicate, leading to illness as your body responds to the infection.
Viruses can affect their hosts in various ways, depending on the virus type. For instance, the influenza virus can cause respiratory illness by infecting and damaging the respiratory tract cells, leading to symptoms like fever and cough. HIV targets the immune system, specifically CD4 T cells, eventually weakening the host's ability to fight off infections. Lastly, the herpes simplex virus can cause localized lesions and blisters, establishing latency in nerve cells that can reactivate later, causing recurrent symptoms.
