Answer 1

SymptomsThe symptoms of common cold are well known to most people.

The symptoms of the common cold are the body's reaction to the cold virus. It triggers the release of chemicals, making the blood vessels leak, causing the mucous glands to work harder.

The most common symptoms of a cold are:

dry throat
sore throat
cough
mild fever
sneezing
hoarse voice
blocked nose
mild headache

Rarer symptoms of a cold include:

muscle aches
shivering
pink eye
weakness
reduction in appetite
extreme exhaustion

Some people do not suffer any symptoms when infected with the cold virus, perhaps because their immune system reacts differently to the virus. Sometimes, bacteria can infect the ears or sinuses during this viral infection — this is known as a secondary bacterial infection — and can be treated with antibiotics.

Causes

The common cold can be caused by more than 200 different viruses. Around 50 percent of colds are caused by rhinoviruses, other cold-causing viruses include:

human parainfluenza virus
Human metapneumovirus
coronaviruses adenovirus
human respiratory syncytial virus
enteroviruses

When a virus manages to overpower the body's immune system, infection occurs. The first line of defense is mucus, which is produced in the nose and throat by the mucus glands. This mucus traps anything inhaled, such as dust, viruses, and bacteria. Mucus is a slippery fluid that the membranes of the nose, mouth, throat, and vagina produce.
